    The UK is almost ready to flip the switch on its first LTE network, but it's determined to be at the forefront of the next-generation, setting up a "5G Innovation Centre" at the University of Surrey. The government announced it's putting up £11.6 million (around $18.6 million) in funding, but another £24 million (around $38.5 million) will be coming from an industry group comprising the likes of Huawei, Samsung, Telefonica, Rohde & Schwarz, Fujitsu and others. The money will allow research to go beyond concept and theory, with the aim that all partners work together to develop and standardize 5G technology, which the university has been looking into for a number of years already. They will focus on energy and spectrum efficiency as well as speed, and although it's early days, 10Gbps has been banded around as a per-tower target, translating to roughly 200Mbps for each connection. Unfortunately, we've also got a number to kill your geek buzz -- it's upwards of a decade away. Still, at least you've got a long time to think about which case you'll be picking up for your 5G-ready Galaxy S XV.

  • Rohde & Schwarz anechoic test chamber waves-on

    We're oft treated to fantastic news by the FCC while devices are tested in its immense labyrinth of labs, but what we've not seen much of is the type of equipment contained within them. While the smaller Rohde & Schwarz TS8991 that we had a peek at today is used more for antenna design purposes and not by the FCC, it still offers some interesting -- and frighteningly complicated -- insight into the world of those who make your handsets work. The MIMO test we watched involved two theta positioners (which can be seen in the picture above) that rotate about the handset on the pedestal which also turns to add the azimuth in the test run. Each theta positioner has a quad ridged horn antenna, which -- aside from likely being the greatest-sounding antenna name ever -- captures the signal from the handset and eventually allows the AMS32 management system to generate a 3D pattern of the radio emissions. The system will test 2G, 3G, 4G, WiFi and Bluetooth sets, and rings in somewhere above $1,000,000. Follow on for a video and a detailed explanation that is mostly user friendly.

  • Examiners use spectrum analyzers to bust cellphone-packin' cheats

    We don't see too many spectrum analyzers 'round these parts, and when we do the applications are usually pretty obscure. But catching cheating cheaters before they cheat again? That we can understand -- and apparently that's exactly what happened in Taiwan recently, when folks being tested for government jobs were overseen by folks packing a Rohde and Schwarz FSH4 spectrum analyzer. In addition to being a "closed book" test, this one was also a "closed phone" test, and the analyzers allowed examiners to listen for (and pinpoint the location of) mobile phone signals. As of right now, it looks like officials have uncovered three prospective cheaters, although additional evidence will have to be offered before a conclusion is made (perhaps they were just sexting). Can we offer a friendly word of advice? The next time you're taking a test somewhere, and the room is full of people outfitted with large spectrum analyzers and Secret Service-style earbuds, you'd probably want to take that as fair warning and turn off your celly.
