Full-Duplex Radio Integrated Circuit Could Double Radio Frequency Data Capacity

Zothecula writes Full-duplex radio communication usually involves transmitters and receivers operating at different frequencies. Simultaneous transmission and reception on the same frequency is the Holy Grail for researchers, but has proved difficult to achieve. Those that have been built have proven complex and bulky, but to be commercially useful in the ever-shrinking world of communications technology, miniaturization is key. To this end, engineers at Columbia University (CU) claim to have created a world-first, full-duplex radio transceiver, all on one miniature integrated circuit. Read more of this story at Slashdot.

The Difference Between Wi-Fi Security Protocols: WPA2-AES vs WPA2-TKIP

Setting up encryption on your wireless router is one of the most important things you can do for your network security , but your router probably offers various different options—WPA2-PSK (TKIP), WPA2-PSK (AES), and WPA2-PSK (TKIP/AES) among the alphabet soup. How-To Geek explains which one to choose for a faster, more secure home network. Read more…

New “Shingled” Hard Drives Hold Terabytes For Pennies A Gig

 While the last time most of us thought of shingles was when we were itchy in eighth grade, Seagate has been thinking of them as a way to store data. Called Shingled Magnetic Recording (SMR) Drives, Seagate’s new drives can store eight terabytes of data for about 3 cents a gigabyte. The catch? These are great back-up drives but they’re not very fast. At 5, 900 RPM and an average… Read More

How High-Tech Temporary Tattoos Will Hack Your Skin

Molly McHugh writes with this story about sensors that can be attached to temporary tattoos to monitor various medical information. “The Center for Wearable Sensors at the University of California San Diego has been experimenting with attaching sensors to temporary tattoos in order to extract data from the body. The tattoos are worn exactly as a regular temporary tattoo would be worn. The sensors simply sit atop the skin without penetrating it and interact with Bluetooth or other wireless devices with a signal in order to send the data….A biofuel battery applied as a temporary tattoo converts sweat into energy, and a startup within the center has developed a strip that extracts data from sweat to explain how your body is reacting to certain types of exercise. Amay Bandodkar, a fourth year PhD student at UCSD, explains that the sensors are programmed to react to the amount of lactate the body produces.” Read more of this story at Slashdot.

How the Rollout of 5G Will Change Everything

mrspoonsi writes The global race is on to develop 5G, the fifth generation of mobile network. While 5G will follow in the footsteps of 4G and 3G, this time scientists are more excited. They say 5G will be different — very different. “5G will be a dramatic overhaul and harmonization of the radio spectrum, ” says Prof Rahim Tafazolli who is the lead at the UK’s multimillion-pound government-funded 5G Innovation Centre at the University of Surrey. To pave the way for 5G the ITU is comprehensively restructuring the parts of the radio network used to transmit data, while allowing pre-existing communications, including 4G and 3G, to continue functioning. 5G will also run faster, a lot faster. Prof Tafazolli now believes it is possible to run a wireless data connection at an astounding 800Gbps — that’s 100 times faster than current 5G testing. A speed of 800Gbps would equate to downloading 33 HD films — in a single second. Samsung hopes to launch a temporary trial 5G network in time for 2018’s Winter Olympic Games.

Bidding In Government Auction of Airwaves Reaches $34 Billion

An anonymous reader sends word that the 2014 wireless spectrum license auction has surpassed $34 billion. “A government auction of airwaves for use in mobile broadband has blown through presale estimates, becoming the biggest auction in the Federal Communications Commission’s history and signaling that wireless companies expect demand for Internet access by smartphones to continue to soar. And it’s not over yet. Companies bid more than $34 billion as of Friday afternoon for six blocks of airwaves, totaling 65 megahertz of the electromagnetic spectrum, being sold by the F.C.C. That total is more than three times the $10.5 billion reserve price that the commission put on the sale, the first offering of previously unavailable airwaves in six years.” Read more of this story at Slashdot.

LibraryBox is an Open Source Server That Runs on Low-Cost Hardware (Video)

The world is full of wireless servers — or at least some of it is. There are still many places, including parts of the United States, where you can have all the laptops, smart phones, and other wireless-capable devices you want, but there’s no server that caters to them. Enter LibraryBox. It’s open source and it runs on a variety of low-cost, low-power hardware. The project’s website calls it “portable private digital distribution.” A lot of people obviously like this project and wish it well. LibraryBox ran a Kickstarter campaign in 2013, hoping for $3000, and raised $33, 119. But today’s interviewee, Jason Griffey, can explain his project better than we can, so please watch the video (or read the transcript) if you want to learn more about LibraryBox — including the story behind the project’s name.
