NTIA says LightSquared proposal could pose national security threat

Last summer it looked like Philip Falcone's LightSquared was on the path to a democratic LTE solution: a coast-to-coast network, incorporating satellite connectivity to cover the entire country. It's an ambitious goal to be sure -- perhaps too ambitious. In a letter to the FCC, the National Telecommunications and Information Administration (NTIA) warned that the wholesaler's wireless network, which would operate on the MSS spectrum, could interfere with systems like Department of Defense communications. Here's the snag: last year the FCC approved the company's initial proposal to create a network that would incorporate both terrestrial and satellite services. Now LightSquared wants to offer the option of terrestrial-only phones to their clients. According to the NTIA, such a system would require far more land-based stations, causing potential MSS overcrowding and increasing the risk of interference with everything from aeronautical emergency communications to Federal agency systems. The FCC has yet to make a decision on the revised proposal, and LightSquared hasn't made a peep, leaving us to wonder whether it was all too good to be true.

Research shocker! Keyless car entry systems can be hacked easily, elegantly

We know you are vigilant enough not to trust your car's security to a wireless system, but plenty of other folks like the convenience of putting away the metallic keys and getting into their vehicles with a bit of Bond-like swagger. Professor Srdjan Capkun of ETH Zurich found himself perched on the fence between these two groups when he recently purchased a vehicle with a keyless entry system, so he did what any good researcher would: he tried to bypass its security measures. In total, he and his team tested 10 models from eight car makers and their results were pretty conclusive: each of the tested vehicles was broken into and driven away using a very simple and elegant method. Keyless entry systems typically work by sending a low-powered signal from the car to your key fob, with the two working only when they're near each other, but the wily Zurich profs were able to intercept and extend that signal via antennas acting as repeaters, resulting in your key activating your car even when it's nowhere near it. The signal-repeating antennae have to be pretty close to both the key and the car, but that's why heist movies stress the importance of teamwork. Hit the source link for all the chilling details.

World's first room-temperature semiconductor plasmon nanolaser created by Berkeley scientists

We're big proponents of the idea that everything is better with lasers, and a team of researchers at UC Berkeley has created a new type of semiconductor plasmon nanolaser, or spaser, that could eventually find a home in many of your favorite devices. The big breakthrough is that Berkeley's spaser operates at room temperature -- previous spasers could only sustain lasing at temperatures below -250° C -- enabling its use in commercial products. Plasmon lasers work by amplifying surface plasmons, which can be confined to a much smaller area than the light particles amplified by conventional lasers. This allows for extreme miniaturization of optical devices for ultra-high-resolution imaging, high sensitivity biological sensors, and optical circuits 100 times faster than the electronic variety. There's no word on how soon the technology will be commercially available, so you'll have to wait a bit longer for your first laser computer.

KFA2 NVIDIA GeForce GTX 460 WHDI graphics card is first to go wireless

What you're looking at is the world's first wireless graphics card affectionately dubbed the KFA2 (aka, Galaxy) GeForce GTX460 WHDI 1024MB PCIe 2.0. The card uses five aerials to stream uncompressed 1080p video from your PC to your WHDI enabled television (or any display courtesy of the bundled 5GHz WHDI receiver) at a range of about 100 feet. Otherwise, it's the same mid-range GTX 460 card we've seen universally lauded with 1024MB of onboard RAM helping to make the most of its 336 CUDA cores. Insane, yes, but we'd accept nothing less from our beloved graphics cards manufacturers.

Fujitsu unveils Esprimo FH99/CM, touts it as the world's first glasses-free 3D desktop

Source: http://www.engadget.com/2011/01/14/fujitsu-unveils-esprimo-fh99-cm-touts-it-as-the-worlds-first-g/

After seeing Sharp's 10.6 glasses-free 3D display last September, we left convinced that parallax barrier 3D technology was a long way off from being ready for prime-time, and then we reached for a bottle of aspirin. Demonstrations by Intel and Sony at CES this year proved, however, that a lot can change in four months, and we hope for Japan's collective eye sight that Fujitsu's Esprimo FH99/CM desktop PC follows this trend. That's because Fujitsu claims it's the world's first glasses-free all-in-one, and it's scheduled to launch in the country on February 25th with a whopping $3,100 price tag. All that dough will get buyers a naked-eye 23-inch full HD 3D display plus top-of-the-line features such as a Blu-ray drive with 3D Blu-ray support, a 2Ghz Core i7 processor, 4GB of memory, a 2TB hard drive, and two USB 3.0 ports. There's no word whether the computer will land stateside, but if it doesn't, Toshiba has hinted they could fill the void with a glasses-free 3D PC of its own by late 2011. Still, we wouldn't recommend stomping your 3D glasses just yet.
