London Gatwick Airport deploys new radio system from Motorola Solutions

Back in the day, around 2006, the Heathrow and Gatwick radio systems were the envy of many, many businesses, a cutting-edge Motorola analogue trunking system with individual and group setup, that could broadcast messages out across the site or talk to individual radios, something that is taken for granted these days with our digital systems. The Gatwick system has been upgraded and been given the digital touch.

US-based Motorola Solutions, along with its authorised channel partner Servicom, has debuted its new digital mobile radio (DMR) system, Mototrbo Capacity Max, at London Gatwick Airport.

Designed to provide enhanced voice and data communications, the newly installed system connects 1,300 people in the airport’s airside and groundside teams.

Mototrbo Capacity Max will also double the capacity of Gatwick’s current analogue network.

Various applications, such as TRBOnet PLUS and iBeacon, were given along with Mototrbo Capacity Max to improve its data performance.

TRBOnet PLUS is a dispatcher application that allows voice recording, mapping and event logging in the control room, while the iBeacon indoor positioning application sends alerts to individual radios based on location.

Gatwick Airport IT project manager Simon Telling said: “We chose Motorola Solutions’ Mototrbo Capacity Max system not only for how resilient and secure it is, but because of the flexibility it offers us now and into the future.

“We have experienced significant growth over the past decade and we are now approaching the limits of our previous analogue system.

“Migrating to scalable, digital communications will double our capacity and bring new capabilities that will help us improve efficiency and safety for staff, retail partners and passengers across the airport.”

The new Motorola solution will also enable Gatwick’s central controllers to send off the closest employee to an incident, saving time.

The airport recorded more than 4.6 million in passenger traffic in July.

Precisely what does earpiece mean

Almost all adults have used an earpiece at some point in their lives. An earpiece is actually a gadget placed on the ear and is usually used for listening to something. Millions of people normally use an earpiece for different reasons. In this article, we are going to explain in details different uses of an earpiece .

The first very common use of an ear piece is connection to a wireless radio. Wireless radios usually consist of earpiece cable that usually connects the radio to the user. This is very common especially in sports such as cricket where people usually follow the game from the radio. The earpiece is usually plugged either on a single ear or both ears.

Stethoscope is a type of earpiece that is mostly used by medical practitioners. This earpiece is a bit different from the normal ones and it needs to be carefully inserted into the ears so as to provide an excellent acoustic seal as well as make the user comfortable. This type of earpiece usually snaps firmly to the ends of the ear tube and requires special skills in order to safely remove them after use.

An Earpiece is also used as a hearing aid. This type of earpiece is either made from plastic that has been well molded to fit the exact shape of your ear or with a thin plastic dome known as open fitting that is usually fitted inside the ear. This type of earpiece is available in different categories and its suitability usually depends on the user degree of hearing loss. It has a microphone that fits behind the ear as well as an earpiece that perfectly fits on the ear. Custom made earpiece usually differs slightly from the normal earpiece in that it is usually made from a clear plastic known as NHS behind the ear hearing aids.

Did you know that an earpiece is usually used on 2 way radio? The radio earpiece is available in variety of styles. Some of the styles include D-ring, clear tube and over the ear. Earpieces for two way radios are usually used on many different radio brands including Kenwood, Motorola, Icom and Binatone. In addition to that, it is also used by bar staff, door supervisors and security staff.

Most people usually wonder how TV presenters communicate with the producers. Typically Presenters use an earpiece to receive instructions or information from the director. They can also receive messages from a device that plays a recorded script. A Presenter earpiece is available in two categories: wireless ear bug or tube earpiece. These types are usually very small and cannot be seen unless you look keenly for them. They are used by all type of presenters either in studio or out in the field as well as those in live broadcast and entertainment field.

Thousands of people use earpieces to listen to music on their phone IPod and mp3 players, They are also used to communicate on the phone. Typically, an earpiece usually fits both ears and the style that is commonly used is white. They are also used by sound engineers, musicians, audiophiles to listen to their own vocals, music, and stage instrumentation during live performance or when recording studio mixing. In most cases, the earpieces are usually customized to provide comfort and noise reduction from the surrounding to the user.

So the big question is, what is the difference between an earphone and an earpiece? The main differences between these two devices are; an earpiece a speaker is near or inside the ear while the earphone is a traducer that converts electric signals to sound and it is usually held near the ear. An earpiece has both its pros and cons. Some of the benefits of the earpiece include being lightweight and portable. It is also small in size and cannot be seen easily. Common disadvantages associated with earpieces include not being able to filter external noise properly and having problems receiving sound from them especially if there is a lot if background noise.

LeBlanc: Protect your hearing it is irreplaceable

This is an excellent story about how hearing protection is sometimes be essential, and when you’re on the shooting range it has to be vital. But it is important to get the right set of headphones that will protect your hearing sufficiently. Lessons can be learnt from this excellent case study.

There is no doubt that we all take our senses of sight, smell, and hearing for granted as long as we are strong and healthy and everything is working well. When we are young we tend to believe that we are indestructible and readily adopt the idea that “it will never happen to me.” Consequently, we can develop some bad habits and be a little loose when it comes to preventative measures for almost anything.

I know because that was my attitude at thirty years old when my eye doctor made a comment in passing that my eyes were perfect, but the chances are I would be needing reading glasses by the time I was 50. I scoffed, but you could almost have set your watch by it because by the time I was in my late 40’s my arms started to get shorter when it came to reading, tying on fishing lures and other things that required scrutiny up close. At 50 I was wearing reading glasses.

Growing up I never bothered too much about wearing ear protection. When I was plinking it was with a .22 rifle that only put out a little noise if you were the shooter so the thought of hearing protections seemed ludicrous. When hunting I do not know if I have ever heard my firearm discharge and beside that unless I was dove hunting I seldom shot too many shots anyway.

The change of heart came when I started shooting on an indoor range, while in the Air Force. I noticed after shooting a few rounds with my .22 caliber, Ruger Single Six that my ears would ring for a while afterward. One night a grizzled old Master Sargent suggested I wear ear protectors or take a chance of damaging my hearing. I took the recommendation to heart and have been wearing them ever since. The result has been that after many years of shooting .22’s, large caliber handguns, rifles and shotguns my hearing is still intact and working well.

Shooting is not the only activity that can cause hearing problem as any loud noise can damage your hearing. The intense vibration caused by loud noises can injure or destroy the hair cells inside the cochlea, so they no longer function to transmit nerve impulses to the brain. If that happens, you will experience hearing changes.

Hearing protection is needed anytime one is exposed to sounds above 80 decibels (dB). Normal human conversation runs about 30 to 35 dB. At its peak level, the sound of a 12-gauge shotgun is about 140 dB. 9mm runs around 159 dB and a .38 special with a six-inch barrel is about 156 dB, a .22 LR pistol with the same length barrel 140, an M-16 is about 154, a .45 ACP pistol is 155, and a .357 Magnum revolver is 164. All of them are around double the safe sound level. Just to be on the safe side I used to wear muff type hearing protectors and usually ear plugs also when on the range.

For range use today there is an array of muff style hearing protectors. The new style that I now use have not only hearing protection, but also hearing enhancement. The controls on each ear can be tuned to match your individual optimum hearing and increase the volume up to eight times normal. So when the range master gives a command or when you are speaking with a companion on the shooting line you can speak in a normal voice and hear them as well or better than without the power muffs. Yet when you shoot the sound activated compression circuit reduces the sound from the shot to a noise reduction rate of 24dB.

This is very important on a shooting range because I have missed range commands in the past from the range master simply because I could not hear them through my hearing protection.

The new muffs I use are from Walker’s but they offer many other styles in their Game Ear series. These are unlike the muff style protectors as the bulk of the unit fits behind your ear with an earpiece that fits inside your ear, the unit weighs less than one fourth of an ounce and can be used with or without glasses. These too can be fine-tuned to your specific hearing, allow you to turn the volume up to magnify sounds from five to seven times and still reduce the sound of the shots to a rating of 29dB.

The ability to custom tune the devise to your hearing as well as adjust the volume up on these models will enable the hunter to more readily pickup games sounds in the woods. Sounds like a squirrel jumping through the trees or when their belly slaps a tree when they jump from one to another. It will help the hunter pick up the minutest sound of a deer brushing by limbs or the whisper of them walking through leaves or disturbing a rock.

So now there is really no acceptable reason not to wear hearing protector and if you get a good set it may even enhance your chances of bagging some more game.

A giant solar storm nearly triggered a nuclear war in 1967

We all know how important radio communications are and at a time before the internet and even digital communications, governments relied on RF communications that were susceptible to the suns solar storms, if you add that to the cold war nuclear tensions then we could all be living in holes now.

Cold War history is rife with close calls that nearly led to nuclear holocaust.

In September 1983, for example, sunlight reflecting off a patch of clouds fooled a Soviet missile-warning system into detecting the launch of five US intercontinental ballistic missiles that never were. A wary colonel in a bunker ignored the alarm on a 50/50 hunch.

Two months later, US forces staged “Able Archer 83” — a massive nuclear-strike drill on the doorstep of the USSR. Soviet commanders panicked at the show of force and nearly bathed America in thermonuclear energy. Once again, an act of human doubt saved the planet.

Now scientists have one more hair-raising event to add to the books: The “Great Storm” of May 1967.

“The storm made its initial mark with a colossal solar radio burst causing radio interference … and near-simultaneous disruptions of dayside radio communication,” a group of atmospheric scientists and military weather service personnel wrote in a new study, published August 9 in the journalSpace Weather.

Hours later, high frequency communications dropped out near US military installations in and near the Arctic — one of the closest places to station nuclear weapons and launch them at a Cold War-era Soviet Union.

“Such an intense, never-before-observed solar radio burst was interpreted as jamming,” the study authors wrote. “Cold War military commanders viewed full scale jamming of surveillance sensors as a potential act of war.”

A ‘Great Storm’

Earth’s magnetic field protects life on the planet by corralling the sun’s high-energy particles toward the planet’s polar regions.

If the sun happens to launch a cloud of solar particles directly toward Earth during a violent outburst, called a coronal mass ejection, it can trigger powerful geomagnetic storms.

This not only leads to beautiful auroras, but can also scramble wireless communications and disrupt radar systems.

City Gets Rare Look at Northern Lights,” top US military commanders sounded the alarms in secret.

The Air Weather Service (AWS) — a relatively new branch of the Air Force — had warned military leadership about the possibility of a solar storm, but US commanders believed the Soviet forces were jamming NORAD systems designed to detect threatening planes and missiles.

As the Strategic Air Command warmed up the engines of bombers and taxied toward the runway, the decision to go airborne may have been kicked all the way up to the “highest levels of government,” possibly involving President Lyndon B. Johnson.

“Just in time, military space weather forecasters conveyed information about the solar storm’s potential to disrupt radar and radio communications,” according to a press release from the American Geophysical Union. “The planes remained on the ground and the U.S. avoided a potential nuclear weapon exchange with the Soviet Union.”

And this all happened at the peak of nuclear armament — when a record 31,255 nuclear weapons were deployed around the world. (Today there are roughly 7,200 nuclear armaments at hand.)

“Had it not been for the fact that we had invested very early on in solar and geomagnetic storm observations and forecasting, the impact [of the storm] likely would have been much greater,” study leader and UCAR atmospheric scientist Delores Knipp said in the release.

After the near miss, the researchers say the military learned to listen to its space weather forecasters, improve its abilities to see another looming “Great Storm,” and avert the first and perhaps final global nuclear exchange.

Exactly What’s The Earpiece Singers Use Why Do Singers Put On Earpieces About Stage

Every time a singer gets on stage, he or she wants to put on his/her best performance ever. This is why he/she will try to avoid any distraction that might otherwise affect his or her performance in a negative way. They will ensure that their concentration is really high and that they can hear themselves sing during that moment. One of the distractions that is usually in almost every concert is noise. The noise can be coming from the speakers, the echoes and even form the audience itself.

The music and the song that is normally heard when a singer is performing is referred to as house mix while the song that the singer hears from the speakers is referred to as monitor mix. Usually, a singer stands at the back of the main speakers that are normally placed in front of the audience. Most of the time especially on a big stage, the song that reaches the audience is reflected back to the stage (but not immediately). Such background music will prevent the singer from hearing his or her voice.

Stage monitors are small speakers that are directly aimed at the singer for him or her to hear himself or herself sing. Stage monitors were previously used in concerts and they are still being used on some small venues where cover bands do gigs e.g. in some private parties, bars etc. In the current concert venues, stage monitors do not work very well. This is because singers and musicians move a lot on stage when they are performing. Although the stage monitors enable the singer to hear the music on the stage, they are not as clear as personal monitors (referred to as earpieces, very different to Radio Earpieces).

Earpieces give the singer a detailed information regarding his or her performance. They make him/her hear both the song and the orchestra. They enable the singer to constantly hear his/her song regardless of his or her physical movement on the stage. This is unlike the stage monitors that usually provide the band’s and the singer’s voice based on their distance from the speaker. With stage monitors, the sounds usually vary especially if the singer is moving all over the stage.

When a singer has the earpieces on, he gets to choose what he wants to hear. For instance if he wants to hear himself sing or even hear the lyrics, he can. The earpieces help in drowning out the background sounds like the noises made by the crowd or even those from the band. In fact on average, the earpieces can help the singer reduce the background noise by up to 30 decibels. This can extremely help the singer during the performance.

Usually, the earpieces are tailor- made to perfectly fit the singer. They also come in different styles and colors and therefore the singer can pick the one that suits his/her outfit on the stage.

The most important benefit of having the earpieces on is that, they help the singer in eliminating or reducing the echoes. In an auditorium specifically built for concerts, sounds usually radiate through the entire building when the singer is performing. The audience really enjoy the music that echoes back to the stage however, the singer can easily get confused with such echoes. Note that, by the time the echo reaches the stage, it will be one or two seconds off from what the singer is singing at that moment.

Earpieces also help in blocking the sounds that are coming from the band. The instruments are extremely loud especially those that use electric amplifiers. This noise can make it really hard for the singer to hear himself or herself sing.

The earpieces give the singer the sound feedback and therefore he/she is able to hear everything that is in the song. This makes it easier for him/her to keep on with his or her performance.

Sometimes, you may notice that some garage bands who work in small areas are not using earpieces. The members of such bands usually monitor one another while performing to ensure that they keep up and stay in tune during the performance. However in large crowds of say a 100000 people (i.e. in huge stadiums), one will definitely need earpieces otherwise he/she may not hear anything and may even end up with off key sounds.

Army to Launch Another Competition for New Soldier Radio

In the modern world the army has to have perfect communications, from coordinating attacks to communicating with other platoons, on the battlefield it really could mean the difference between life and death. This article plans to find the next Military radio.

U.S. Army tactical radio officials plan to launch a competition for a new handheld radio next year that would give soldiers twice the capability of the current Rifleman Radio.

The Army currently uses the single-channel AN/PRC 154A Rifleman Radio as its soldier handheld data radio. It runs the Soldier Radio Waveform, which small-unit leaders use to download and transmit maps, images and texts to fellow infantry soldiers in a tactical environment.

If they want to talk to each other, they often rely on another single-channel handheld — the AN/PRC 148 MultiBand Inter/Intra Team Radio, or MBITR, which runs the Single Channel Ground and Airborne Radio, or SINCGARS, for voice communications.

The Army plans to release a request-for-proposal in 2017 for a two-channel radio that will allow soldiers to run the Soldier Radio Waveform, or SRW, for data and SINCGARS for voice on one radio, according to Col. James P. Ross, who runs Project Manager Tactical Radios.

The change will mean that soldiers will no longer need the 148 MBITR and be able to rely on the new, two-channel radio for both data and voice communications, Ross said.

“We know industry can meet our requirements. … We know it’s achievable,” he said.

The move represents a change in strategy for the Army since the service awarded contracts in 2015 to Harris Corporation and Thales for a next-generation version of the Rifleman Radio.

“We went out with a competition for the next generation of the [Rifleman Radio]. Two companies, Harris and Thales, competed,” Ross said. “We went through testing, and we were on the verge of being able to buy more of them when the Army said, ‘Our strategy now is two-channel.’ ”

The Army had planned an initial buy of about 4,000 Thales AN/PRC-154B(V)1 radios and Harris AN/PRC-159(V)1 radios, according to Army program documents for fiscal 2015.

“We will not be taking action on those,” Ross said.

The current Rifleman Radio was developed as part of the Handheld, Manpack, Small Form Fit, or HMS program. HMS radios are designed around the Army’s tactical network strategy to create secure tactical networks without the logistical nightmare of a tower-based antenna infrastructure.

It’s also a key part of the Army’s Nett Warrior system. It hooks into an Android-based smartphone and gives soldiers in infantry brigade combat teams the ability to send and receive emails, view maps and watch icons on a digital map that represent the locations of their fellow soldiers. The concept came out of the Army’s long-gestating Land Warrior program.

The Army purchased about 21,000 Rifleman Radios under low-rate initial production between 2012 and 2015.

Army officials maintain that are enough single-channel, handheld radios already produced under the low rate initial production that are sitting waiting to be fielded. The service plans to field another two brigade combat teams per year with the single-channel Rifleman Radios through 2019.

The Army will conduct testing of two-channel radios in 2017 and early 2018 and then down-select to one or two vendors sometime in 2018, Ross said. Operational testing is scheduled for 2019 and fielding will begin in 2020 if all goes as planned, he added.

For now, the Army intends to field four BCTs a year with two-channel handheld radios, Ross said.

Small-unit leaders would then be able to retire the MBITR radio from their kit — a weight savings of about three pounds, according to Army officials at Program Executive Office Soldier.

“One thing the PEO Soldier is very passionate about is weight — driving that weight down that the soldier carries,” said Lt. Col. Derek Bird, product manager for Ground Soldier Systems, which helps oversee the Nett Warrior program.

“If we can cut three pounds off a soldier by taking two radios and shrinking it to one … that is a big deal.”

Those New Tracks You’re Listening to Are About to Sound Much Better

SO you’re walking down the street and suddenly the music kicks in, you drop to the ground and pull your earphones out of your ears! “what just happened” you think, then you realise the un-pause on the mp3 has just kicked in and you forgot to turn it down. Well people this will be a problem of the past with these earphones, Now all I need them to do is make coffee. VERY IMPORTAN You can find the original article here

What’s been your favorite set this weekend? Or the best new track you’ve shared with all of your friends? Well take that track and imagine listening to it in exactly the way your ears want you to.

Meet the Even earphones, who tune themselves to each person’s particular hearing. At just under $100, they customize the sounds they play to suit your own audio needs. They use their own EarPrint technology that measures how you hear different frequencies, then sets the earphones to play back sound specifically for each ear. As a result, the headphones give you a profile tuned to your own ear (each ear with its own profile).

One of the biggest things that originally drew me to the earphones was the fact that they are not a pre-order campaign – they have physical earbuds available now. The company, who launched in in June, has sold out batches twice thus far and are continuing to take orders on their website. Luckily, I was able to get my hands on a pair to try out as well.

I’m pretty picky about the gadgets I use for audio, as I’m constantly listening to music – digging for new sets on Soundcloud, reviewing new tracks, jamming out in my own world. Being able to plug in and listen to my own music is what allows me to focus and, as a result, I’m very specific about the type of earphones or headphones I use. That being said, I was overly ecstatic when I was handed a pair of Even earphones to try out.

First, their appearance: the cords are a high-quality string that have a smooth look and feel. The buds look sleek, with a simple black-and-white color scheme – one black, one white, with the EarPrint device hanging at the middle of the cord, meant to dangle at your chest. They don’t tangle easily, which makes them easier to carry without having to worry about dealing with knots. They’re the type of earphones I wouldn’t mind wearing out in public.

Next: the sound test. This is where we meet “Sarah,” the soothing female voice that guides you through a number of sounds to test where your hearing level is at. This test was very straightforward – Sarah literally starts by saying “Hi, this is really easy” – and felt very conversational as she talked you through each noise. Five pieces of music are played for each ear, and you’re required to hit the button once you hear the sound. Though the process takes a little bit longer than I’d like, it’s seamless.

Overall quality of the listening experience was great. I switched between my Bose over-ear headphones and the Even earphones to test the difference in sound quality and worked to try a few subgenres of electronic music to see how each would sound between both pairs. I started off by listening to Louis The Child’s set from Lollapalooza this year and instantly found that the vocals were much more emphasized than in my Bose headphones. Next, I moved on to Mikey Lion’s live set from Desert Hearts 2016 and loved the emphasis on the bass I was hearing – the Even earphones made it much more of an all-around experience. I then switched over to Troyboi’s tracks Do You? and O.G. to continue to test this bass theory and, again, Even delivered.

As my hearing is likely damaged based on the amount of festivals and shows I’ve attended over my lifetime, it was much appreciated that the earphones were able to pick up on the frequencies I have more trouble hearing to create the full experience tracks deserve. Interestingly enough, every time I switched back to my Bose headphones to compare, I had to turn the volume down because it came at full blast and was overwhelming – and, when I did, the clarity between vocals and bass was lost. All in all, these babies pack a punch with their sound quality when it comes to electronic music.

It’s refreshing that these earphones don’t require using an app, since that seems so commonplace nowadays. All of the information that goes into your profile is saved in the little box hanging onto the string, so you can plug them into any device – phone, laptop, iPod, whatever you want – and still have your own profile saved. I found this extremely helpful, as it meant that I don’t have to re-adjust my volume based on what device I’m using. Beyond that, it’s a refreshing change from listening to sets with friends and having to change the volume based on everyone’s sensitivities. It makes listening much simpler and, quite frankly, electronic music better. How could you say no to a custom-made, surround-sound system in your own ears?

To get you started, here a few sets, old and new, you may enjoy listening to in the earphones (ok, to be fair, these are sets that I would want to hear in them):

 

Trends in … hearing protection

Many business and factories are very well aware of their legal obligations when it comes to occupational deafness, and here in the UK we have the Control of Noise at Work Regulations 2006. Many of the headsets that are listed on Headsetonline.co.uk are designed exactly for these types of industries, with their experience they are a leader in radio headsets and hearing protection equipment. But as the article below explains the protection has to personalised to everyone, so as to make sure that the individual is catered for and protected adequately. The original source of this article can be found here.

Hearing loss is preventable. Why, then, is it still so common? NIOSH notes that occupational hearing loss is one of the most common work-related illnesses in the United States. And according to OSHA, approximately 30 million people in the United States are exposed to hazardous noise on the job.

“Noise-induced hearing loss is generally a gradual and painless process, so many workers don’t consider it a hazard … until it’s too late,” said Katie Mielcarek, marketing manager for Cleveland-based Gateway Safety Inc. Mielcarek went on to say that workers don’t wear hearing protection for many reasons, including discomfort, poor fit and problems with compliance monitoring and trouble inserting earplugs.

Here, industry insiders discuss what’s new and offer advice on hearing protection.

What’s new

“Electronic muffs contain the latest technology designed to protect against environments with impulse noises,” said Eric Moreno, market manager for Cranberry Township, PA-based MSA. “The technology amplifies weak sounds while compressing dangerous noises to a predetermined safe level of 82 dB or lower.” Moreno said this allows face-to-face communication and lets workers hear important sounds, such as warning signals.

Gary Klee, product manager for above-the-neck products at Latham, NY-based Protective Industrial Products Inc., pointed to a “level-dependent system” available with electronic earmuffs. This system has microphones in both ear cups to help limit sounds reproduced through the internal speakers to a safe level, which “allows communication with others while remaining protected against impulsive or hazardous noise,” Klee said.

Advice

Ricardo Allamelou, COO for Miami Lakes, FL-based Cotral Lab Inc., said providing every worker with the exact same type of hearing protection doesn’t make sense. “The protection has to be personalized since overprotection is as dangerous as no protection at all,” he said.

According to Moreno, “Overprotecting can actually increase the danger to a person’s life because this can hinder their ability to hear relevant noises such as warning signals, moving vehicles, other workers, etc.” To reduce the chance of overprotecting, Moreno recommends thoroughly understanding the level of noise in every area of the workplace to determine what level of protection each area needs.

Additionally, be sure your hearing protection is independently, third-party tested to verify noise reduction ratings, Mielcarek said. “This helps communicate quality in an industry where many manufacturers simply mark their products with a standard or a rating, without the testing to back it up.”

The Sepura Group to Provide Communications for the Olympic Games

It’s a brave move by the olympic organisers, the London Olympic communications was run by Riedel and they did an excellent job, they have experience in this field, but the Brazilians are obviously set on using Teltronic and we all hope that they do just as good as a job.

Teltronic, part of the Sepura Group, has been chosen by the public security secretary of Río de Janeiro State in Brazil to supply communications for the Summer Olympics and Paralympics, informally known as Rio 2016.

The €10m contract will cover four venues (Barra da Tijuca, Copacabana, Deodoro and Maracanã), two airports (Rio de Janeiro/Galeão – Antônio Carlos Jobim International and Santos Dumont) and several key transport routes in the Olympic area.

The agreement with Teltronic will see an extension to the traffic capabilities of the existing Teltronic network currently used by the Rio police, as well as the installation of further Nebula base stations to provide additional coverage for the state police and emergency services, and the Olympics organisation workforce.

The existing network was originally provided by Teltronic for the Pan American Games in 2007 and, after some upgrades, is now supporting over 100 dispatch operators and more than 18,000 radios. This new upgrade for the Olympics will feature two extra TETRA carriers for each site, to update the capacity of the existing network; base stations with up to 12 TETRA transceivers to support high traffic loads throughout the event; a CeCoCo Control Centre, to accommodate a further 50 dispatch operators; an additional 6,000 terminals featuring Teltronic’s Synchronous Data Manager application to pare down the GPS refresh time in AVL applications; and 24/7 maintenance and operational support during the Games.

“This win builds on our long-term relationship with the Brazilian authorities and public safety agencies,” said Paulo Ferrao, the Sepura Group’s sales director for Brazil.

“We have a strong background in events of this scale, having supported communications for the FIFA World Cup 2014 and the Pan-American Games, both huge events in the sporting calendar of Brazil and, indeed, the world. We are delighted that Rio de Janeiro’s public safety agencies have, once again, placed their trust in us.”

Superintendent of critical communications at the Security Secretariat of the State, Colonel Alexandre Corval, commented: “We are extremely happy to have chosen Teltronic.

“The company has been a trustworthy partner to our public safety agencies for over ten years. Once again, they have exceeded our expectations in terms of technical development, quality of the deployment and, above all, their dedication to customer service: throughout the project, they have paid close attention to our technical and operational requirements.

“We are confident that this extension to the existing Teltronic TETRA system will optimise our mission-critical communications, enhancing the security of both visitors and employees throughout Rio 2016.”

US Presidential Candidate Mocks Disabled Reporter

All-American nutter Donald Trump is back in the news again, this time for making fun of the disabled.

The would-be American President jerked his arms around and acted confused in order to mock disabled journalist Serge Kovaleski, who suffers from arthrogryposis, a congenital joint condition that severely affects his limbs, particularly in his right arm and hand.

One might argue that Trump was just doing an impersonation of an idiot (something he does very well) as a way of slighting Kovaleski’s reporting. From there, one could surmise that the whole thing has been blown out of proportion by an overly sensitive media, until one realizes that Mr. Kovaleski reported on Trump between 1987 and 1993 and that the pair have actually met face to face on numerous occasions.

So, why this latest outburst? Trump was once again using a mis-read article to back up a completely fabricated claim. In this reporter’s opinion, he really should try reading some of these articles ALL THE WAY THROUGH, RIGHT TO THE END, especially if he plans to continue quoting them in public.

Anyway, here’s the story. In 2001, during the aftermath of the September 11th attacks on the World Trade Centre, then-Washington Post journalist Serge Kovaleski reported that Jersey City Police had “detained and questioned a number of people who were allegedly seen celebrating the attacks and holding tailgate-style parties on rooftops while they watched the devastation on the other side of the river”.

Apparently Trump was the only spectator to the “thousands” of Arab-Americans that he claims to have seen celebrating as the twin towers fell. There are no reports anywhere in the media that this rally (or anything even remotely matching Trump’s vivid descriptions) actually happened. Even the mayor of Jersey City has come forward to refute Trump’s bizarre claims, calling them “plain wrong”. Amazingly, Trump himself appears to have waited for 14 years before going public with this shocking sight that only he bore witness to.

BZZZD! Whoops, there goes my bullsh!t detector again!

Mr. Kovaleski’s current employers, The New York Times, have called his actions “outrageous” and, in retaliation, Mr. Trump has taken the fight to Twitter, calling the publication “dumb” and criticising their “poor” management, amongst other things.

Yeah, that’ll show em! How dare they stand behind a disabled employee who has been publicly victimised!

This new outburst was just the latest in a long line of such statements from what appears to be a very public mid-life crisis which has been offensive, painful, embarrassing and laugh-out-loud funny to watch, usually at the same time.

And you thought George Bush was a douchebag!

Can Headphones Cause Me To Go Deaf?

According to MRC Institute of Hearing and Research, one in every 6 grownups has sufficient hearing loss to cause problem in social situations. According to the World Health Organization, loud music is the single biggest cause of preventable hearing problems. So you have to assume that the pounding bass delivered right in the sensitive part of your inner year is not a wise idea. Can it. Keep on reading to answer the question “can headphones make you deaf?”

Dr. Foy a Doctor of Osteopathic Medicine says that listening to music through headphones at a very high volume for a long period of time may lead to lifelong loss of hearing for kids and teens. He adds that even mild hearing loss as a result to loud noise may lead to developmental delays language and speech.

The DOs or Doctors of Osteopathic Medicine, look beyond just symptoms to understand perfectly well how environmental and lifestyle factors can affect your well being. They will listen and partner with you to assist you to prevent injury and encourage the natural tendency of your body toward self –learning.

So, how loud is too loud?

Today, majority of MP3 players are able to produce up to 120 decibels of sound, equal to the sound level at a rock concert. At this level, you can lose hearing after only about one and quarter hours.

Dr. Foy stresses to parents and patients that if you are unable to hear anything going on around you while listening to music on headphones , the decibel level is very high. He advises that headphones users should not go beyond 60% of maximum volume while listening to music through headphones.

Lay it loud

It is obviously not damaging to listen to music through your headphones at half the volume of your player. It all depends on how loud the volume is and how long your headphones are on your ears. The world health organization has laid down guidelines as to what decibels are acceptable. Majority of companies manufacturing music players adhere to these guidelines. However constant exposure is still a major problem. It is very dangerous to crank up the volume for a long period of time and may lead to partial deafness. The higher your volume gets the lesser amount of time your ear can take it.

Uncomfortably numb

Unlike individuals who lose hearing during a bomb blast or hearing that sonic boom of an airplane, loss of hearing caused by headphones creeps on your ear and if not contained, its effects can be dangerous. There are people who do not show any signs of deafness during their childhood and hardly hear anything when they are in their sixties. Studies have shown that this is very common for individuals who listen to loud music through the headphones or attend a lot of clubs or live concerts. Deafness brought about as a result of listening to loud music through headphones doesn’t happen overnight. Your ear will warn you before things get really bad with tinnitus.

Conclusion

The question “can headphones make you deaf?” depends on several factors. Duration and level of volume plays a key role. If you limit the duration of time you listen to music through the headphones and also keep the volume low and soft, you will not experience problems with hearing. On the contrary, listening to loud music for a very long time through the ear phones will no doubt impair your hearing ability or worse still make you deaf. The best thing is to adhere to the guidelines laid down by the World Health Organization.

The Effect of Earplugs in Preventing Hearing Loss From Recreational Noise Exposure (A Systematic Review)

This is an interesting review of a study of how effective ear plugs are in the workplace. We take for granted that people working in loud factories wear protective hearing, but many of the clubs, pubs, concerts and festivals that have as equal levels of sound. As they say below, it isn’t mandatory to wear ear plugs in such environments, which defies common sense and possibly causes more damage than we understand. Here you can find the original source of the review.

A review of the literature turned up only two high quality studies that looked at whether wearing earplugs to music venues will prevent hearing loss and tinnitus directly afterward.

Dr. Wilko Grolman and colleagues at University Medical Center Utrecht in The Netherlands searched for published studies containing the keywords “music” and “earplugs” and screened 228 resulting papers. All but four were not eligible for inclusion in the review and only two were highly relevant and did not have a high risk of bias, in the reviewers’ estimation.

Two studies simply examined people who chose on their own to wear or not wear earplugs, while two randomized controlled trials tested what happened when participants were assigned to wear earplugs or not.

Two studies reported on hearing loss and tinnitus while one only reported hearing loss.

The two best studies were different enough that the researchers couldn’t combine their data and analyze the results, the reviewers wrote. Both included 29 concert attendees and performed audiometry before and after the concerts. In one study, participants were allowed to choose whether or not they wore earplugs, and only three chose to wear them.

“Frankly, with such a small comparator group between three subjects and the others, it would be hard to assess validity of plugs or not,” said Dr. Jennifer Derebery, president of the Los Angeles Society of Otolaryngology and lead author of the first study.

“We had trained them all in proper insertion, and encouraged but not required wearing them,” Derebery told Reuters Health by email.

In the other study, 15 participants were assigned to the earplug group.

In general, wearing earplugs did reduce hearing loss directly after the concerts, but did not eliminate it completely, as reported online March 3 in JAMA Otolaryngology-Head and Neck Surgery.

“Ear plugs are effective in preventing hearing loss when they are used both correctly and consistently,” said Colleen G. Le Prell, the Emilie and Phil Schepps Professor of Hearing Science at the University of Texas at Dallas, who was not involved in the review.

“This systematic review highlights the very limited data on prevention of recreational music-induced hearing loss using earplugs,” Le Prell told Reuters Health by email.

“At younger ages, loud toys, firecrackers, loud video games, personal stereos or personal music players, lawnmowers or leaf blowers, sporting events or air shows, or other non-music events might be more likely noisy activities than music venue attendance,” Le Prell said. “A significant number of youth are also involved in target shooting activities, which children can get involved with through Boy Scouts or other organizations.”

For teens and young adults, repeat exposures to amplified music at clubs, concerts, festivals, or other related events may damage the inner ear and result in hearing loss, she said.

“Most concerts are both loud enough, and long enough, that they are likely to exceed the total daily exposure allowed by workplace safety regulations,” she said. “Sound exposure also commonly occurs via loud music delivered via personal listening devices, at sporting or other recreational events, and at jobs that involve lawn-mowing, use of power tools, or construction services.”

For workplace noise exposure, “we are not doing a very good job achieving correct and consistent use of hearing protection devices (HPD), including both ear plugs and ear muffs,” she said.

“In the United States, it is relatively uncommon for music venues to provide ear plugs at no charge,” Le Prell said. Even if they were provided, people may need to be educated in why using them is important and in how to use them correctly, she said.

“As a neurotologist, it really is upsetting to see these kids coming in younger and younger with a completely preventable hearing loss,” Derebery said.

ETRI presents a blueprint of the 5G Future

We will see a huge change in the way we access the the internet in the future when 5G is here, at speeds that only big businesses and high level internet companies see at the moment, we will have this to hand on our smart phones and tablets. When 5G is hundreds of times faster than any of the UK’s broadbands, households will be looking to the mobile phone companies to supply their home broadband.

A 5G future is no longer a distant one, but an upcoming reality. High quality videos of more than 10Mbps can be served simultaneously to 100 users even in a train running at up to 500km/h. People can experience data rates that are 100 times faster than currently available technologies.

The Electronics and Telecommunications Research Institute (ETRI) of Korea will hold a “5G technology demonstration” on the 18th December, 2015. It will demonstrate future SNS (social network service) and several 5G core technologies such as “millimeter wave”, “Mobile Hot-spot Network”, “in-band full duplex” and so on.

5G is the next generation wireless technology that would provide even faster data rates, even lower delays, and even more devices connected than 4G. Accordingly, distinct and differentiated applications are expected in 5G.

ETRI’s “future SNS” is a kind of trial service model to apply 5G technologies that provides dynamic user-centric connection to neighboring people, things and spaces. It is characterized by instant content-sharing between users, communication with neighboring things, and Giga-bps(Gbps)-grade video applications in vehicles.

5G core technologies demonstrated by ETRI include the following:

— MHN (Mobile Hot-spot Network) is a mobile backhaul technology that provides high-speed Internet access of Gbps in vehicles at speeds of up to 500 km/h (e.g. KTX in Korea). Almost 100 passengers can watch videos of high quality simultaneously.

— ZING is a near-field communication technology that enables mass data to be transmitted with 3.5 Gbps data rate between neighboring devices within the radius of 10cm.

— Single-RF-Chain compact MIMO technology enables a single antenna to simulate the effect of multiple antenna. It can reduce antenna volume and cancel inter-antenna interference in a multi-antenna system.

— Millimeter wave (mmWave) beam switching technology provides fast switching of radio beams to mobile users, and therefore allows seamless Gbps-grade service in mobile environments.

— Mobile Edge Platform (MEP) is a mobile edge cloud server on vehicles that enables passengers to enjoy customized Gbps-grade content and connects them with neighbors, things and spaces. It provides user-centric services.

— In-band Full Duplex technology can transmit and receive signals simultaneously over the same frequency band. It can increase spectral efficiency by up to two times.

— Small cell SW technology is designed for AP(Access Point)-sized small cell base stations that can reduce communication dead zones and improve data rates per user in a hot-spot area.

“With this demonstration event, we are officially introducing our R&D results on 5G. We will continue to lead the development of 5G technologies. Also, we are trying to develop commercialization technologies needed by businesses, and to construct a 5G ecosystem.” said Dr. Hyun Kyu Chung, vice president of ETRI Communication & Internet Lab.

In January, 2016, ETRI will demonstrate Giga internet service and future SNS in a Seoul subway train installed with MHN and ZING kiosks. ETRI will also introduce hand-over technology on a millimeter wave mobile communication system and 5G radio access technology that satisfies 1 millisecond radio latency.

Some styles of Bluetooth earpieces

Bluetooth technology has been designed for many different purposes and situations. Consequently, when people want to buy a bluetooth ear piece for a specific situation, there are some things that they will need to consider. Specifically, based on their specific situation and circumstances, they will need to review the best style of bluetooth earpiece that is available on the market today. Since there are different styles that have been made for for one or more reasons, it’s important for each individual to do their research to see which style can accommodate their needs. It is also important to note that the kind the person purchases must be comfortable so that they can wear them for an extended period of time and they fit the devices that they will be used for. Listed below are three of the bluetooth styles that’s currently offered by manufactures all over the United States and abroad.

Bluetooth ear pieces for Mobile Phones

Most people take their mobile phones wherever they go. To work, school, church, parties and all kinds of other events that they may attend. Because these phones have become commonplace in many environments, people have a need to handle them and talk to others when their hands are free. This is also a great reason for individuals who work in certain settings to make sure that they are buying the right style that will best fit their needs.

One specific style that some people may choose is the ear cradle style of headphone. In fact, this kind of bluetooth earpiece is idea for people who want to spend their time working out and performing all kinds of other extracurricular activities. People are also encouraged to buy this kind of style because they may be driving when they receive a telephone call from a family member. Or, they may be working at the job typing a memo or walking around taking care of wide hosts of other kinds of activities that are not conducive to holding a mobile phone by hand to the ear. Whatever the situation, this style of bluetooth earpiece technology is great for many different situations and purposes.

Bluetooth ear pieces and Headsets for Music Lovers

In addition to the cradle style for mobile phones, people should also review other styles as well. One specific style that is also functional in many different settings is the DJ over the head headphones. This style has been designed for the serious music lovers, especially those who can appreciate making distinctions in sounds and beats that come from specific musical instruments like the bass, violin, trumpet and other popular instruments. For those who like and prefer this kind, they will also find that this is one of the best styles for keeping out outside noises that normally interfere with a person’s overall entertainment experience. Also, because they are wireless, they are great for people who like to stay mobile during the day instead of remaining in a sedentary position.

Bluetooth Ear Pieces for IPODs

In some situations, people may want to use bluetooth technology with their IPODs. Therefore, they should consider buying an additional popular style bluetooth earpiece technology. This style is known to be very popular, specifically because it is similar to an actual earbud. An ear bud is also another excellent choice for people who want to remain both active and hassle free. Though this is a great choice for people who like to remain mobile in a wide variety of different situations, one of its main draw backs is that they tend to fall out of the individuals ear. Which means, they can also be lost since it lacks additional support to keep them stabilized inside the ear.

Learning The Essentials of the Two Way Radio Antenna

An antenna is essentially the most crucial element of a two way radio and other transmitting application such as cell phones, television, radar, or satellite communication. It is responsible for performing the most important task – converting electric power to transmittable radio waves and the other way round.

How an Antenna Works

To transmit a signal, the transmitter provides an electric charge that oscillates at a specific radio frequency to the terminals of the antenna. Consequently, the antenna sends out corresponding electromagnetic waves. During reception, the antenna takes some of the power of the transmitted electromagnetic waves to generate an extremely small voltage for the terminals, which is then redirected to a receiver that amplifies the signals. This is basically how an antenna works.

Extensive Applications

The applications supported by an antenna go beyond communication. The same concept powers today’s high tech wireless applications that run computer networks; Bluetooth enabled systems, garage door openers, and baby monitors. It’s important to know that a perfectly functioning antenna is not only critical to the functioning of your two way radio; it also helps maintain the life or longevity of your equipment.

The Bigger, The Better

The first and most important rule of thumb about an antenna to keep in mind is that the taller it is, the higher your db gain. A high volume of db gain is critical to achieving a stronger reach and better performance of your two way radio equipment . This basically translates to, “the bigger, the better.” However, in order to achieve results in practical situations, the antenna can have only so much height. In essence you have to sacrifice convenience for performance or vice versa. You can’t walk around or even install a gigantic antenna for all your needs, say for example your car radio.

Positioning of Antenna

The second rule of thumb pertains to the positioning of your antenna. The most optimal position for then antenna would be the centre of your metal car roof. In situations where this is not possible, you would need a “no ground plane” antenna. A no ground plane is basically just a metal surface that goes around the base of your antenna so that you have something for the radiating signal to react with. The next aspect you need to consider for your antenna is the frequencies at which you would be transmitting on. A VHF radio transmits and receives in a range from 136 to 174 MHz.

Chubby and Long Antennas

There are different kinds of two radio antennas available depending on how you want to use it. The large stock antenna is powerful and can be replaced or upgraded as you require. The shorter or stubby antenna provides a great deal of convenience. You can add a longer whip antenna to enhance your range. When it comes to two way radios, you stand to gain a great deal of advantages by having a business radio that comes with a removable antenna. The one problem is that removable antennas may not necessarily be compatible with all kinds of radios.

Guide To Which Motorola Connector You Need

Since the 1920’s Motorola has been leading the advancement of radio technology in more ways than one. From the battery eliminator created in 1928 to the world’s first handheld public safety LTE device created in 2012, Motorola truly has been an innovator in the radio world.

There was one of Motorola’s products that stood out and started paving the way for the Motorola brand name. That was their two-way radio systems. In 1978 Motorola introduced the RDX1000. This device was a portable data terminal. With a built-in keyboard and advanced transmitters, The RDX1000 made it possible for a person to share information, like inventory control, wirelessly with a central computer system. It is because of advancements and products like the RDX1000 that Motorola was awarded the National Medal of Technology twice.

Yet, even with being the one of the leading technological companies they still had their issues. For example, the connectors used for their devices, usually, were confusing and weren’t universal like most of our tech is today. Yes, with being in the lead of the industry with innovative products they needed new forms of connectors and pieces that couldn’t exactly be matched by other companies. To be more specific, the connectors to the Motorola earpieces came with their own specific confusions.

Over the course of the years, Motorola devices have had over 50 different types of earpiece connectors. Motorola earpieces are specific to their devices so the pieces chosen had to be precisely specific to the device it was being matched with. You can imagine, with over 50 different types of connectors, finding the correct corresponding puzzle piece that would fit was imperative. The confusion wasn’t just limited to a small portion of the Motorola accessories. Motorola earpieces were different by model of the same device as well. With the earpieces you can’t exactly go by looks either. Most of the earpieces look very similar with very subtle difference.

Even though some had connectors with very similar differences. Differences ranging from appearance and size of the connector to the type of material used in the pin of the connector itself. This confusion also spans over several different years of manufacturing as well. With connectors from earlier years being a small series of pins in lateral form that would only connect to the proper outlet with the proper series of pins. Or like the single pin connector that would only be in a specific size per model, you wouldn’t exactly be able to take a Kenwood connector and confuse it with a Motorola 2-pin connector because on these connectors the pins are of a different size to the Kenwood. Some specific connectors can be understood considering the advancing of the technology as well as the device it connects to has some significance.

The importance of the device does have some control over the type of connector used as well. Because you don’t want to issue and offer a radio and have to worry about it getting lost or stolen and being used for an inappropriate purpose. But, you would expect a device in the same model family to be able to connect or at least the connectors to be somewhat interchangeable. This isn’t the case with Motorola radios. For example, The DP2400 two way radio takes a Clip on block style of connector. While the DP3400 responder radio has to have a Screw in Block  connector in order for the product to be used properly. Even though the station and responder radio are two different products, they share similarities and commonalities. Also you would expect them to share the same connector.

Unfortunately this is the case with many of the Motorola earpieces .

Communication at Events, use Two Way Radios

You have actually most likely seen walkie talkies made use of by cops and security personnel strolling near hotels. The digital age allowed the growth of new devices especially the increase of cellphones. Nowadays, we can send out SMS messages and call people within seconds. However, have you ever thought why two way radios are still around?

The advantages of 2 way radios are a quicker service and less expensive calls. Cellphone businesses charge by the minute for a telephone call or per SMS. There is also no busy tone sent out because the network does not get too congested. This guarantees that a call is carried out right the preliminary time.

Some other individuals who use two way radios are event organizers. As you see in films, they make use of walkie talkies for encouraging 1 another of the activities and whereabouts making sure that every thing flows efficiently. There are a number of people who have them for their kids or for use close to their houses, even. The world of radios has developed quite a bit because its humble starts. They can be produced in very little sizes and can have remarkably strong signals. Such gadgets have been made use of in various emergency situation circumstances and have led to saving many lives.

On the other hand, when radios are bought that are badly made and are not adequate sufficient to perform the method they have to, it can cause extreme concerns. It may assist to know which brands are suggested when it concerns walkie-talkies.

There are four manufacturers that are incredibly recommended for your two way radio requirements . The HYT radio brand is a fantastic option to make. Ritron-not to be confused with Nikon-is another excellent brand that has been depended upon for relatively some time relating to these types of electronics. Selecting a solid brand for your walkie-talkie buy will guarantee you that you have actually produced the right option for your radio requires.

The majority of businesses have retained airing their advertising and marketing their services and products over the radio waves aside from printed media or multi-media. For the two way radio case, it has been widely made use of as coordination device particularly for stock, delivery, and emergency functions. The very best example would be using moving services in land operations like trucking services that makes use of walkie-talkies in communication with their base and update their location from time to time. This assists the trucking workforce to understand what is their job extra directions as well as keep client care by providing details of the status of their cargo.

Schools and other public establishments are also required to have back up communication gadgets like 2 way radios for emergency situations. This is handy especially for events like storms, floods, or any disconcerting coincidence that needs interaction for help or help. In most cases where power outage or disaster cuts off all other phone lines or disable signal protection the two way radio can quickly end up being a trustworthy alternative for communication gadget.

A two way radio for events is one that can both get and transfer on a range of FCC-approved frequencies. A number of elements enter play when it comes time to select the frequency you will be utilizing. Such elements can impact the quality of the signal. Among the most often touted is that these radios will work in surroundings where mobile phone is inoperable.

The ease of operation makes them favourites for individuals in a variety of occupations. Several people make use of a 2 method radio in the office, including construction workers, landscapers, security specialists, and firemens. They are a great and practical way to communicate. All it takes is a simple push of a button and you can speak with your associates.

In the case of a custodial conflict, requiring every child be had a look at and every adult be verified can be done easily with a 2 method radio. At end of day, students are launched to the lunch space, instructors inspect ids in the vehicle line, radio the front workplace to confirm the identity, and then radio the lunch room to dismiss the kid. The process takes 15 seconds and would keep kids much safer.

Complete strangers on campus can be recognized earlier and handled properly. Most schools utilize making use of electronic cameras today. Seeing an unfamiliar person on the video camera and getting a gatekeeper to the unfamiliar person immediately via a two method radio either quickly eliminates the risk or proves the requirement for a more intentional response.

Two way radios should belong of every school emergency situation strategy and provide many benefits in addition to being a security device.

With a two way radio for events, you can talk to numerous people at the same time, making it easier to give and get details. Some of these radios even have a function that allows you to talk to a single person if the info exchanged is personal. The customer support professionals at this website are educated and friendly, and can give you all the details you need.
