Sepura Contributes to Success of World’s First Cross-border TETRA System

We take it for granted that when we move around the country our mobile phones connect to the nearest mast, or we go abroad and our phones automatically connect to the network, with tetra, this is not as easy, but this article is about a test that Sepura completed connecting two TETRA networks in Norway and Sweden, interesting stuff.

Sepura radios have successfully participated in interoperability trials for the world’s first cross-border TETRA communication system, linking RAKEL and Nødnett, Sweden and Norway’s public safety networks.

More than 350 first responders were involved in the trials, which took place in Meråker, close to the Swedish border, in a crisis response exercise involving public safety users from both countries.

The cross-border system utilises TETRA Inter-System Interface (ISI) functionality to connect networks together, effectively allowing users to roam to another network. This allows first responders to use their radios in both countries – vital for smooth collaboration in emergency situations.

The initiative to strengthen co-operation between national emergency services started in 2013 with the EU-funded Inter-System Interoperability project, designed to improve the ability to respond to natural disasters and security threats. The RAKEL and Nødnett networks are scheduled to be ready for bi-national operational use in early 2017.

Sepura’s STP9000 hand-portable radios and SRG3900 mobile radios were used by both Swedish and Norwegian emergency services during the exercise, although all Sepura radios – including the new flagship SC20 range – meet the technical requirements of the ISI system.

“This is one of the most advanced multinational radio communication projects in Europe,” said Tariq Haque, Product Manager for Sepura.

“After two years’ development, bi-national interoperability has become a reality, bringing cross-border mission critical communications to Sweden and Norway.

“We are extremely pleased to have played a part in this ground-breaking event.”

Hytera Awarded Multi Million Dollar Contracts in Dominican Republic

Hytera are the fastest growing radio country this year, they have opened offices all over the world and are taking market share from Motorola. When you look at their Hytera radio earpieces, Chargers, repeaters, hand portables and base units they are of an excellent standard and quality. That is probably why the Dominican Republic was persuaded to use them for two big projects.

Hytera, a world leading solution provider of Professional Mobile Radio communications, was awarded two projects by the Ministry of the Presidency of Dominican Republic. In order to establish a nationwide emergency response network for National Emergency Care System and Security 9-1-1 (Sistema Nacional de Atención a Emergencias y Seguridad), Dominican Republic government selected TETRA (Terrestrial Trunked Radio) technology for mission critical communications, and launched two public tenders at the end of 2015; one is to cover two cities, Haina and San Cristobal, adjacent to the capital city Santo Domingo, with 5 sites and 528 terminals, while the other is to cover Santiago, the second largest city of the country, with 30 sites and 2,155 terminals.

The existing TETRA network in the Santo Domingo area was delivered also by Hytera as a result of a contract awarded by Dominican Republic’s Ministry of the Presidency in 2013. The project includes several components: the 911 system, a camera surveillance system and the communications infrastructure with its respective terminals which was awarded to Hytera. “The system in Santo Domingo offers reliable communication services to the public safety forces, and it is a very good testimony of Hytera’s solutions and supports,” said Fernando Camelo, regional director of Hytera international business.

“Dominican Republic government officials have spent a lot effort to choose the right technologies for its public safety forces. Obviously, TETRA has been widely adopted and proved. We are proud to be part of the initiative of building a united nationwide mission critical communication system for the country,” commented Ming Kam Wong, deputy general manager of Hytera international business.

The TETRA digital standard as a global open protocol provides secure, encrypted communications for mission critical operations as well as promoting a more efficient use of spectrum. More than 750 interoperability (IOP) certificates have been awarded to more than two dozen manufacturers by the TETRA + Critical Communications Association (TCCA), the governing body, globally, for the TETRA standard.

5 Examples of Earpiece to Hear Far Away

1. Using a Mobile Phone And Bluetooth headsets or Earpiece

To do this, you simply need to go into your mobile phone’s settings and then change answering mode to Auto; this enables your phone to answer automatically when you ring it. Most mobile phones only work in the Auto answer mode, after you have plugged in the headset.

After turning on the Bluetooth headset, make sure it’s properly paired with your cell phone, and confirm the battery has adequate charge. Hide your Bluetooth headset somewhere you know it’ll pick up the sounds clearly, however, make sure that it’s well hidden.

Leave the room, however, do not go very far. The Bluetooth connection will work through the walls, but if you happen to go far away, it’ll not work very well (the range can be up to about 30 feet or 3 rooms away). Now test your cell phone by calling it to see how far you can actually go and still get to hear the bugged room through the Bluetooth headset.

You can wait for the conversations to get to the interesting part, and then turn on voice recorder on the cell phone; it should be able to record via the microphone of your Bluetooth headset.

2. Using a Two Way Radio and Earpiece

Two way radios allow users to communicate when they’re far away such that they can not hear each other. These devices use radio frequencies instead of cell phone towers which means they will work in areas where there’s no cell phone coverage or reception.

The two way radios offer instantaneous communication; users simply need to press the Push-To-Talk (also known as PTT) key, and they can instantly talk and convey their particular message to the other party. This is due to the quick call setup time that’s entrenched in this technology. The ability to offer quick communications is one of the reasons why most organizations prefer the two way radios for their tactical and operational communications.

Another great feature of the two way radios, is the ability to facilitate one to many (also known as, group calls) communications effectively. This basically means that a single user can conveniently communicate with 2, 10, 20, and more, of other two way radio users at the same time. In short, there is no need for you to repeat time and time again when you want to communicate with many people and using a two way radio earpiece, this communication is much more secure

3. Ear Spy Application

Ear Spy App is a great eavesdropping tool. Depending on just how good your cell phone is, this app can become a very high powered listening tool. Ear Spy application can route the audio from your cell phone’s mic right to to your headset letting you eavesdrop on the people around you whilst remaining inconspicuous. When using a Bluetooth, you can use this app to spy from a room nearby; you simply need to leave your cell phone near the target, and then use your Bluetooth headset to eavesdrop. If you want to fine tune the incoming signals, you can use the graphics audio equalizer. Whether you wish to eavesdrop on particular conversations or you just want to play some spy games, Ear Spy application will be of great help in your endeavor. You should know that this app requires you to use headphones, otherwise you will get poor audio feedback.

4. Spy Glasses

This spy device comprises of an in built Bluetooth transmitter which looks like ordinary glasses, a microphone and a wireless earpiece. Connections between the glasses, the earpiece and your cell phone are wireless, thus totally unnoticeable to other people; the device’s ultra compact design basically ensures nobody will know it is a spy tool. Spy glasses are compatible with almost any mobile phone which has the Bluetooth option. Actually, the Spy glasses are universally compatible with all the standard Bluetooth enabled equipment including computers. Some of the features of this device include; excellent transmission and reception of audio signals, built in microphone, and a large capacity Lithium battery.

5. Micro Air Vehicles (MAVs)

Modern technological advances are ever increasing human’s potential for developing tiny things. As for the United States Air Force, this translates to revolutionary designs in the air vehicles to provide the war fighters with new tools which can enhance both the situational awareness, and also the capacity of engaging quickly, accurately, and with minimal collateral damage. This is where Micro Air Vehicles (also known as MAVs) come in. The term MAV or micro air vehicle, refers to the a new type of advanced remotely controlled aircraft (abbreviated as, UAV) that’s significantly much smaller than other similar aircraft. Typically, MAVs can easily blend in with the surrounding environment, stay in air for a long period of time, and can go places which can’t be reached safely by humans, or most of the other types surveillance equipment.

The target dimensions for MAVs is approximately 6 inches (15 centimeters), and the development of actual insect sized aircrafts is expected in near future. As a matter of fact, various efforts in the research on micro air vehicles have involved attempting to mimic flying insects so as to achieve the flight capabilities which aren’t attainable through the use of other means of aerial propulsion. In the year 2007, a bug like Micro air vehicle model with a wingspan of 3 cm was revealed at a robotic’s conference; in the year 2008, the United States Air Force released a video showing Micro air vehicles which were the size of a bumblebee; and in the year 2012, some engineers from Johns Hopkins University started studying flight of butterflies to discover how airborne robots can mimic their maneuvers.

The potential military use is 1 of the key driving factors, although the micro air vehicle can also be used commercially, as well as in scientific and mapping applications. The main military use envisioned for the micro air vehicle is gathering of intelligence via the use of microphones, cameras, or other types of sensor.

Conclusion

Some of the above points are illegal, and you should not do any of them. Also, do not use any of the above methods to record any intimate relations; the legal consequences of doing so are very severe. Finally, keep in mind that it’s illegal in the US to make recordings of people without their consent/permission; and depending on what you’ll do with the recordings, you might find yourself in big trouble.

Why 2 Way Radio is ideal for Business

Effective communication is crucial to the success of any business. Poor communication can easily lead to the collapse of any business regardless of size. If you’re running a huge business where keeping in touch with your staff is important, then you must put in place a very efficient communication system. A system that is not only efficient but also cost effective. These two factors are the reason 2 way radios are popular with modern businesses. A 2 way radio is a communication device that can both transmit and receive signal. It allows users using the same frequency to have a conversation at minimal or zero cost.

Why you should consider using a 2 way radio for your business

There are numerous benefits that a business will enjoy by making a 2 way radio its choice of communication. First, the radio provides a platform where you can conveniently keep in touch with your staff anytime you want. If you are the manager and the firm has several departments where you cannot physically access the staff, then this is the perfect device for you. Second, it’s easy to manage, unlike mobile phones that rely on the service providers. With radio system, you manage it from your premises.

The fact that a 2 way radio can only receive and send information at a set frequency improves your business’ safety. You can keep the frequency a secret such that only certified individuals can access crucial information. The radio also allows you to create several channels for specific groups. This option allows you to call individual groups whenever the need arises. For example, if the information is meant for security department, it will not be necessary to have it broadcasted to other groups.

Its broad geographical coverage is another reason you should have this communication gadget. If your business Covers a vast geographic area such as a farm or a construction site, this is the perfect mode of communication to employ. It can also be an effective security monitoring system if it’s well managed and utilized. Combining this system with GPS and the CCTV can significantly improve matters of security for your business.

But who can use the 2 way radio system?

A 2 way radio is one of the most user friend and flexible communication gadgets. Any firm can use it regardless of size. The radio is indeed the perfect model for a business that is struggling with geographical coverage challenges. It is ideal for shift workers, security staff, production line inspectors, farm workers, construction sites, shop watch and the list is endless. Anyone can use it. It only requires a little bit training on how to receive or to send a signal, and the user will be good to go.

Advantages of 2 way radios

One thing that stands out from this system is the reduced cost of communication- the cost is almost zero-rated compared to the other systems such as mobile phones. A 2 way radio is also very simple to use since you simply press the button to start talking. This speed can be crucial in cases of emergency compared to mobile phones where you will be needed to dial several buttons to make a call.

With this radio system, you can talk to multiple users at once- this is not possible with mobile phones. The gadget is built to military specs -the radio can be used in wet conditions and can withstand even a drop on the concrete surface. 2 way radio is one of the devices that can work in all areas of your business where mobile phones don’t work. The last but not the list of the advantage is that the radio stays on site, and thus different shifts can conveniently share it.

Key questions before installing a 2 way radio system

There are several questions that you must get clear answers to before you install a 2 way radio system. First, the area that the radio system is going to be used must be known. This will determine the power of the transmitter needed to cover that area. The number of people projected to use the radios should be the next question. The answer gives the number of radios required. The last question should be your budget. You must purchase what you can afford without compromising on the quality. With these questions answered, then you can have the most efficient 2 way radio communication system for your business.

How Many Walkie-Talkies Can Operate on the Same Channel?

Theoretically, you can use an unlimited amount of walkie-talkies on the same channel (although in practice you might experience a few problems if you took that suggestion literally). Basically, there isn’t really a set limit. You could use as many as you like provided they are set up correctly. Anybody set to the right channel and in range at the time of transmission would then be able to pick up the signal and respond to it.

Most radios have access to 8 channels. These channels each have 38 separate ‘identification tones’. The user sets his/her channel up with the desired tone and then only other users who know the channel/tone will be able to hear the transmissions. As a result, there are, in any given area, about 304 different combinations, so signal interference is unlikely to affect you.

Please do not interpret this answer as saying that your radio has access to 304 possible channels. It does not. It will likely only have access to 8. Some less reputable manufacturers tend to falsely imply access to 304 channels; this is simply not the case. You will have access to 304 possible tone/channel combinations, that’s all.

To better explain the CTCSS codes and how they work; we’ll include a little information from Amherst.co.uk’s FAQ page.

“CTCSS stands for “Continuous Tone Coded Squelch System”. These codes are also often called “Privacy codes” If a CTCSS tone is selected; a CTCSS sub-audible tone is transmitted along with the regular voice audio by the transmitting radio. The receiving radio, set to the same CTCSS tone, will only receive audio if it contains that sub-tone. Interference from other users on the same frequency is therefore rejected (unless they are also on the same sub-tone). This is a way of allowing groups of users of walkie-talkies on the same channel to avoid hearing messages from other nearby users”.

So, in conclusion, you can probably use as many walkie-talkies as you like on the same channel. As long as the units in question are of the same type (either VHF or UHF) and have the same CTCSS setup, then you simply shouldn’t have a problem. You also shouldn’t suffer from signal interference due to other users (although you may still experience signal loss/interference/degradation from other sources). We have talked about combating signal loss elsewhere, so please see the other questions if you have any problems in this area.

Where Is It Possible To Buy a Great Two Way Radio?

If you’re planning a family outing where you’ll camp for several days, or if you’re headed for an amusement packed backpacking expedition with friends, you might want to know where to buy walkie talkie communication systems. These gadgets are very small in size, and you can go with them wherever you want to as most of them weigh less than half a pound and you can hardly feel burdened by them as you hike.

Additionally, they come in very handy in regions where cell phones cannot dare venture. Some top quality walkie talkies can provide a huge array of features such as weather alerts as well as SOS signals. 2wayradionline has all kinds of two-way radios including the newest types that come with better-quality frequency options as well as radio ranges.

Types of two-way radios

Bearing in mind that there’s a myriad of two-way radio systems available in the market, arguably the most important question to ask yourself if you want to buy a walkie talkie is: what’s the best choice? However, this isn’t a very hard decision once you understand where and how you’ll use it. Firstly, you’ll need to pick either of the two main kinds of two-way radios, which are family or consumer walkie talkies and professional business walkie talkies.

Within both kinds, you would also want to decide whether a radio system with licensed or unlicensed band is most suitable for you. On the one hand, licensed radios come with powerful 5W frequency transmissions and a wider coverage range. However, you’ll have to be contented with a frequency fee. On the other hand, unlicensed band walkie talkies attract no fees, but they’re comparatively low in power plus a limited range that’s only suitable for casual users.

You would also want to decide between an analogue and a digital walkie talkie. Some businesses search for radio systems that can operate suitably in risky highly explosive environments. Radios with ATEX certification are highly recommended in such areas. You can find all these kinds of walkie talkies and more at 2wayradionline

VHF or UHF walkie talkies?

An important consideration when looking to buy walkie talkie is keeping in mind that Ultra High Frequency (UHF) radios will be your best purchase in most cases. Essentially, a UHF radio can never send or receive communication to a Very High Frequency (VHF) radio. As such, if you have some walkie talkies and you’re only looking to add some more units to be used with what you already have, go for the same band.

VHF radios can provide more coverage with less power, but they only function well when there’s little interference between the sender and the receiver. UHF walkie talkies function best with most users since they have shorter waves and can penetrate or get around areas of interference such as hilly areas, thickly wooded areas, in buildings as well as in urban outdoor settings. If you’ll use your radios strictly indoors or if it’s a combination of indoors and outdoors, then UHF is the best choice. You can choose from some of the best VHF and UHF two-way radios at 2wayradionline.co.uk

Earpiece For Secret Service: 5 Key Points

When you think of the US Secret Service agents, the image that comes to mind is that of a person in dark sunglasses, black suit, and a coiled tube thing goes into his ear. The coiled tube thing is what the agents use to monitor and communicate what’s going around them, where dangers lurk and where they’re are needed. Unfortunately, the coiled tube thing tends to be very noticeable such that the bad guys will easily identify the secret service agents. Over the past couple of years, various earpiece companies have closely worked with the US secret service, and have supplied the agents with quality covert tactical earpieces. The covert tactical earpieces are much better than the traditional coiled tube earpieces because of a number of reasons. Some of the reasons include;

1. Discreetness/Covertness

Security professionals typically chose earpieces based on just how discrete/covert they want to be. The level of covertness or discreetness is usually determined by the type of earpiece, earpiece style, and also the color. As aforementioned, if you want to identify a secret service agent you can simply look for the guy with a coiled tube type of earpiece. Luckily for secret service agents, various earpiece companies now offer earpieces which allow the secret service agents to efficiently communicate in a more covert and discreet manner without anybody noticing. They allow for discreet communication between the agent and his or her team.

In-ear earpieces are typically more discreet because they’re worn inside of the the ear as compared to the over-the-ear earpieces which are worn outside of the ear. It is also wiser to opt for colourless earpieces as opposed to the coloured earpieces for extra covertness. You can also opt for the wireless earpieces; the wireless earpieces are usually preferred over the wired earpieces since it is hard to tell that somebody is actually wearing the wireless earpiece as compared to the coiled tube, wired earpieces. The wireless earpieces normally receive the signals wireless. One needs to have a separate microphone worn at the end of the sleeve, or even on a lapel. In order to send a message to the other(s), the wearer has to speak into that microphone, and the other(s) will receive the message via their wireless earpieces.

2. Comfort

You should obviously choose an earpiece which is comfortable to wear ; Some of the crucial questions to ask prior to choosing an earpiece can include; how easy that earpiece is to not only wear, but also to remove, how easy is it to control and use the earpiece, and also whether the earpiece will be able to remain intact for as long as needed without falling off. One of the main reasons why most people dislike the coiled tube earpieces, is the lack of comfort. Most agents say that the coiled tube earpieces cause a lot of ear fatigue. Most of the secret service agents are usually connected to the radio 12 to 16 hours per day, and some agents will have the earpieces draped over their ears and hanging out, with the volume of their radio turned way up so they do not have to have to plug the coiled tube earpiece in their ears all day long. . Fortunately, the covert/discreet earpieces are very comfortable to wear. They use speakers which are smaller than the average ear canal; this means that there’s very little contact, thus are ideal for secret service agents who want to avoid the feeling of ear fatigue.

3. Sound quality

Secret service agents are dealt with protecting the President and as such, it is crucial to get everything right, including the message being sent to their earpiece. In case of a sensitive situation, it is even more crucial to get the message right or correctly. Listening to sounds which are being pushed up a coiled tube may leave a margin for error. The tactical earpieces have the speakers placed in the canal of the ear which means that the sound is basically created there, (approximately 7millimeters from the eardrum), and is worn in both of the ears. This allows the wearer to clearly listen to what’s being transmitted through the earpiece, meaning they will be more efficient in their work.

4. Volume

This is one of the main reasons why secret service agents dislike their coiled tube earpieces. Many of the secret service agents say that they usually feel like they are gradually incurring hearing loss especially in the ear which they plug the radio earpiece. Well, with the covert earpieces, the ear isn’t plugged so that the sound pressure can get released. And since it’s worn in both of the ears, and the speakers are located in the ear, the radio may be turned down, and you will have much better sound clarity. This allows agents to work more efficiently, and in addition, they will have no fear of incurring hearing loss.

5. Localization

The brain is typically wired to locate where sounds/noises originate from, or rather the brain is wired to localize. When you hear a sound from the right side, you will know it since it enters your right ear a little louder and a little quicker, and your brain registers that the sound came from the right direction. This means that a secret service agent, or anybody wearing the coiled tube type of earpiece in their right ear, might hear a similar sound a little louder in their left ear since their right ear is plugged. In sensitive situations, mistaking the location of the sound can be disastrous since it could leave time for bad guys to get away, attack, or complete their objective. The tactical earpieces are designed such that they help the secret service agents to accurately locate the actual place the sound is originating from.

Conclusion

The covert earpieces address all negative issues which anybody who wears or uses the coiled tube type of earpiece experiences. They’re comfortable, discreet, they use top notch, high end, high quality speakers which offer the best clarity, they help in reducing the risk of future hearing loss since one can reduce/adjust the radio volume, and they also allow wearers to accurately and quickly localize the direction a sound is coming from.

Musician sues Royal Opera House over ruined hearing

It is quite a common thing that musicians and artists that are exposed to loud noise, will eventually suffer from hearing damage. We have seen many artists suffer from this career threatening damage, the likes of Phil Collins, Eric Clapton and Ozzy Osbourne and the tinnitus that is effecting Chris Martin from Coldplay, this is a problem that many more will be affected by. This article from the BBC talks about Chris Goldscheider and his pursuit of damages over his hearing damage. Rightly or wrongly it’s an interesting tale.

A renowned viola player is suing the Royal Opera House for ruining his hearing and his career during rehearsals of Wagner’s Die Walkure.

Chris Goldscheider claims his hearing was irreversibly damaged by brass instruments put immediately behind him.

The Musicians’ Union says hearing damage is a major problem for musicians playing in orchestras.

The Royal Opera House denies it is responsible, but around a quarter of its players suffer hearing illnesses.

In court documents seen by the BBC, Goldscheider claims that in 2012 his hearing was “irreversibly damaged” during rehearsals of Richard Wagner’s thunderous Die Walkure “from brass instruments placed immediately behind him” in the famous “pit” at the Royal Opera House.

The sound peaked at around 137 decibels, which is roughly the sound of a jet engine. The court documents say the noise “created an immediate and permanent traumatic threshold shift”.

Image captionChris Goldscheider played the viola with some of the world’s greatest orchestras

Goldscheider says this amounts to “acoustic shock”, one effect of which is that the brain hugely amplifies ordinary sounds.

Music has been in most of Goldscheider’s life: “For the last quarter of a century I’ve been a professional musician. Music was my income. It was my everything,” he says.

The son of a composer, from the age of 10 he spent in excess of six hours a day practising and rehearsing. He played the viola with the Royal Liverpool Philharmonic and BBC Symphony orchestras, before joining the prestigious Royal Opera House orchestra in 2002.

_2009.jpg” width=”292″ />

Career highlights have included performing live with the famous Three Tenors to 100,000 people at the Barcelona Camp Nou football stadium, and with Kylie Minogue on MTV. He has also recorded with artists including the band 10cc.

Goldscheider says the effects of the hearing damage have been devastating.

“Ordinary sounds like banging cups and glasses together is a very painful noise,” he says.

“My newborn daughter last year was crying so much I actually got noise-induced vertigo because of my injury and I ended up in bed for three weeks.”

The musician says he has lost the career he loved and his mental health has deteriorated as he struggles to cope with the impact and effects of his hearing problems.

Life has changed dramatically. To carry out ordinary every day tasks such as preparing food, Chris has to wear ear protectors. Especially upsetting is that he had been unable to listen to his 18-year-old son Ben – one of the country’s outstanding young French horn players.

“Ben is a fantastic musician. I haven’t been able to listen to him play or practice since my injury. I’ve missed him playing concerts and winning competitions. I can’t even bear him practising in an upstairs room when I am downstairs in the house,” he says.

musician has to wear ear protectors to carry out every day tasks

At the time of his injury, Goldscheider was provided with hearing protection capable of reducing the noise by up to 28 decibels, but his lawyers claim this was insufficient. They say he was not given enough training in how to use it and protect himself, and that the noise levels should not have been so dangerously high.

The Royal Opera House does not accept the rehearsal noise caused Goldscheider’s injury, and denies that is responsible.

In a statement it told the BBC: “Mr Goldscheider’s compensation claim against the Royal Opera House is a complex medico-legal issue, which has been going on for some time and is still under investigation.

“All sides are keen to reach a resolution. The matter is now the subject of legal proceedings, and in the circumstances it wouldn’t be appropriate to comment any further at this stage.”

And according to Goldscheider’s solicitor Chris Fry, part of the Royal Opera House’s defence breaks new legal ground.

“Essentially what is being said is that the beautiful artistic output justifies damaging the hearing of the musicians performing it,” he says.

“That’s never been tested by the courts. We don’t think the court is likely to uphold that, in particular where it’s clear steps could be taken to maintain the beautiful sound and protect hearing at the same time.”

he Royal Opera House denies it is responsible for Chris Goldscheider’s hearing issue

Hearing damage suffered by rock musicians is well documented. Years ago The Who’s Pete Townsend went public about his hearing loss and famously said a doctor had told him: “You’re not actually going deaf, but I’d advise you to learn to lip read.”

Brian Johnson of AC/DC and Ozzy Osborne have also been affected. But what is far less well known is that it is a significant problem in the more sedate and sophisticated world of classical music.

There are around 100 players in the orchestra at the Royal Opera House. The BBC has learnt more than a quarter report occasional or mild hearing illness, and that in the 2013/14 season, there were seven cases of sickness absence related to noise problems and a total of 117 weeks of sick leave taken. That’s not music to anyone’s ears.

Morris Stemp of the Musicians Union says there are many reasons for the hearing damage suffered by classical musicians.

“Conductors are allowed to ride roughshod over health and safety considerations,” he says. “They put players on the stage where they will be in harm’s way. And instruments are now louder than they ever were before because of the materials they are now made from.”

Add to that the increased number of live concerts prompted in part by the drop in income from CD sales, and there is a mix of elements that can put the hearing of orchestra players at serious risk.

Chris Goldscheider’s case casts light on a little known or discussed problem, and will be watched closely by all those in the classical music world.

 

Public Safety Radio Network encounters Capacity Challenges during Brussels Bombings – See more at: http://www.tetra-applications.com/32377/news/public-safety-radio-network-encounters-capacity-challenges-during-brussels-bombings#sthash.cekBZicn.E8LGoeNh.dpuf

This article is from the well trusted tetra-applications.com website This story is about the Belgian tetra system, called ASTRID, running close to full capacity during one of the biggest disaster events that Belgium has seen. The system had a few stuttering moments, but with the unpredictable surge in traffic after the event, this is to be expected. To learn more read below and see what they are planning to do…..

During last week bombings, ASTRID, the Belgian Public Safety TETRA network encountered a huge increase of traffic which resulted in a temporarily capacity problem.

ASTRID, the TETRA radio communications network in Belgium, used by the security forces, has not functioned as desired, after the attacks of last week Tuesday, several media announced. Also the GSM network was down and therefore in some cases WhatsApp had to be used by the security forces.

Commissioner General Catherine De Bolle has requested an investigation. Several media mentioned that for many hours the system would not have worked. Therefore, the rescue operations of the police at the airport were much more difficult and more chaotic than it should be. Spokesman Peter Dewaele of the federal police admits that some things did not run as planned.

Astrid responds

“After analyzing the situation, Astrid requested all user organizations to sit around the table in order to examine the communication after the attacks of 22 March. Meanwhile, concrete action and specific recommendations were specified,”

According to ASTRID, the exceptional nature of the emergency caused that some masts of the radio network could not be reached for a short period of time, because of the enormous increased traffic. Therefore communication was not possible, Astrid announced.

“From across the country emergency and security services were asked to provide assistance, which led to an extraordinary radio traffic. On specific requests of many of these organizations Astrid registered hundreds of extra radios to the network. Also the failure commercial mobile phone networks has led to a significant increase in radio traffic.”

“Not flat, or capacity”

Astrid points out that the control rooms/emergency centers were particularly busy in Brussels and Flemish Brabant, but they continue to function properly. Also the alarm system for calling the volunteer fire brigade received extra traffic, but the system worked without any problem. Astrid also installed a mobile-transmission tower in order to strengthen the radio network in the Brussels area.

On a nationwide level, the radio network was still operational, but especially in the Brussels region there were severe capacity challenges,” Astrid notes. “Shortly after the attacks the nearby Astrid masts reached their maximum output, which resulted in difficult communication during some crucial hours. Some users had no access to their talk groups.”

“On Friday March 25th we discussed the situation with the End User Advisory Committee. Concrete action points and recommendations for the use of the radio network and training were determined,” concludes Astrid.
