4 researchers at the University of Washington leverage wireless signals to enable whole-home sensing and recognition of human gestures. It's called WiSee. Not WiWillSee. WiSee.

Wii and Xbox Kinect have a lot to answer for. The commercialization of gesture based interactivity might be taking a new step forward based no the work of Qifan Pu, Sidhant Gupta, Shyamnath Gollakota, and Shwetak Patel at University of Washington.

Wi-Fi chip pushes 1.7Gbps over four streams using 802.11ac standard

Quantenna today announced an 802.11ac Wi-Fi chipset that pushes 1.7Gbps of data over four wireless streams.

The first chips based on the 802.11ac standard hit 1.3Gbps last year by creating three streams of 433Mbps each. (With the older 802.11n standard, the maximum throughput for a single stream is 150Mbps.) Quantenna's QSR1000 chips based on 802.11ac are thus a minor evolution over what was already available, using Multi-user MIMO technology with four spatial streams to hit 1.7Gbps.

Wireless charging still has strings attached

As obviously useful as wireless charging is, it suffers from a Tower of Babel problem with incompatible standards and competing interests keeping it from truly going mainstream.

But the industry may yet be inching toward some level of sanity. AT&T is seeking from its handset vendors a commitment to one standard of wireless charging, CNET has learned.

DARPA seeks more robust military wireless networks

DARPA has created the Wireless Network Defense program, which aims to develop new protocols that enable military wireless networks to remain operational despite inadvertent misconfigurations or malicious compromise of individual nodes.

“Current security efforts focus on individual radios or nodes, rather than the network, so a single misconfigured or compromised radio could debilitate an entire network,” said Wayne Phoel, DARPA program manager.

Google is nearing a US$7 million (A$6.9 million) settlement with some 30 US states over a 2010 incident in which its Street View mapping cars collected passwords and other personal data from home wireless networks, according to a person familiar with the matter.

The announcement of the settlement is expected to be made by the states early this week, according to the person, though some of the final details of the deal were still being hammered out last Friday.

Fastest Wi-Fi ever is almost ready for real-world use

In a quiet suite removed from the insanity of the Consumer Electronics Show expo floor, a company aiming to build the fastest Wi-Fi chips in the world demonstrated its vision of wireless technology's future.

On one desk, a laptop powered a two-monitor setup without any wires. At another, a tablet playing an accelerometer-based racing game mirrors its screen in high definition to another monitor. Across the room, a computer quickly transfers a 3GB file from a wireless router with built-in storage.

The merger of cellular and Wi-Fi: The wireless network's future

Today we talk about 801.11ac, 4G, and LTE Advanced, but what users really want is just fast, reliable wireless networking that works everywhere. According to the experts, we're going to give it to them... eventually.

In a CES panel entitled "Six Wireless Technologies You'll Want to Know," the conversation quickly spun from being an overview of such technologies to how these Wi-Fi and cellular networking were coming together.

Apple addresses another Wi-Fi bug with iOS 6.0.2 update

Apple has released another minor OS update for iPhone, iPad, and iPod touch users aimed at fixing unnamed Wi-Fi issues. The 6.0.2 update began to appear in iTunes on Tuesday with no other description besides "Fixes a bug that could impact Wi-Fi," leading to speculation that the fix addresses an issue that caused some iPhones to drop their Wi-Fi connections and use cellular data more often.
