We are seeing a new era in communications at the moment, the move from tetra and RF to the mobile network. The ukâs emergency services will be moved over to EEâs ESN system slowly until 2020 using Motorola kit designed particularly for the technology. The natural evolution is 5G, which we wonât see for many years, but Ericsson have taken the baton and are running with it.
Ericsson (NASDAQ:ERIC) is commercializing the world’s first 5G NR radio for massive MIMO, with the first deployments coming in 2017. Together with the Ericsson 5G Plug-Ins announced in June and Ericsson’s already commercially available Radio System Baseband 5216, which currently powers Ericsson’s award-winning Radio Test Bed, Ericsson is first to deliver all components of a 5G access network.
Tom Keathley, senior vice president, Wireless Network Architecture and Design, AT&T, says: “As we accelerate toward 5G, it’s beneficial to have a flexible radio platform that can be deployed not only for LTE, but also versions of future 5G NR standards.”
AIR 6468 combines advanced antennas with a large number of steerable ports to enable 5G technologies of beamforming, Massive MIMO and — building on that — Multi-user MIMO, initialized as MU-MIMO. These capabilities improve user experience while enhancing the capacity and coverage of the network and reducing interference. The new radio provides LTE support as well, so it is applicable in today’s networks.
Huang Yuhong, Deputy Head, China Mobile Research Institute (CMRI), says: “Massive-MIMO, also known as 3D MIMO, is an important milestone in China Mobile’s technology roadmap from 4G to 5G. We are very happy that Ericsson’s new radio product is coming to market soon to meet our needs and enable us to integrate 5G technologies into our existing networks.”
A host of new additions to the Ericsson Radio System are also coming that address key 5G requirements, in today’s networks.
Daniel Staub, Head of Joint Mobile Group, Swisscom, says: “On the road to 5G, we will continue to invest in LTE advancements that will become part of our 5G networks. For us, it is key that Ericsson has chosen to focus on advances that will support us in this evolution. These enhancements will further improve the customer experience.”
Additional new Ericsson Radio System gear addresses 5G concepts
Peter Jarich, Vice President, Consumer and Infrastructure Services, Current Analysis, says: “Mobile operators, today, are clearly focused on the race to 5G commercialization, while also continuing to invest in their existing LTE networks. With a new 5G radio and LTE offerings which echo key 5G concepts – small cells, licensed-unlicensed band combinations, Cloud RAN, network densification, spectrum optimization – Ericsson’s new portfolio additions and Ericsson Radio System innovations provide a compelling way forward.”
To support new network builds, Ericsson has created the industry’s first Industrialized Network Rollout Services solution. The Network Deployment Delivery Platform coupled with Ericsson’s pioneering process facilitates the complete configuration, installation, integration, shakedown and handover of a fully verified site, ready in a single site visit.
Arun Bansal, Head of Business Unit Network Products, Ericsson, says: “Ericsson has driven innovation in every generation of mobile technology and now we are set to over-deliver on an aggressive promise. We are introducing the new hardware that 5G Plug-Ins, announced in June, will run on, so that the first operators can start to deploy 5G infrastructure.Â And, we are also launching innovations that improve both the performance and efficiency of today’s networks using concepts that will evolve into 5G.”

The good old walkie talkie will still have a place in most businesses, but Motorola being a technology company they are always innovating, they are underpinning their future communications on data, currently date networks cannot cope with this but as the technology grows, Motorola will be able to produce handsets, motorola accessories and communications that will seamlessly use this without any problem, we look forward to the future.Â
Motorola Solutions CTO Paul Steinberg explains how data and enhanced communications can make cities safer â even if theyâre not smart just yet
As CTO of Motorola Solutions (MSI), Paul Steinberg says he has three broad remits.
The first is to advance the companyâs technology with his team of engineers and data scientists, the second is to drive its patent strategy (âWhat patents we get and what we do with themâ) and the third is to invest in startups so MSI can get access to something it doesnât have.
âIt keeps you humble because thereâs always someone else doing things faster and better than you,â he tellsÂ TechWeekEurope.
Motorola Solutions now only deals with public safety communications systems. It was spun off from the Motorola Mobility handset business that was sold to Google (and later Lenovo) in 2011 and sold itsÂ handheld computing division to Zebra Technologies in 2014.
This might seem like a very narrow focus but itâs a market in which the present day Motorola senses a great opportunity as emergency services update their infrastructure to improve service and cut cost.
In the UK, MSI is working withÂ EE to help deliver the Â£1 billion Emergency Services Network (ESN) â a 4G platform that will allow for data-enabled services alongside critical communications â and save the government Â£1 million a day
These upgrades will power what MSI sees as the big trend in public safety: the coupling of communications with data analytics, a vision it recently outlined at Critical Communications World (CCW) in Amsterdam.
â[Mission critical communications are] every bit as important as they have been and we expect [them] to be tomorrow,â explains Steinberg.
âMission critical intelligence brings in connecting things â data. It becomes more about context and situational awareness. The investments weâre making are more in that direction.
âOne of the things weâve been working on is the connected first responder. What we did was we built a context engine thatâs at the heart.â
The âcontext engineâ built by MSI brings together various different inputs. For example, Bluetooth connectivity can unite weapons, body sensors and imaging equipment to give a police force a greater overview of a situation.
Steinberg explains a scenario where if the context engine detects a weapon has been fired and a policeman is not at a station or at a firing range, their video camera will automatically switch on. Other situations could give a paramedic of firefighter additional information, possibly through wearable technology.
âWhy did we do the Context engine? âEyes open, hands freeâ: keep focussed on what youâre doing and keep your hands available to do what you need to do,â saidÂ Steinberg.
âWe envisage this working as an ecosystem with well-designed interfaces around the core context engine. We see ecosystem partners offering applications and hardware. And some pieces of those we will offer as Motorola. We see it increasingly as a software problem.â
Steinberg favours acquisitions as a way of advancing his goals and MSI has venture capital operations to fund the third part of his remit. MSI monitors the development of numerous early stage companies with a view to boosting its own business.
â[Takeovers] give us technology or a skillset that we canât do properly [ourselves],â he explains. âIf the concept looks like it has legs, thatâs when we make the decision. In some cases we donât proceed.â
Sometimes the target is more established.Â MSI has bought Airwave for Â£817 million, a move which it is believed will help accelerate the transition to next generation systems. Airwave currently powers the pre-ESN communications capability of the UK emergency services and Steinberg sees the acquisition as a method to migrate customers rather than innovate.
âIt brings us another data point but it doesnât really change how my team works,â he says. âItâs a company that helps us ensure we have an orderly migration.â
Smart cities and smart vehicles
MSI says the Context Engine and its vision of data-supported communications will be strengthened by theÂ parallel development of smart cities;Â even if itâs too early to have any impact right now. Steinberg describes âshotspotterâ technology capable of detecting when and where a gunshot is fired, aiding emergency services, and believes smart cars will also play a role.
âI think as the city becomes smarter, we can benefit from the environment,â he predicts. âWe can fuse that together and help facilitate real time decision making. The next mobile platform is the vehicle. I think that will create some interesting opportunities for us.â
But the very nature of emergency services means technological jumps are not to be taken lightly. A technical hiccup can mean the matter between life and death and although political reasons might have delayed the transition to LTE, concerns about reliability will have played a role too.
Steinberg agrees and is adamant that no matter what advances are made, MSI will not jeopardise the basics.
âThe foundation of our business is communications and it always will be,â he states. âMaking sure our platform is resilient, usable and mission critical in harsh environments while layering on this intelligence.â
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 bandâs and the singerâs 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.
Back in December the UK government decided on who and what will drive the new generation of emergency service communications. The ESN (Emergency Services Network) was the result of months of tendering and negotiations. So they decided that EE would manage the network and Motorola would provide the hardware. This article is about the first wave of communication devices that Motorola are planning to use with the ESN.
New innovative solution combines body-worn video camera, radio speaker and microphone with cloud-based data storage and management to create a complete digital evidence management system
At Critical Communications World 2016 (May 31 to June 2 in Amsterdam), Motorola Solutions announces a new combination of body-worn video camera, radio speaker and microphone, along with new, cloud-based, digital evidence management software, which is able to collaborate with TETRA digital two-way radios. The new âSmart Interfaceâ (Si) Si500 Video Speaker Microphone (VSM) is reducing the number of devices that weigh down public safety officers in the field today, while CommandCentral Vault digital evidence management software is providing unparalleled efficiency that saves time and resources.
Public safety agencies today face an increasing demand to capture, store, properly manage and share video evidence. While use of body-worn cameras has widespread and growing acceptance with public safety agencies and the citizens they protect, the massive amounts of data cameras create needs to be managed and stored, oftentimes incurring significant costs. With its new solution, Motorola Solutions tackles all of these challenges and offers an end-to-end solution that can be used with existing TETRA radio equipment. Public safety agencies are provided with a seamless experience from video capture in the field to back office storage and content management that helps them simplify workflows and reduce administrative overheads.
âIn Europe Middle East and Africa (EMEA), TETRA digital radio technology has become a standard for mission-critical communications,â said Steven Young, vice president TETRA devices at Motorola Solutions. âThis is why we have developed a body-worn video solution that collaborates with TETRA radios. The Si500 is transforming digital evidence management by integrating our best microphone into a body-worn camera and combining it with a content management system thatÂ´s unmatched in its ease-of-use.â
Sight and Sound Simplified
Both body-worn camera and remote radio speaker microphone, the compact Si500 VSM is a unique interface that extends the mission-critical performance of Motorola Solutions TETRA digital two-way radios. The lightweight compact design includes innovative features to meet the needs of first responders:
Integrated Wi-Fi dramatically improves the speed of uploading multi-media. It also makes over-the-air feature updates via Radio Management quickly and seamlessly over Wi-Fi.
Digital Evidence Management Revolutionized
The digital evidence management solution includes the cloud-based CommandCentral Vault software application to securely store, manage and share digital evidence. With an expansive base storage capacity and integration with computer aided dispatch and records management systems, CommandCentral Vault is designed to make digital evidence management easy and affordable. The digital evidence management software also:
Pairs with the Si500 VSM and can also operate stand alone and accept evidence gathered from any device
Itâs 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 RÃo de Janeiro State in Brazil to supply communications for the Summer Olympics and Paralympics, informally known as Rio 2016.
The â¬10m contract will cover four venues (Barra da Tijuca, Copacabana, Deodoro and MaracanÃ£), two airports (Rio de Janeiro/GaleÃ£o – AntÃ´nio 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.”
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 itâs an interesting tale.
A renowned viola player is suing the Royal Opera House for ruining his hearing and his career during rehearsals of Wagnerâs Die Walkure.
Chris Goldscheider claims his hearing was irreversibly damaged by brass instruments put immediately behind him.
The Musiciansâ 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 Wagnerâs 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”.

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 Goldscheiderâs life: “For the last quarter of a century Iâve 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.
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 countryâs outstanding young French horn players.
“Ben is a fantastic musician. I havenât been able to listen to him play or practice since my injury. Iâve missed him playing concerts and winning competitions. I canât 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 Goldscheiderâs injury, and denies that is responsible.
In a statement it told the BBC: “Mr Goldscheiderâs 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 wouldnât be appropriate to comment any further at this stage.”
And according to Goldscheiderâs solicitor Chris Fry, part of the Royal Opera Houseâs 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.
“Thatâs never been tested by the courts. We donât think the court is likely to uphold that, in particular where itâs clear steps could be taken to maintain the beautiful sound and protect hearing at the same time.”

Hearing damage suffered by rock musicians is well documented. Years ago The Whoâs Pete Townsend went public about his hearing loss and famously said a doctor had told him: “Youâre not actually going deaf, but Iâd 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. Thatâs not music to anyoneâs 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 harmâs 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 Goldscheiderâs case casts light on a little known or discussed problem, and will be watched closely by all those in the classical music world.
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 âcan headphones make you deaf?â
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 âlearning.
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.
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 doesnât happen overnight. Your ear will warn you before things get really bad with tinnitus.
The question âcan headphones make you deaf?â 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.
World Radio Day on 13 February brings attention to the role of radio in managing disasters and recovery in their aftermath.
Radio is recognized as a low-cost medium, specifically suited to reach remote communities and is especially effective in reaching people affected by disasters when other means of communication are disrupted. Terrestrial radio broadcasts are effective in providing timely, relevant and practical information to people who are confused and demoralised by the impact of a crisis. Broadcast information is particularly useful in situations where physical access is difficult and aid responders may take several days or weeks to reach affected communities.
Recent natural and man-made disasters are a major cause for concern to the global community. âIn times of crisis and emergency, radio can be a lifeline,â said United Nations Secretary-General Ban Ki-moon. âFor people in shattered societies, or caught in catastrophe, or desperately seeking news, radio brings lifesaving information. This year, as we start carrying out the Sustainable Development Goals, let us resolve to use radio for human progress. On this World Radio Day, let us resolve to prove that radio saves lives.â
âRadiocommunication is indispensable in saving lives in the event of a natural disaster,â said ITU Secretary-General Houlin Zhao. âCollaborating and sharing experiences is critical in order to support national and regional preparedness, and ITU is deeply committed to facilitating rapid and effective response in emergencies.â
âAmidst the ruins and in the face of an emergency, the radio is often the first medium for survival,â says Irina Bokova, Director-General of UNESCO. âIts durability is an incomparable advantage, often enabling it to resist shocks and re-transmit messages of protection and prevention to as many people as possible, better and faster than other media, saving lives.â
New developments in radio technology and in the transmission and delivery of radio content, especially through mobile devices and through on-demand media platforms, further extend the means to engage disaster-affected communities. These digital innovations are increasingly important in delivering effective disaster preparedness and prevention, while reinforcing the importance of community radio services.
ITU has developed a number of standards for effective emergency radiocommunications, recognizing that direct communication via radio helps reduce the sense of isolation and helplessness experienced by crisis-affected communities. Recommendation ITU-R BT.1774-2 is the standard that relates to emergency warning systems for analogue broadcasting, which facilitates the use of satellite and terrestrial broadcast infrastructures for public warning, disaster mitigation and relief.
In addition, the 2015 ITU World Radiocommunication Conference (WRC-15) identified spectrum to facilitate mobile broadband communications for robust and reliable mission-critical emergency services in public protection and disaster relief (PPDR), such as police, fire, ambulances and disaster response teams. WRC-15 also reinforced protection to search and rescue beacons to uplink to satellites, such as the Cospas-Sarsat system, which has assisted in rescuing over 37,000 people worldwide since December 2013.
World Radio Day marks the anniversary of the first broadcast by UN Radio in 1946, when it transmitted its first call sign: âThis is the United Nations calling the peoples of the world.â Ever since, UN Radio broadcasts have highlighted the principles of the United Nations to foster world peace and development. World Radio Day seeks to raise awareness about the importance of radio, facilitate access to information through radio, and enhance networking among broadcasters.
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 thatâs 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 personâs 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.
