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.

Cover your ears! Amsterdam Dance Event goers invited to hearing pill tests

Anyone will tell you, we are the first to champion hearing protection and the progress to hearing health. With all the latest technological developments, we are looking at a new era of hearing health. This supplement is supposed to ‘be beneficial for reducing hearing loss due to aminoglycosides and overstimulation’ and if the test come back positive we might see further advancement in this field.

The Amsterdam Dance Event is about more than top DJs and partying, reports Senay Boztas

As 375,000 people prepare themselves for big noise at the five-day Amsterdam Dance Event, a business has asked them to listen up: Hearing Health Science is looking for recruits to trial its ‘protective’ hearing pills.

The Amsterdam-based business, co-founded by a leading inner ear neuroscientist from the University of Michigan Dr Josef Miller, has joint US patents on a dietary supplement combination including vitamins A, C, E and magnesium.

Studies have shown some evidence that this ACEMg supplement ‘can be beneficial for reducing hearing loss due to aminoglycosides and overstimulation,’ according to a report in Nature magazine in February, co-authored by Miller. Hearing Health Science hopes to begin producing pills next year and is taking pre-orders at the festival, at a cost of €30 for a four-week supply.

Pilots

It is also looking for volunteers to take part in pilot tests, signing up recruits at the Amsterdam Dance Event, which this year is putting on 2,200 acts in 140 venues and expecting a peak of numbers.

Barry Seifer, co-founder and chief executive of the company explained: ‘The pill we are bringing to market is safe, and you cannot test in the lab by giving someone a problem and then offering to cure it. If you are going to do epidemiological research on something like this – noise – you have to do it in the real world, where the problem happens. This is a great place to do that research.’

The company is planning pilot tests with volunteers from the ADE – although Seifer said they won’t be handing out pills at the door – and hopes to invite some of these to a modified crossover study. This should take place when the ‘festival’ season begins from March next year, and subjects will be followed for a period, taking the drug and a placebo at different times, and measuring their hearing through a special app developed at the University of Michigan.

Tinnitus

‘We’ve done it once with a tinnitus trial and now we want to do real-world studies in the music industry,’ says Seifer. ‘Our initial idea was to recruit 20 or 30 people but we have such intense interest that I think we’ll have 500 who sign up. We would love to be able to give this to people now because millions need help, but we’re not quite there yet. We’re not going to stand at the doors and hand out pills.’

A spokesman for ADE said the festival has worked with Hearing Health Science in the past and invited it to speak at an event on Thursday. ‘We believe you need to protect your hearing and welcome initiatives in this field,’ he said. ‘HHS has been working on this hearing protection for a long time and at ADE we are always looking out for innovations in the field of (electronic) music…we also actively offer earbuds to visitors.’

Highlights of the event this year include Afrojack, Hardwell and Martin Garrix, and the festival expects 3% more clubbers, with a steadily pattern of growth over its 10 years. House music and techno are currently the most popular genres.

Seifer adds: ‘We would never tell you to turn the music down. Entertainment goers are trying to keep the music to lower volumes and encourage people to use filters and party plugs – these are good. The problem is that this is supposed to be fun!’

Is there a Best 2 way Radio For Long Range

When choosing the best two way radio , it is important to note that doesn’t matter which brand you pick. Whether you pick kenwood, Motorola, Icom, Hytera or any other brand, you should know that they all feature the same technology. Well, you might have noticed that most consumer radios tend to advertise a range that’s up to 30 miles. Truth is, the consumer FRS/GMRS radios don’t even provide anything close to the advertised maximum range; the range that a 2 way radio advertises is normally the range that a radio can get in the ideal condition. The ideal condition is clear line of sight like from the mountain top to the valley below; without any interference or obstructions.

Two way radios generally operate within VHF (that is Very High Frequency; 130 to 174MHzz) and UHF (that is, Ultra High Frequency; 420 – 470 MHz)) wave bands. Unlike the frequencies that are below 2MHz, the waves in these particularly higher frequencies travel in a straight line (also known as line of sight signal), and generally can’t travel beyond your horizon. This basically means that distance to your horizon, is the actual maximum range for your 2 way radio; that is without the use of any additional equipment to boost the signals.

VHF waves (about 5 feet wide), are generally longer than the UHF waves, and they’re most commonly used for long range/distance communication. If VHF waves and UHF waves were both transmitted in ideal conditions without any barriers, the VHF waves would travel nearly twice as far; as a general rule, the lower the wave frequency, the greater the distances it can travel.

Key to transmitting the radio waves for a long distance along the VHF waves is keeping the receiver and the transmitting radio above all possible obstructions or interfering objects. The VHF frequencies (because of the length of their waves), cannot transmit through some objects like walls, dense forests and hills. Typically, the transmissions which are sent along VHF waves are received and also sent high above earth’s surface. VHF 2 way radios normally work better when there is a clear line of sight between the receiver and the sender. VHF 2 way radios are commonly used in marine and aviation communications where signals get sent across the open water bodies or between the ground and the sky. Television and FM radios also use the VHF frequencies where the signals are sent and also received high at the top of towers which are spaced all over the towns, cities and counties. VHF band walkie talkies are also perfect for landscaping, open fields, golf courses and also for outdoors security situations where there is less obstruction.

Though VHF can travel much farther, it doesn’t mean it is the better option. Reason is because of the differences between how the VHF and the UHF signals tend to react around buildings or structures. As you will find out below, UHF signals are shorter than VHF, and this is very important when you’re in or around buildings.

UHF doesn’t travel as far as the VHF, but has higher bandwidth occupation. One major advantage of UHF over the VHF, is that the antenna can actually be much smaller when its’ used on the higher frequencies. Sometimes, a base antenna might be needed for radios using VHF frequency, but a small antenna on a radio can be comfortably used for the UHF frequency. Moreover, there are a lot more frequencies which are available when using UHF; this can be very useful in the areas which have a high population density.

The UHF radio waves are much shorter than the VHF radio waves (measuring at about one and half feet); the short length of UHF radio waves typically decreases distances at which the signals can get transmitted. This means that the line of sight between the receiver and the sender is much shorter in length with UHF waves. That being so, you should know that transmission of the UHF waves is usually high enough such that it can penetrate through the building walls and the urban outdoor settings. This is the reason why UHF two way radios usually work best for those who intend to use them in and around buildings and urban areas. A UHF walkie talkie with adequate power and a good sized antenna can reach further into the building, and push through steel, wood, concrete and earth. If you intend to use your 2 way radios exclusively indoors, or maybe indoors and at times outdoors, the the UHF is definitely the best choice. To explain this, let us use an example; assume you’re trying to communicate with someone on the other side of the building and in between there’s a metal wall which has a 3 foot opening. Basically, radio waves can’t pass through metal. However, the UHF wavelength which is about 1 1/2 ft wide, will easily pass through the opening. In contrast, the VHF signal will bounce back since it’s wider than the opening. This shows you that UHF is much better when it comes to navigating through smaller spaces within buildings to reach its’ destination.

When it comes to power, many people tend to think that the power output increases the range, but actually the difference in the range between, say a 25W fixed VHF, and a 5W handheld, is because the fixed mounts the antenna being taller, thus can see farther. When you are trying to increase the range, increasing the height of your antenna is far more effective than increasing the power. Increased power will generally let you push through the static and such other radio traffic much better, but only within a range that’s dictated by the height of the antenna.

In regards to obstacles, there are a lot of things which affect the signal strength of the radio waves. Therefore, it’s important to consider the environment you intend to use your 2 way radios, and the actual range you need. Naturally, a football stadium will have much less obstructions as compared to a dense forest.

In conclusion, I would like to say that it is never about the radio you purchase, but the frequency, antenna and environment it will be used in. If your 2 way radio is going to be used mainly outdoors, where you will have a clear line of sight, then the VHF is the ideal choice, however, if the two way radio is going to be used in and around buildings, in urban areas, or in heavily wooded places, then the UHF is the best option.

Music From Your Sunglasses? Zungle’s Founders Crowdfund $2M For Shades With Bone-Conduction Speakers

Anything with bone conducting technology, we will jump upon and love the hell out of! When we heard about Sunglasses that had speakers with bone conducting inside, to allow you to make calls and listen to music whilst on the move we thought what a great idea. This crowd-funder is looking to raise $50,000 but $1 million would be a good start. See more on this here.

One of the latest hot crowdfunding campaigns is for dark sunglasses called the Zungle Panther with bone-conduction technology that allows them to be used to listen to music and make phone calls. Jason Yang, Zungle’s 30-year-old CEO and co-founder, came up with the idea because he was annoyed with trying to wear an earpiece and sunglasses to listen to music while wakeboarding.

“We all love extreme sports, and Jason is a huge fan of wakeboarding,” says Sean Bang, 30, Zungle’s chief marketing officer and co-founder. “He’ll have sunglasses on, but eventually the earphone doesn’t work with the sunglasses, and he felt that it was inconvenient and uncomfortable. So we decided to get rid of the inconvenience.”

With Zungle’s sunglasses, wearers can listen to music or make phone calls while skiing, biking or wakeboarding without worrying about an additional earpiece. Bone-conduction technology, in which you hear sound through vibrations to your skull rather than through your ears, isn’t new. But the idea of putting it into relatively inexpensive consumer products, like sunglasses, has been gaining traction recently.

So after fiddling with the product for nearly a year, in June, the two friends, who had worked together at marketing firm Innocean Worldwide in South Korea, along with two other cofounders, Chris Hong and Injun Park, turned to Kickstarter with a stated goal of $50,000 for their high-tech sunglasses. As with many crowdfunding campaigns, that $50,000 number was a lowball one; Yang says “about $1 million” was their actual goal. The Zungle Panther has a similar look to Oakley’s shades, and retails for $150. Backers who chipped in $89 could get them in a choice of colors as a “reward.” “When we started, we didn’t have enough money to create this product,” Bang says. “We chose Kickstarter because we can target everyone around the globe.”

By the time the campaign ended, in mid-July, Zungle had raised more than $1.9 million, putting it among Kickstarter’s top 100 campaigns of all-time.

What Walkie Talkie Channel Can I Use

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 you’re 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 PMR446’s 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 “PMR446s” 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.

Ofcom

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 don’t 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 Ofcom’s 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 isn’t 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 £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.

Geographic License

This license provides you with specific frequencies or frequency allocated just for your organization’s use within a given geographical area. The cost of the license varies from moderately cheap in most locations in the UK (about £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 £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 ‘demo’ radio systems to potential customers and to undertake repairs to radio systems.

When these companies hire out their radio equipment, it’s hired using this license, so that the person hiring it does need to worry about licensing issues.

Summary

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.

Sony Announces AI Assistant Earpiece to Go on Sale in November

Smart earpieces are the next frontier for the smart generation, we have all seen the earpiece that can translate instantly But that is just the start, as we can see from this article about this Xperia Ear wireless earpiece, it updates you from your phone when you put it in your ear. It won’t be long before we won’t need a smart phone everything will be in our ear.

Sony has revealed its ‘smart personal assistant’ that include a bluetooth earpiece will go on sale in November.

At the IFA show in Berlin today, the firm confirmed it will launch this November ‘starting in select markets,’ although its price has still not been revealed.

The Xperia Ear wireless earpiece can update you with any missed calls or messages as soon as you slot it into your ear.

The firm also showed off a Xperia Agent, a robot measuring just over one foot tall, that also works as a PA.

‘It will navigate you to where you want to go and make your life eye-free and hands-free,’ said Sony Mobile’s President and boss, Hiroki Totoki of the ‘her’ earpiece when it was unveiled at the MWC show earlier in the year.

‘It is also powered by Sony’s voice technology and will respond to a number of commands.’

The firm says the smart earpiece ‘is a next-generation wireless ear-piece that brings a new way of communicating, without compromising on enjoying the world around you.’

It reads users information such as your schedule, weather and the latest news to keep you up-to-date on the go.

Powered by Sony’s voice technology, it responds to verbal commands, so you can ask it to make a call, perform an internet search, dictate a message or navigate to a certain location.

It connects to an Android smartphone via NFC or Bluetooth and talks to a host application, where you can customise settings, including the info you need when you first connect in the morning, touch commands and app notifications.

‘Its lightweight and comfortable soft silicone ear-bud is built for continuous wear, with IPX2 water-protection and all-day battery life3,’ Sony said.

It’s available in Graphite Black and the innovative case doubles as a charger, so you can simply pop it in when you need to recharge.

It also unveiled the Xperia Eye, a wearable camera that acts as your personal sidekick, capturing everyday life moments with a 360 degree wide-angle lens.

Unveiled at Mobile World Congress (MWC) in Barcelona, the Xperia Eye can be attached to clothing or worn around the neck.

It forms part of a suite of connected gadgets designed to free people up from their phones.

Sony said the Xperia Eye is ‘a vision for a personalised assistant’ and joins three other smart gadgets that are connected to a Sony smartphone that acts as a hub, feeding information to them such as notifications.

These are Xperia Agent, Xperia Project and Xperia Ear.

Xperia Agent is a security camera-style device which acts as a home monitoring system, keeping an eye on what’s going on around it and projecting notifications fed to it from a Sony smartphone onto surfaces around it.

‘It will provide you with useful information, communication assistance and home appliance controls,’ Sony said.

Xperia Project projects an interactive interface onto any clear surface, meaning you can manipulate images, webpages and screens you would usually find on your smartphone, onto a hard surface.

Sony claims this projected image will respond to touch, voice and gestures just as someone would interact with your smartphone screen.

The Xperia Ear is a wireless earpiece that will update you with any missed calls or messages as soon as you slot it into your ear.

‘It will navigate you to where you want to go and make your life eye-free and hands-free,’ said Sony Mobile’s President and boss, Hiroki Totoki.

‘It is also powered by Sony’s voice technology and will respond to a number of commands.’

The wearable camera is the first time Sony has shrunk its image sensing and camera technology into such a small device.

Motorola Solutions CTO: Public Safety Will Be Transformed By Data-Driven Communications

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. 

Motorola Solutions CTO Paul Steinberg explains how data and enhanced communications can make cities safer – even if they’re not smart just yet

As CTO of Motorola Solutions (MSI), Paul Steinberg says he has three broad remits.

paul-steinberg-motorolaThe first is to advance the company’s technology with his team of engineers and data scientists, the second is to drive its patent strategy (“What patents we get and what we do with them”) and the third is to invest in startups so MSI can get access to something it doesn’t have.

“It keeps you humble because there’s always someone else doing things faster and better than you,” he tells TechWeekEurope.

Public safety

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 its handheld computing division to Zebra Technologies in 2014.

This might seem like a very narrow focus but it’s 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 with EE to help deliver the £1 billion Emergency Services Network (ESN) – a 4G platform that will allow for data-enabled services alongside critical communications – and save the government £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.

“[Mission critical communications are] every bit as important as they have been and we expect [them] to be tomorrow,” explains Steinberg.

“Mission critical intelligence brings in connecting things – data. It becomes more about context and situational awareness. The investments we’re making are more in that direction.

“One of the things we’ve been working on is the connected first responder. What we did was we built a context engine that’s at the heart.”EE 4G (3)

Context engine

The ‘context engine’ 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.

“Why did we do the Context engine? ‘Eyes open, hands free’: keep focussed on what you’re doing and keep your hands available to do what you need to do,” said Steinberg.

“We 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.”

Connected platform

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.

Motorola Solutions public safety (3)“[Takeovers] give us technology or a skillset that we can’t do properly [ourselves],” he explains. “If the concept looks like it has legs, that’s when we make the decision. In some cases we don’t proceed.”

Sometimes the target is more established. MSI has bought Airwave for £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.

“It brings us another data point but it doesn’t really change how my team works,” he says. “It’s a company that helps us ensure we have an orderly migration.”

Smart cities and smart vehicles

MSI says the Context Engine and its vision of data-supported communications will be strengthened by the parallel development of smart cities; even if it’s too early to have any impact right now. Steinberg describes ‘shotspotter’ technology capable of detecting when and where a gunshot is fired, aiding emergency services, and believes smart cars will also play a role.

“I think as the city becomes smarter, we can benefit from the environment,” he predicts. “We 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.”

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.

“The foundation of our business is communications and it always will be,” he states. “Making sure our platform is resilient, usable and mission critical in harsh environments while layering on this intelligence.”

Ericsson first to deliver 5G NR radio

We are seeing a new era in communications at the moment, the move from tetra and RF to the mobile network. The uk’s emergency services will be moved over to EE’s ESN system slowly until 2020 using Motorola kit designed particularly for the technology. The natural evolution is 5G, which we won’t see for many years, but Ericsson have taken the baton and are running with it.

  • World’s first commercial 5G New Radio (NR) radio for massive MIMO and Multi-user MIMO coming in 2017
  • New additions to Ericsson Radio System address key requirements of 5G, in today’s networks
  • Pioneering Industrialized Network Rollout Services solution facilitates complete rollout from configuration to verification in a single visit

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

  • Three new radios support Gigabit speeds for LTE and provide further flexibility in design: Radio 4407 and Radio 4412 enable 4×4 MIMO in one radio unit for FDD and TDD mode respectively, and Radio 8808 for advanced TDD beamforming applications
  • Addressing both the need for unlicensed spectrum options and the growing emphasis on small cells is the Radio 2205, a micro solution on unlicensed spectrum that is fully integrated in Ericsson Radio System, using the same baseband and network management
  • Two new baseband units support the growing need for densification: the outdoor micro Baseband 6502 and macro Baseband 6303 with Ericsson Rail System mounting for flexible site builds
  • Addressing interference issues in dense builds, Baseband P614 enables new band activation on challenging sites by mitigating Passive Inter Modulation, referred to as PIM mitigation, from static and dynamic sources both inside and outside the antenna system
  • Spectrum optimization is a growing need and Uplink Spectrum Analyzer is an Ericsson-unique software solution to remotely identify external interference without the need for costly measurement equipment and site visits
  • Exclusive to Ericsson is instant power sharing, used in the wideband Radio 2242. This capability allows power to be instantly shared between carriers, standards and bands, optimizing the use of radio resources
  • Cloud RAN will be an important 5G network architecture and Baseband C608 provides high-performance switching in Elastic RAN deployments

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.”

Introducing Ursa Straps – the Perfect Addition to the Radio Microphone Box

Now it’s not the usual field that we cover, but it hit our radar. How many times have you seen an enthusiastic presenter or an excited contestant on TV drop their radio mic and crawl around on the floor, trying to pick it up! Well when a costume designer and a sound man get together then things get designed, and why this hasn’t be invented before is beyond us, but it looks like an idea that could take off. Read the full article here.

Sound recordist Simon Bysshe and costumier Laura Smith have combined their knowledge and expertise to create URSA Straps, a unique range of low profile body worn straps designed to conceal radio microphone transmitters.

Introducing Ursa Straps – the Perfect Addition to the Radio Microphone Box

Officially launched this month and now available in the UK and Europe, URSA Straps are made from a specially developed bonded fabric that is ultra-slim and provides excellent stretch, comfort and breathability. Each strap incorporates a pouch to keep the transmitter locked in place and a cable pocket for managing excess microphone cable. URSA Straps are available in black, beige and brown skin tone colours and can be worn around the ankle, thigh or waist.

Bysshe and Smith developed URSA Straps after listening to numerous artists express discomfort while wearing radio mic straps. Traditional thick neoprene or elastic straps can irritate the skin, become soaked in sweat and are often impossible to disguise under figure hugging costumes.

“It was obvious that a better way of discreetly securing transmitters was required,” Simon Bysshe explains. “As a boom operator I had worked with many artists who disliked wearing transmitter packs because their associated straps could restrict movement and become uncomfortable. In some cases they had simply refused to wear them.”

Laura Smith’s knowledge of costume making proved invaluable as she was able to construct prototypes and identify the exact fabrics required to suit the needs of costume, artists and sound departments.

“After many months of research we decided to create our own unique hybrid fabric by fusing two stretch fabrics together,” Bysshe explains. “This resulting fabric is just 1mm thick and much lighter and softer than any other fabric of its kind. Crucially we incorporated a hook Velcro compatible outer surface that allows the straps to be securely attached to themselves at any point.”

Bysshe tested the new straps while working on the second series of Sky Atlantic’s The Tunnel. Lead actress Clémence Poésy was an immediate convert and provided valuable feedback to help develop the product. Bysshe has subsequently used URSA Straps on the third series of Peaky Blinders. The USRA Thigh straps were particularly popular with the cast members who found them secure, light and comfortable. The fact they can be worn around the thigh as opposed to the waist made them invaluable for use with the period costumes.

“With URSA Straps we have created such a comfortable low-profile solution that artists often forget that they are wearing them. Now we have to make sure that actors remember to take them off before they leave!” Bysshe adds. “The straps can be washed and re-used every day for many months. Our Thigh straps are particularly popular as they are designed to not slip down the leg. We achieved this by bonding on a strips of Polyurethane gripper to the inside of the straps.”

Outside film and television, URSA Straps are also proving popular with dancers who need to receive audio cues during a live performance. Using waist or thigh straps the sound team can easily conceal a receiver pack on their bodies without restricting movement or compromising the look of their costumes. URSA Straps have also developed a Double-Pack strap allowing artists to wear two packs on one strap.

Oscar-winning production sound mixer Simon Hayes was an early adopter of URSA Straps and describes them as a total game changer for his team.

“URSA Straps allow us to rig radio mics on costumes previously thought to be unmicable. Tight dresses, sportswear, stunt harnesses – they can all be easily miked using low profile URSA Straps. These straps are so popular with the actresses I work with that many have asked to keep theirs at the end of the production.”

URSA Straps are suitable for a variety of wireless transmitters including Lectrosonics, Zaxcom, Wisycom MTP40 and Sennheiser 5212. Two different pouch sizes are available to ensure optimum fit. Three different waist sizes are available: small, medium and large.

“Initially Laura and I were making the straps by hand in our garage,” Bysshe says. “When we realised their potential we scaled up production by taking on two experienced manufacturing firms in Leicester. Our launch has been a huge success with orders coming in from all around the world! We are now on our third large production run and expanding our market into Theatre, Concerts and Outside Broadcasts.”

Motorola Solutions Transforms Body-Worn Cameras for TETRA Users

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 “Smart Interface” (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.

“In Europe Middle East and Africa (EMEA), TETRA digital radio technology has become a standard for mission-critical communications,” said Steven Young, vice president TETRA devices at Motorola Solutions. “This 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 that´s unmatched in its ease-of-use.”

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:

  • The Si500 VSM is equipped with a 210-degree range-of-motion camera lens that provides optimal field-of-view and flexible wearing positions. Users can wear the VSM with the display facing in or out.
  • The Si500 VSM features a new adaptive audio engine that automatically adjusts audio settings based on the user’s wearing position and environment. With five integrated microphones and a loud 0.5-watt rated speaker, it provides the high audio quality of TETRA radios.

    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.

  • The Si500 VSM offers a full-screen tempered-glass display with an intuitive user interface that presents only vital information within three panels. Users have the ability to control radio channels and talkgroups, view recorded video and photos, tag videos and listen to audio recordings.

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:

  • Ensures end-to-end security that reduces any challenge to chain of custody for agencies

    Pairs with the Si500 VSM and can also operate stand alone and accept evidence gathered from any device

  • Offers a highly streamlined ability to search, review, annotate and perform other evidence management, reducing administrative time and expense
  • Provides an industry-leading auto-redaction feature to help public safety agencies remove identities of individuals in videos seamlessly. Instead of having to painstakingly invest the time to review and possibly edit each video frame, technicians will be able to automatically mark objects such as faces, addresses or license plates and let the new technology blur them out automatically throughout the video, saving hours of administrative time.
  • Creates greater engagement and transparency with communities. The system enables agencies to improve evidence sharing and more easily respond to content requests.
