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 4x4 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."

To support new network builds, Ericsson has created the industry's first Industrialized Network Rollout Services solution. The Network Deployment Delivery Platform coupled with Ericsson's pioneering process facilitates the complete configuration, installation, integration, shakedown and handover of a fully verified site, ready in a single site visit.

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 â€" noise â€" 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 â€" although Seifer said they won’t be handing out pills at the door â€" 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 â€" these are good. The problem is that this is supposed to be fun!’

Icom America announces new series of NXDN IDAS mobiles and portables

The new range of Icom Radios, the 3400 and 4400 range. With a new colour screen and an SD card slot. Icom really are making strides in the radio market, We just hope that they keep the same connection types, so we can use our icom earpieces.

Icom America recently showcased a new series of multi-mode UHF/VHF NXDN IDAS radios that are designed to provide users with a flexible feature set and an enhanced user interface.

“It’s firmware upgradeable and licensed for different features,” Mark Behrends, senior manager of strategic sales at Icom America, said during an interview at the company’s booth during APCO 2016 in Orlando. “So, you pay for the basic radio, and you license up for the features that you want.”



While the next-generation IDAS radiosâ€"the 3400 series for VHF portables, 4400 for UHF portables, 5400 for VHF mobiles and 6400 for UHF mobilesâ€"continue to operate on the VHF/UHF bands with slightly more spectral range than previous models, this new series features a color screen, a “really intuitive” interface and greater software-upgrade flexibility, Behrends said.

“What it really changes is the user interface and the usability of the radio,” he said. “So, you can have conventional standard, or you can license up for Type D trunking or Type C trunking.”

Programming the radios can be accomplished via Bluetooth, a USB port and Icom’s standard connections, Behrends said. The Bluetooth functionality allows the radios to work with myriad accessories and third-party applications, he said.

Behrends noted that the new radios support secure-digital (SD) cards, which enable additional flexibility for users.

“An SD card is pretty handyâ€"you can record on it, you can capture GPS waypoints on it, you can program ICFS files and add new firmware through the SD card,” Behrends said.

Icom America expects this series of radios to be available this fall, after the products complete FCC testing, according to Behrends. Pricing will differ based on the type of screen included, but it generally will be comparable to Icom’s “higher-end IDAS product,” he said.

Where You Can Get a Walkie Talkie Headset

Walkie talkies are widely used in almost any setting where the portable radio communication is necessary, including but not limited to; loud environments, in forests, in airports, when hunting, in airports, hiking and other outdoor recreation, among others. The units come in handy in situations where many people need to listen, and only 1 needs to talk at a go, for instance, when giving instructions to workers on a camping site. In other words, Walkie talkies are a great communication tools to have, regardless of whether you're using them for fun, at home, or at work, to help in facilitating things to run smoothly. That being so, they have one major limitation, and that's the fact that they're hand held devices which you've to carry with you at all times, and handle whenever you want to communicate. If both of your hands are full, then that can be very inconvenient. Fortunately however, today, there lots of accessories you can use, such as the Walkie talkie headset, which frees up your hands, thus allowing you to talk or communicate with much ease. Moreover nothing helps enhance the audio quality of the Walkie Talkie more than the headset.



To use the headset, you simply need to plug it into the Walkie talkie, and then you can leave the unit clipped onto your belt. The headset will allow you to not only hear clearly, but it also helps in cancelling out noise from your surroundings or environment. The boom mic of the headset allows you to talk directly into the Walkie talkie without having to hold the device up near your mouth.

Radio Connector Types

Walkie talkies don't use the same types of connectors for attaching the speakers, earpiece/microphones or headsets. Today, there are many different connector types available on the market. Even different Walkie talkie models from the same company might have different connector types. Actually, just because 2 different radios have a same physical connection socket, doesn't always mean that they're internally wired up the same way; this means that you should never assume that having the same socket means similar accessories will work in both Walkie talkies. So always be careful when choosing the connectors for your radios.

Active vs Passive

The Active Walkie talkie headsets normally manage the ambient sound that's around it, and send a similar frequency to unwanted sounds to cancel it out; this increases the sounds to noise ratio of unwanted sounds, eventually cancelling the noise out. The Passive Walkie talkie headsets rely on the insulated or the sound absorbent material to muffle the sounds; this is a cheaper option which only protect ups to a certain decibel level.

Conclusion

Today, there is a wide range of walkie talkie headsets to choose from. Your choice should depend on your particular needs, however, you should also make sure you choose one which will work great in your particular ambiance. If you are looking to buy a Walkie talkie headset, contact Headsetonline today, and we will gladly provide you with the perfect unit geared to meet each and every one of your needs.

what to look for when buying earphones

Closed Back Headphones vs. Open-back Headphones

Open-back headphones have pads which rest on the outer ear. They're designed such that the outer shell of the ear cup has perforations usually with horizontal cutouts. The Open back headphones design of the ear cup enhances better natural sound because of less coloration as compared to the Closed back headphones.

Closed back headphones have much larger earpads which encircle the ears. They are designed such that there's a big pad which cups the ears, and it features an insulated outer shell of plastic which covers the ears. The Closed back headphones actually have a very solid outer shell which doesn't have any sort of perforations such that the outer shell effectively cups/encircles the entire ear. The Closed back headphones are excellent at isolating noise. They block most of the ambient noise, but they've a smaller sound stage, which gives the user the perception that the audio/sound is originating from within their head. Closed back headphones also tend to produce much stronger low frequencies as compared to Open back headphones.

Low Impedance vs High Impedance



Headphones normally come in various different impedance levels, such as 8 ohms, 16 ohms and 32 ohms. The power that's supplied by an audio source may be at varying levels because of a variety of factors including being limited because of being battery powered. Generally, as the impedance of the headphones increases, much more voltage will be required in order to drive it, and the audio loudness of headphones for a particular voltage decreases.

The determination of impedance is usually disregarded by many headphone buyers, however, the truth is it's one of the most important factors to consider when choosing the best headphones for your particular needs. Impedance is basically just how much power the headphones can put out so that it can overcome resistance to move the headphones' diaphragm.

Low impedance headphones (that is, less than 25 ohm), usually require little power in order to deliver high audio levels. Low Impedance headphones play well with devices which have weak amplification. These can include; mobile phones, portable music players and various other portable devices. This type of headphones can be used at home and also while jogging with your mobile phone; this is one of the reasons why most of the on-, in-, and over the ear headphones, are low impedance. Low impedance headphones are normally designed to get plugged directly in to a single (one) source, and generates sound more efficiently from a lower level input signal. This headphones tend to be much louder and much more efficient, however, they will also require a much more capable amplifier.

High impedance headphones (25 ohms and above), generally require more power in order to deliver high audio levels. As a result, they're protected from damages caused by overloading. High impedance headphones are typically designed for studio like applications where there might be multiple phones/devices wired in parallel and receiving input signals from a single source. High impedance headphones are more tolerant of the amplifier limitations, however, they will produce less volume for a particular output level. They are also a little more durable (that is, electronically), however, they require much higher signal levels in order to produce the same level of output level of the low impedance headphones. This type of headphones can be used with a wider range of audio equipment.

Passive Headphones vs. Active Headphones

Passive (noise cancelling) headphones are made of materials which help in blocking out sound waves from the surrounding environment. The same way ear muffs soften the outside noise, so does this type of headphones employ passive noise canceling. This type of headphones are typically used for both professional mixing and monitoring, like in broadcast and recording studios, and such other applications. Passive headphones are basically designed to playback music/audio true to the actual original recording, with minimal, compression, EQ, and such other sound enhancements.

On the other hand, Active headphones use batteries in order to power the built in Digital Signal Processing (also abbreviated as DSP) technology which processes play back for a particular reason, for example, to enhance the bass and the high end. Due to the enhancement of playbacks with sharper high ends and more bass, active headphones are more popular for general listening and listening to music for pleasure. Active noise cancelling headphones are also made of materials which help in blocking out outside noise, however, they take things a step further by making their very own sound waves; the sound waves created mimic the outside noises, but are a mirror image of each other, thus cancels each other out.

Wired Headphones Vs Wireless Headphones

When choosing a pair of headphones, deciding between wireless vs. wired is among one of the most overlooked factors. Wireless headphones might be a more popular choice, however, the wired headphones also have their own set of benefits. Well, that being said, as a general rule of thumb, between wireless headphones and wired headphones, assuming a similar price between the models; the wired headphones usually offer a much better quality. Also, the audio quality may get compromised over Bluetooth.

You can opt for the wireless headphones if you are not much of an audiophile, and you tend to travel a lot. If you really don't like getting the cables of your headphones getting tangled, or caught while listening to music/audio, then the choice should be rather simple; go for wireless headphones.

You can opt for the wired headphones if you are an audiophile, and you do not necessarily bother with the wireless options unless absolutely essential like using them when traveling, or keeping the headphones as a backup. As aforementioned, the wired headphones are way ahead in terms of output quality as compared to the wireless headphones. You will never have to worry about running out of batteries, unless you happen to opt for wired headphones which cancel noise. In addition, you will never suffer from interference from the other commonly used wireless electronic devices. However, you will need to take good care of the wired headphone cables, or they will eventually break.

Intel Made A VR Headset And It's Totally Cord-Free

Intel just announced its own virtual reality headset called Project Alloy, a VR competitor to the Oculus Rift,HTC Vive and the forthcoming PlayStation VR headsets. But what separates the Alloy from the pack is that it’s completely wireless (the wire above is for capturing video for the demo) and it should give you complete spatial awareness without all the dongles the Rift and Vive currently require.

It does this using two of Intel’s RealSense cameras to continuously map your environment. It can even map your hands.

Intel calls the idea “Merged Reality”, essentially combining inputs from cameras around your environment into a virtual world. And Intel was able to pack everything â€" the processor, sensors and controllers â€" into one cord-free headset.



During Intel’s demo, however, the RealSense camera didn’t seem quite as fluid as you’d hope, especially if it’s your primary means of reacting to the digital world around you. Intel says that its hardware will be open source in the second half of 2017 (ugh), so the headset won’t be available anytime soon. Intel is also working with Microsoft so Alloy can run Windows Holographic, the software which powers Hololens, according to Microsoft’s Terry Myerson. Microsoft says that Windows Holographic will also be released in an update for all Windows 10 PCs next year.

Ham radio: A last resort when phone lines fail

We at this blog believe in radio communications and will never let it die, understanding the importance that it still plays, and during the worst catastrophes, will be the best form of communication. This story about 9-11 adds proof to this statement.

If disaster strikes, there is a form of communication that can still get through: a ham radio.

When 9/11 hit New York City in 2001, for instance, ham radio operators provided a connection to the outside world.

One of those people was amateur radio enthusiast Bob Kyvig, formerly of White Bear Lake, who now lives in Centerville.

“The only communication out there on 9/11 was amateur radio,” Kyvig recalled. “The telephone lines were jammed and no one was going in or out.”

On the days following that horrific attack, Kyvig assumed the role of messenger, relaying messages from Manhattan to loved ones in the area by calling or knocking on their door. His house calls would go like this: “I am Bob; I am a ham operator. I just communicated with your loved one; they are fine and doing well and they will talk to you soon.”

When White Bear Lake sailor Gerry Spiess landed in Samoa on his historic solo voyage across the Pacific Ocean in 1981, he contacted Kyvig, who connected Spiess with his wife Sally.

When Hugo’s tornado struck in 2008, he and wife Jill remained on the radio as long as they could but had to abandon the “ham shack” as the storm approached. The tornado did $30,000 damage to their home, including Kyvig’s outside antennas.



A ham since 1968, long before Facetime, email or Skype, Kyvig was 20 when he took up the hobby while serving in the Navy. He was stationed in Hawaii and had childhood buddies serving in Germany and aboard the USS Milwaukee. The three met on the radio at least once a week without fail for more than 40 years, until the death of one of the men in 2015.

That connection to people is what Kyvig most enjoys. He chats on the radio to people he’s never met around the world.

“It’s a worldwide network of people enjoying fellowship with other hams,” Kyvig said.

The radio operator answers calls for help in areas of “health and welfare,” and was on Centerville’s first CERT (citizen emergency response team), which is now inactive. He serves as a severe weather spotter too, and gains “insights” as to what is happening around the world by chatting to foreigners.

“We talk about everything from fishing, to weather and local problems,” he said. “It’s very interesting because you find out so much about people across the world. And it’s not just the personal part but handling messages for help in disasters.”

He’s listened to astronauts aboard the space station and scientists at the South Pole. He has talked to people in Russia, New Zealand and most of Europe. For a long time, he kept a conversation going with a man in Norway who lived close to some of his relatives. Wife Jill also has her ham license and enjoys talking to other women, known as YLs or young ladies, across the world. “Lord knows what they’re talking about,” Bob said. “I leave the room.”

Ham buffs do have opportunity to meet at events called “eyeball picnics.” The Kyvigs traveled to a picnic in Branson, Missouri earlier this summer to socialize with other hams and match voices with faces.

Without getting too technical, Kyvig explained that radio signals are bounced up through the ionosphere. The signal goes up and down several times before it hits the final destination and you don’t control where it hits. People who want to contact Kyvig can tune into his call number: WA0ROH, assigned by the Federal Communications Commission (FCC), which regulates interstate and international communications. The agency requires operators to keep a log of who they talk to on an electronic spreadsheet.

“We could be talking to people the FCC thinks is a bad guy,” he said. “Because we can transmit all over the world without a phone line, some use it to their own means.”

Other countries have comparable agencies.

Each country has its own beginning call letters. The United States uses W, K and N.

“The concept is simple,” he added. “We use what Mother Nature has provided: airwaves. We plug a number in for a country and anyone can answer.”

A true party line, Kyvig said 30,000 people could be listening in on a conversation.

Jill proudly pointed out that Bob earned a master’s degree from The 3905 Century Club. It’s not the typical academic degree, but a difficult achievement nonetheless. “The degree was a challenge,” he said, which explains why only 68 radio operators have received the degree since 1967.

Bob inspired her to get her license, Jill said, and together they do public service events using ham radio.

Invented in the early ’20s, ham equipment is evolving, but affordable. Newbies can do it for about $300, he said. There are antennas on his roof, but mostly they are horizontal wires stretched between a tree and the house. Generator backup is used if there’s a power outage. He also keeps a mobile 12 volt transmitter that he can use in his truck to chat while he’s driving.

At one time, working knowledge of Morse code was a requirement to get an FCC ham license, but that was dropped, so more people are getting into it, he said.

When he’s not on the radio, Kyvig enjoys making furniture and fixing TVs. He retired from a career in computer operations about five years ago.
