You may get confused about various types of walkie talkies on sale in the UK, or not be certain what type of walkie talkies you require , and what youâre legally allowed to use in some other countries that you plan to visit, or in your part of the world. Firstly, it is important to have in mind that any type of walkie talkie will function in any part of the world.
A walkie talkie is used on a channel that has a frequency associated with the walkie talkie. In other words, if a channel has a frequency different from that of a walkie talkie, then the two will not work together.
License Free Walkie Talkies
There are 446 license-free frequencies that can be used for leisure radios such as, Motorola talkabout, Binatone and Cobra radios. However, there are eight PMR466 frequencies or PMR466 channels that can be used.
The spacing between each of these frequencies is 12.5 kHz. As the system name suggests, PMR446 frequencies are located around 446MHz and are in the UHF segment of the radio range.
Even though they are not necessarily authorized, PMR446 frequencies are harmonized for use across European countries.
High level use of PMR446 frequencies may result in some annoying problems. However, these can be reduced or rectified by changing the frequency of the PMR446. Other systems such as DCS codes and CTCSS tone can as well help in alleviating the problems.
In view of the possible high use of the frequencies and the PMR446âs unlicensed nature, the scheme is not appropriate for individuals who need to gain access to frequencies at specific times and locations or for life use.
These are simple, short-range walkie talkies that conform to the European Union-wide PMR446 standard and can be used by any person in the United Kingdom or European Union without a license. These types of radios are commonly sold in High-Street shops as well as in most radio outlets.
Commonly known as “PMR446sâ radios that meet these standards usually have a power output of 0.5watts, meaning that their range is lower compared to the powerful business walkie talkies that are a licensed and which feature power outputs of 4-5 watts. All of them make use of the same eight channels and this causes problems sometimes if a given area has a lot of radio users using these channels.
Licensed Walkie Talkies
Two Way Radio for Business
Licensed handheld walkie talkies can have a power output of 5 watts, but “license free” PMR446 walkie talkies can only have 0.5watt power output. Therefore, the licensed walkie talkies usually have a better signal penetration and better range in buildings.
A majority of businesses prefer using a licensed 2-way walkie talkie system because, in spite of the benefits of license free walkie talkies (PMR 446), they have some downsides (like lower power, a short range and interference) which make them less effective than licensed business radio systems.
Taxi as well as other transport companies, and large sites like factories or hospitals, and businesses situated in a number of different locations are excellent examples of circumstances where a licensed radio system may be a favored option.
These situations require more powerful radios as opposed to hand-held portable walkie talkies with low frequencies. If the system of your radio relies on vehicle-mounted radios or a base station, a licensed radio system is necessary.
If you want start using a radio system in your business, then you will have to get a license from Ofcom. In other words, Ofcom is a company that controls who can transmit on what frequency and where, to ensure that different users donât interfere with each other.
Business radio system users range from factories and taxi companies, to industrial sites, hospitals, transport operators and care homes. To begin Ofcomâs licensing process there are a number of requirements that a business must first of all fulfil.
Ofcom license is especially important regarding official radio users like police, military, railways, air traffic control and emergency services, railways, etc. Radio systems that meet specific standards can be used without any license from Ofcom. For many walkie talkie users, license free radios will be okay. And if you are in need of a license, it isnât that expensive or complicated to get one.
The UK simple license is a license issued by Ofcom and gives holders the right to use more powerful radios. It is effectively a license to use powerful radios any place in the UK, using give frequencies which are shared by anyone using this license. This license is easy and quick to apply for, costs about Â£75 per organization, and is valid for 5 years.
It is the only option for people who need to use their radio systems anywhere in the United Kingdom, and is ideal for most business radios users.
This license provides you with specific frequencies or frequency allocated just for your organizationâs use within a given geographical area. The cost of the license varies from moderately cheap in most locations in the UK (about Â£100 annually), with the cost heightening in key cities, more so London, where the demand for radio frequencies is very high, going for up to more than Â£500 per year.
Radios that are designed to use dedicated frequencies such as this, should not be used outside of the licensed area, since the same frequency will possibly have been assigned to somebody else and you will therefore be causing interference to them.
UK Business Radio Suppliers License
This is a license for hire companies and radio equipment suppliers. It allows these companies to do short term radio hire via a set of frequencies allotted to radio hire companies. It also allows these companies to provide âdemoâ radio systems to potential customers and to undertake repairs to radio systems.
When these companies hire out their radio equipment, itâs hired using this license, so that the person hiring it does need to worry about licensing issues.
The importance of walkie talkies and radios in the UK and other parts of the world cannot be overlooked. Not only are these gadgets important in everyday communication, but they continue to play a very crucial role in the development of other communication tools. A lot of useful information about radios and walkie talkies has been highlighted in this article for the benefit of radio users and the public in general.
We have all watched star trek orÂ ‘Allo ‘Allo!Â (bare with us) and wondered how we can understand all the different languages. Well it is all down to the tardis! It translatesÂ the persons speech from their mouth to your ear so you can understand in perfectÂ English.Â But nowÂ you don’t need to keep a Tardis about with you, as they have designed a earpiece that can translate different languages, just pop it into your ear and talk to some foreigners. You can find the original article here.
How many times did you give up on befriending a foreign national due to language problem? Even if you have befriended the person who doesn’t speak your language, it becomes difficult to converse with him or her. You always feel Â the need to have a translator, whether it is a face-to-face conversation or a telephonic interaction.
Technology has the solution for any or every kind of problem in this world. It is advancing day-by-day so language barrier can no longer make you behave like an alien. Communicating with a foreign national in real time is no longer a pain as a company has come up with the Pilot earphones that let two people who speak different languages communicate smoothly with each other.
So there won’t be any awkward pause the next time you speak with your friend who doesn’t know your language. Also, there is no need to consult either a dictionary or search online the next time you want to talk to your French or Spanish friend.
In fact, Wavery Labs, a New York-based company that launched the wireless earphones, will add more languages as soon as possible. Currently the earphone translates only three languages – English, French and Spanish. The company will soon add Italian to its list.
You must be wondering about its functions. It works when you connect the earphones to two different people, speaking different languages and translates what they say in the ear.
Waverly Labs calls it the first ‘smart earpiece’. But it hasn’t disclosed much detail about how it works. According to the company, the earphone uses “translation technology” embedded in an app. The Pilot will cost $129 (around Rs. 8,646) and will be available for pre-order on their website.
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 doâ¦..
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 theÂ 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.
“After analyzing the situation, Astrid requested all user organizations to sit around theÂ 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.
Have you ever stopped to think where headsets really came from? Well, they first headset was used in the 20th century; however, the technology has significantly improved over the decades. Shockingly it did not occur to anyone that headsets could be used to listening music on devices. Read more about the invention of radio headset in this article.
Headsets are an important accessory and it is very clear that they have indeed managed to save an argument over the years. Headsets enable you to listen to audio/music without having to get in the way of anyone else. In this time and age, we use all types of headsets from tiny earplugs with a wireless Bluetooth technology for listening to music in the streets, to big leather-padded cans to listen to music at home. Gaming headsets are increasingly becoming popular as many of them today come outfitted with a microphone, hence allowing the users to speak with other relatives, gamers and friends.
Headsets can give the user a great sound quality, there isnât any sort of interruption between the ear and the sound, external sound is blocked out and there is absolutely nowhere for it to dissipate, more so if you invest in a pair of high quality headsets which are plentifully available nowadays. As a matter of fact, if you take a walk back to the early 20th century right before amplifiers had been invented; sensitive headsets were the only means that was could be used to listen to music/audio.
Accurately speaking, the very first headset dates back to the telephone early adoption and by 1920 radio headsets were being commercially manufactured. These were mainly used by professionals and not by the public. There exists an argument over who was first person behind the idea to dwindle down loudspeakers and move on to attach them on our heads but the earliest living example dates back to around 1911. This was far from the headsets we use presently with no padding for comfort and a very low sound quality. They were used by telephone exchanges and radio operators.
Headsets were the only way to listen to audio files before the development of amplifiers. Headsets were invented in 1910 by Nathaniel Baldwin, an American born to a Canadian father and an American mother. Baldwin developed the first, truly successful set in 1910 by hand in his kitchen and later sold them to US Navy.
Baldwinâs headsets made use of moving iron drivers that came with either balanced or single ended armatures. The requirement for high-sensitivity meant damping could not be used, and hence they had a crude sound quality. These early models did not have padding, and oftentimes ended up producing excessive clamping force on the heads of persons wearing them.
In 1944, John C. Koss a jazz musician and an audiophile from Milwaukee, US, designed the first stereo headset. Previously, headsets were used only by radio and telephone operators, as well as persons in related industries. The 3.5-mm phone connector and radio headset, which is commonly used in portable applications today, has been in use since the Sony EFM117J radio that was released in 1965.
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 isnât 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 âmusicâ and âearplugsâ 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 highÂ riskÂ of bias, in the reviewersâ 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 couldnât combine their dataÂ 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.
âFrankly, with such a small comparator group between three subjects and the others, it would be hard to assess validity of plugs or not,â said Dr. Jennifer Derebery, president of the Los Angeles Society of Otolaryngology and lead author of the first study.
âWe had trained them all in proper insertion, and encouraged but not required wearing them,â 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.
âEar plugs are effective in preventing hearing loss when they are used both correctly and consistently,â 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.
âThis systematic review highlights the very limited data on prevention of recreational music-induced hearing loss using earplugs,â Le Prell told Reuters Health by email.
âAt 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,â Le Prell said. âA significant number of youth are also involved in target shooting activities, which children can get involved with through Boy Scouts or other organizations.â
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.
âMost concerts are both loud enough, and long enough, that they are likely to exceed the total daily exposure allowed by workplace safety regulations,â she said. âSound 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.â
For workplace noise exposure, âwe are not doing a very good job achieving correct and consistent use of hearing protection devices (HPD), including both ear plugs and ear muffs,â she said.
âIn the United States, it is relatively uncommon for music venues to provide ear plugs at no charge,â 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.
âAs a neurotologist, it really is upsetting to see these kids coming in younger and younger with a completely preventable hearing loss,â Derebery said.
The first two way radio made its way into the Western market in 1923. Despite its late appearance, the device was primarily conceptualized in 1907 as part of a military communication program. There has been some controversy regarding who first made the two way radio. However, most people seem to attribute this invention to Frederick William Downie, Senior Constable of the Victorian Police in Australia. In this article, we take a look at the path that this radio has traversed through the ages- from 1907 to the 21st century.
Origin of the 2 Way Radio
In the 1900s of Australia, the 2 way radio was installed in police cars and used as means of communication for the purposes of surveillance, checking locations and keeping team mates posted on updates. This was a breakthrough invention for the police as it caused an instant increase in the overall efficiency of working. From instant reports to integrated surveillance systems, the two way radio was pivotal in improving the effectiveness of the Australian police force. Suddenly, people discovered the ease with which the law of the land could be enforced and security could be maintained. This was the one method by means whereof many lives were saved and the state became one of the safest places in the world. Needless to say, the overwhelming response that the two way radio received propelled it to fame and it then became one of the most popular methods of law enforcement in the world.
The popularity of the 2 way radio rose steadily over the years. From police cars, the deviceâs many uses branched out and it became a part of navy ships and even military operations. Since many mariners and platoon commanders faced problems of communication, the convenience of the two-way radio was highly appealing to all. Transmissions of messages became convenient and there was a certain smoothness that the radio communication afforded to the operations.
The Creation of the Modern Day 2- Way Radio
The global status that the 2 way radio enjoyed is also one of the biggest reasons for its adaptation into various communicative derivatives including the modern day walkie talkie and even the modern cellular phone. Before it achieved this global, improved status; however; the two way radio was one of the most rudimentary objects that could be used in police surveillance. The first radio was so heavy and cumbersome that it used to take up the entire backseat of the police car. While it might have had many benefits, the sheer size and volume of the object made it difficult to catch and apprehend criminals at the earliest. With technological improvements and the right incentive, the two way radio has improved leaps and bounds. What once used to occupy almost half the car space can now be fitted into a pocket with ease, while fulfilling the same purpose as its predecessor.
Uses and Benefits of the Modern Radio
From the 1900s to the 21st century, the two way radio has made immense progress. What earlier was used exclusively by the police had now become an instrument in the civilian space. From law enforcers to children, almost everyone could purchase walkie talkies and use it. This was the first time that the world saw the walkie talkie as an instrument of recreation. These days, walkie talkies are used as much by kids for their games as they are used by professionals in emergency situations. From medical EMTs to firefighters, walkie talkies have become a regular in the cityâs working scenario.
One of the biggest uses of walkie talkies these days are in firefighting operations. Coordinating external help and amassing the required support for the rescue operation are common functions that are carried out over the two way radio system that was once pioneered by Downie. Over and above its use in emergency situation, the two way radio is also used for the basic purposes of communication and organization in construction sites, among municipal workers and in many facets of working companies.
When one considers the many benefits that the 2 way radio has brought to the world population, one cannot help but pay homage to the genius of Frederick Downie. While the remarkable transformation through the ages is something that we must all bear in mind, it is undeniable that the blueprint was an instance of pure creative and imaginative genius. There are multiple uses of the walkie talkie in the modern world today. From communication in emergency situations to its importance for recreation, the modern two way radio is arguably one of the most important facets of communicative technology. All in all, the genesis and development of the two way radio is undoubtedly one of the most outstanding creations of the previous century.
This article was originally posted on thestage.co.uk and they highlight that the use of earpieces for prompting actors is increasing, this very simple technology used in this way makes people uncomfortable. But why? Earpieces these days are so small that people standing really close to the wearer would have literally be standing on top of them to see it, let alone be 15m away. Maybe itâs the thought that the actor should be able to remember their lines? or that bringing undue technology into the theatre would decrease the value of it?
Car crash theatre. That’s how a colleague described Al Pacino’s return to the Broadway stage in David Mamet’s new play,Â China Doll.
For those who may not have been following the story,Â Pacino’s return to Broadway has been blighted with problems âÂ most notably, reports that he cannot remember his lines. Teleprompters have been installed around the stage and Pacino wears an earpiece,Â even after the production’s opening was delayed.
Pacino is not the only star on Broadway this season getting help with his lines. If reports are to be believed,Â Bruce Willis inÂ MiseryÂ is also being given a helpful prompt or two through an earpiece,Â as are Cicely Tyson and James Earl Jones inÂ The Gin Game.
However,Â Pacino seems to be the main focus of press criticism and a large part of me feels sorry for him. Undoubtedly, he is under intense pressure âÂ despite past success on Broadway, he is in danger of being remembered best, if not most fondly, for China Doll.
The sign outside the Schoenfeld Theater quotes a line from Pacinoâs character in the play: âCan you just tell me whatâs happening?â In the circumstances, it seems both ironic and ill-judged. Meanwhile, around the corner at the St James Theatre, the comedy musical Something Rotten has put up a cheeky, if somewhat venomous, sign on its canopy, saying: âAll actors promise to memorize most of their linesâ.
For any actor,Â it is terrifying to think that one day, no longer being able to remember your lines, you may not be able to work.Â TheÂ interesting point about this situation is that the media have been far more forgiving ofÂ other actors: Tyson and Jones have been treated as beloved national treasures. At 90 and 84 years old respectively,Â they have a few years on 75-year-old Pacino and therefore it’s may be understandable that they require prompts. A similar response greeted Angela Lansbury who,Â inÂ Blithe SpiritÂ on Broadway and in the West End,Â wore a cleverly designed hat which incorporated ear pieces.
Despite criticism of Pacino’s use of prompting devices,Â China Doll has not seen a slump at the box office. AudiencesÂ seem to be happy to pay top-dollar ticket prices to see their favourite stars on stage whether they know their lines or not. Does this mean we accept that teleprompters and earpieces will become inevitable in theatres? Has a precedent now been set for Hollywood actors to slip into a play during a gap in their moviemaking schedules believing they donât need to spend time learning lines? Will audiencesÂ continue to tolerateÂ this because of that starâs status and the opportunity to see them live?
I hope not: knowing lines is a fundamental skill in the craft of acting. I want to see star actors on stage but I also want to see and remember them at their best. And the reporting of apparent production problems does nothing to help a theatre industry already faced with an audience which may expect or hope for a disaster on stage to tweet about; the resulting social media noise overshadows anything else to do with the play itself.
China Doll is â on paper â a hit show, with its headline star bringing in high weekly grosses that will likely see the play recoup. But in the long term that should not be the only way to judge the success of a production.Teleprompters and earpieces are changing theatre, and not necessarily for the better
One question that is frequently asked by people interested in buying two way radios is that can you mix brands of two way radios. To answer this question properly, it is imperative to understand first how the devices work. It should be known that whether you have a small business or a large warehousing facility, UHF band radios never communicate with the VHF band radios. Therefore, if you are looking to buy a radio, make sure to buy additional units of the device of similar bands. In this way be it a UHF band radio or a VHF band radio, if set to the same frequency can work with all brands. However, some considerations have to be put in its place beforehand.
Two way radios imply that it can both send as well as receive radio messages. They are transceivers that are battery powered. The radios operate on a half-duplex channel system. This system implies that the radio will be able to transmit a signal on a single channel that can be received on many devices at the same time. Normally these radios are designed to transmit short-range signals. Almost all of the two way radios function on the same principle. They all include a microphone, an antenna, a speaker, and the Push to talk Button. These radios are designed to function on different frequencies.
The general public use frequencies are the Family radio service frequency or the FRS and the general Mobile radio Service frequency or GMRS. Both these frequencies work on a 460 MHz rage. The UHF frequency or the ultra-high frequency is ideal for the two way radios as they can easily penetrate the interference in the form of building and trees. The two way radio with a long UHF antenna will push through the concrete and will do your work efficiently. On the other hand, VHF antennas on the radios are much longer than the ones in the UHF radios. These are ideal to use in the outdoors as they usually can transmit signals over very large distances.
Types of radios
There are normally two types of radios, that are used in businesses and that are used in consumer situations. The consumer radios normally work on the FRS or the GMRS frequencies. Regardless of the number of channels in the radio, the two way radios can be mixed with other brand radios . Only the radios have to be set to the same privacy code, the channel number, and the same frequency. Alternatively, there are several different types of frequency in the business two way radios category. The radios use the UHF, VHF and the 800/900 MHz type frequency. Just by choosing, the radio with the same frequency may not be compatible with the radios of other brands bought beforehand. While buying the radio, the dealer may have programmed a special customized frequency into the radio beforehand. In order for the business, two way radios to work efficiently with the radios of different brands it is essential to completely figure the type of band that the radio uses, the pre-set frequency on the radio from the dealer.
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.
Established in 1976, ETRI is a non-profit Korean government-funded research organization that has been at the forefront of technological excellence for about 40 years. In the 1980s, ETRI developed TDX (Time Division Exchange) and 4M DRAM. In the 1990s, ETRI commercialized CDMA (Code Division Multiple Access) for the first time in the world. In the 2000s, ETRI developed Terrestrial DMB, WiBro, and LTE-A, which became the foundation of mobile communications.
Recently, as a global ICT leader, ETRI has been advancing communication and convergence by developing Ship Area Network technology, Genie Talk (world class portable automatic interpretation; Korean-English/Japanese/Chinese), and automated valet parking technology. As of 2015, ETRI has about 2,000 employees where about 1,800 of them are researchers.
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.
As this article shows,Â Motorola move closer to sealing the deal to supply the emergency services for the whole of theÂ UK, this move seems to proveÂ what we have been saying, as Airwave have a workingÂ relationshipÂ with the emergency services and a good majority of the equipment they use are Motorolas’ own products they are in an excellent position now.
Walkie-talkie and radio systems maker Motorola Solutions Inc said it would buy UK-based communications company Airwave Solutions Ltd for 817.5 million pounds ($1.24 billion) to beef up its services business.
Shares of Schaumburg, Illinois-based Motorola were up 3.4 percent in extended trading on Thursday.
Airwave, owned by a fund of Australia’s Macquarie Group Ltd, provides voice and dataÂ communicationsÂ to more than 300 emergency and public service agencies in Great Britain.
Motorola’s sales have slipped as its major customers, which include police and fire departments as well as other government agencies, curtail budgets.
The company is trying to strengthen its services businessÂ – which provides communication services to governments, businesses and public safety agencies – to drive growth.
Activist investor ValueAct, Motorola’s largest shareholder, said last month the company’s shares were undervalued and that it would talk to its board about ways to enhance shareholder value.
Motorola Solutions said it plans to fund the purchase of Airwave, which has about 600 employees, with bank financing and cash on hand.
The deal is expected to add to adjusted earnings and free cash flow immediately after closing in the first quarter of 2016, Motorola said.
The 4-day 62nd Macau Grand Prix was rounded off at Macau Guia Circuit on November 22nd with over 80,000 audiences entering into the circuit to experience the fast and furious brought by the world top drivers and cars. Since tentative collaboration with the event committee in 2013 and 2014, Hytera was finally chosen as the official radio supplier this year to replace the legacy system and terminals with up-to-date communication equipments which helps the event committee organize and manage the global renowned sporting event in Macau.
The Macau Grand Prix is a historical street racing and known as one of the most demanding circuits in the world due to the challenging nature of the track, which consists of fast straights, tight corners and uncompromising crash barriers. Accidents happen almost in every racing competition. This year is not an exception.
Considering the potential circumstances would happen during the race, a tailor-made DMR two-way radio solution to fulfill multiple synchronized calls were proposed by Hytera and adopted by the event committee and all the supporting staff scattered along the circuit. “I have to praise all the supporting staff this year, they have done a very good job in handling the emergencies on the track with really high efficiency,” the live broadcast presenter commented. The radio communication between committee and the execution teams has made indispensable contribution for the high efficiency.
“The adoption by Macau Grand Prix is a significant breakthrough and a great recognition for Hytera,” said Sam Cheung, the Sales Engineer of Unicom Technology, regional partner of Hytera in Hong Kong and Macau.
In addition to the massive use on the track, the Hytera radios can be also found in the pit lane by several racing teams which includes the one FIA F3 defending champion Felix Rosenqvist drives. The Swedish driver successfully retained his championship title in the Suncity Group Formula 3 Macau Grand Prix – FIA F3 Intercontinental Cup this year. “The Hytera PD788 portable radios used by the racing teams are not part of the agreement but brought by the teams themselves,” said Kuan Weng Fai, the owner of Shun Tat Electronic Engineering, local partner of Hytera in Macau.
Besides the official collaboration with Grand Prix Macau, Hytera also facilitated Macau International Marathon for the first time; in addition, Hytera completed projects for Top 3 bus services operators in Macau including Transportes Urbanos de Macau, Sociedade de Transportes Colectivos de Macau and Macau Nova Era De Autocarros Publicos, which marks big breakthrough in the field of mass transit segment; in the meantime, Hytera also fulfilled a number of commercial projects such as FBC Centre, Macau Golf Country Club, Suncity Group and Galaxy Macau Phase II and Broadway Macau, a new landmark destination launched in May this year for Macau. “It is our honor to have the recognition from customers, we will carry on our work to satisfy more and more customers in Macau,” said Wilson Hu, Sales Director of Hytera.
The Macau Grand Prix is a motor racing event, surprisingly held in Macau, China. So itâs not a surprise that the biggest two way radio communication company, based in china, are suppliers of the communications. Itâs known as a street circuit race for cars and bikes, the only one in the world. Held in November with one of the highlights a Formula 3 race with the winner being awarded theÂ FIA Formula 3 Intercontinental Cup. We sourced this article from hereÂ
This very simple,Â very easily executable solution to a problem that is growing. The Frequencies are already allocated to the airline industry and a simple piece of equipment (non expensive) can be installed. You can find the full article here.
The International Telecommunication Union (ITU) has allocated radio spectrum for global flight tracking for passenger aircraft using satellite-based systems.
The move follows developments spurred by the so far unexplained disappearance of Malaysia Airlines Flight 370 in March last year, which prompted the aviation community to look into possibilities of constant monitoring of passenger planes in flight.
TheÂ frequency band of 1087.7-1092.3MHz has been allocated, which is already being used for data transmissions between planes and terrestrial stations that are within the line of sight.
Extending the system to cover also communications between planes and satellites and satellites and terrestrial stations will enable creating a complex system capable of tracking passenger planes throughout the flight even over oceans and remote areas.
The ITU agreed on the allocation at its 2015 World Radiocommunication Conference following a call by the International Civil Aviation Organisation (ICAO).
Performance criteria for satellite reception of the signals will be established by ICAO.
âIn reaching this agreement at WRC-15, ITU has responded in record time to the expectations of the global community on the major issue concerning global flight tracking,â said ITU Secretary-General Houlin Zhao. âITU will continue to make every effort to improve flight tracking for civil aviation.â
ITU has been working on standards to facilitate the transmission of flight data in real time since early after the MH370 disaster.
Already in April 2014, less than a month after the aircraftâs disappearance, Malaysian Minister for Communications and Multimedia called upon ITU to address the issue.
âThe allocation of frequencies for reception of ADS-B signals from aircraft by space stations will enable real-time tracking of aircraft anywhere in the world,â said FranÃ§ois Rancy, Director of the ITU Radiocommunication Bureau. âWe will continue to work with ICAO and other international organizations to enhance safety in the skies.â
In October 2014, the ITU Plenipotentiary Conference meeting in Busan, Republic of Korea, instructed WRC-15 to consider global flight tracking in its agenda.
Cancer affects millions of lives, possibly even more. Everybody knows somebody that has been forever hurt, either physically or emotionally, by this vicious, unforgiving ailment. Most of us know somebody who has lost their life to the disease.
Despite this, cancer survival rates are higher than ever before. In recent years, cancer treatment has improved rapidly, but a complete cure has always appeared to be just beyond reach, a tantalising Holy Grail of medical science. This month, however, an announcement was made that could have the potential to end all that.
The good news is that human trials could begin in as little as four yearsâ time. If those trials prove to be successful, then science will have made a major stride towards eradicating the disease completely.
A joint Dutch/Canadian team stumbled across this miraculous discovery whilst searching for ways to treat malaria in pregnant women.
According to the team, the carbohydrate that malaria attacks in the placenta is exactly the same as a carbohydrate present in cancer cells.
As Metro.co.uk reports, Ali Salanti from the University of Copenhagen said, âfor decades, scientists have been searching for similarities between the growth of a placenta and a tumor (…) The placenta is an organ, which within a few months grows from only few cells into an organ weighing approx. two pounds, and it provides the embryo with oxygen and nourishment in a relatively foreign environment. (…) In a manner of speaking, tumors do much the same, they grow aggressively in a relatively foreign environment.â
Intrigued by this idea, the team tailored a special malaria protein to include a toxin designed to target cancerous cells. The cancer cells absorb the protein and are then in turn killed by the malaria virus. Theoretically, this idea is sound and experiments on mice with cancer have already begun.
Itâs definitely early days yet, but the team are hopeful that this innovative new treatment could provide scientists with a valuable weapon in the fight against cancer. If the trials are successful, the potential benefits are simply staggering to consider. It just goes to show that no dream is too big to accomplish, provided we never stop believing that itâs possible. Imagine a world without cancer and perhaps, in time, we wonât have to.
