G2 Microsystems has pioneered a new technology that will allow devices like headphones, speakers and other WiFi devices to directly communicate with notebooks Intel Centrino 2 chips. The company’s WiFi networking module can be planted inside consumer devices to allow them to connect to Intel My WiFi-enabled computers without the use of access points.
The technology promises to make tasks “such as wireless printing and synchronization between a digital photo frame and your photo archives” less onerous, according to the company’s founder and CEO Geoff Smith.
With the advent of Intel My WiFi Personal Area Networks, made possible by G2 Microsystems, WiFi has sneaked into Bluetooth’s territory.
Did you know that more Wi-Fi networks are out there than what your computer can normally see? It's true. But depending on the security settings of the wireless network and its overall signal strength, you might not see these alternate options pop up in the standard Windows network settings dialogue. That's where Wi-Fi scanning applications like NetStumbler or inSSIDer come into play. That, and they're the best way you go about cataloging all the hotspots in your neighborhood from the passenger seat of your moving vehicle.
Click the link, and we'll show you how you can use inSSIDer to find out valuable information about the wireless networks floating around you right now!
When we reviewed Eye-Fi’s original wireless SD card (March 2008), our verdict was that this device, which lets you automatically upload images to the Internet via Wi-Fi, was a cool gee-whiz item hurt by a number of flaws. This update fixes those weaknesses and turns this wireless card into a must-have item for photo-sharing.
Election Day wasn't the only event to make history on November 4th - the FCC made its own kind of history on Tuesday in approving the development of wireless devices that can use "white space" (the unused broadcast TV spectrum between broadcast TV channels, which ranges from 512MHz to 698 MHz). Unlike the close race between fellow senators for the US Presidency, the FCC decision to open up unused TV spectrum was unanimous, ZDNet's Sean Portnoy reports, despite lobbying against the rule by 50 members of Congress and a variety of recording artists worried about the effects of the decision on their live performances.
The decision (available here in PDF format) balances the hopes of companies like Microsoft and Google to make wireless Internet-enabled devices even more ubiquitous than now with the fears of the theater industry that exploiting white space will interfere with wireless microphones that use the same spectrum, and the concerns of the National Association of Broadcasters that using "white space" will interfere with TV viewing.

The mini-ITX form factor is still alive and kicking, and to prove it, Zotac has just expanded its mini-ITX lineup with the nForce 630i-ITX WiFi motherboard. As the board's nomenclature suggests, WiFi comes integrated with 802.11b/g support, as does graphics chores, which are handled by Nvidia's GeForce 7100 chipset.
The pint-sized board comes ready for Intel's lineup of Core 2 Duo and Core 2 Quad processors with support for a full 1333MHz frontside bus. RAM support, on the other hand, comes somewhat gimped topping out at DDR2-800 instead of DDR2-1066 or DDR3. Other features include:
Eight USB 2.0 ports (four on back panel, four on pin header)
Onboard 10/100 Ethernet
HD Audio 5.1
Dual display ready (VGA / DVI)
Four SATA II ports with RAID Support
Not a bad feature-set for a compact board, particularly if you're in the market for an HTPC build, where the integrated WiFi could end up a major selling point.
When it comes time to shop for a videocard, most people are concerned about the pixel pushing power and how well a new GPU can handle Crysis. Yet others are more concerned with a videocard's ability to fit into a home theater PC setup, both physically and functionally. Some GPUs are even sought after for their ability to fold proteins, but apparently there's another use emerging, one with malicious intent.
According to Global Secure Systems, a Russian firm used Nvidia GPUs to break through WPA and WPA2 encryption. Assuming the report is accurate, the implications are nothing less than frightening, as GSS claims the brute force attack managed to accelerate WiFi 'password recovery' times by up to 10,000 percent.
"This breakthrough in brute force decryption of WiFi signals by Elcomsoft confirms our observations that firms can no longer rely on standards-based security to protect their data," noted David Hobson, managing director of GSS. "As a result, we now advise clients using WiFi in their offices to move on up to a VPM encryption system as well."
But even moving to a VPN may not be enough, as many VPNs use AES encryption just like WPA2. And by throwing videocards into the mix (it remains unclear which specific Nvidia GPUs were utilized), accessibility quickly becomes a growing concern.
Does this latest attack concern you? Hit the jump and post your thoughts.
Wi-Fi is fast emerging as the most popular technology for wireless communication between disparate gadgets, but security remains a major concern. However, researchers at Boston University’s College of Engineering are working on an alternative way of connecting devices that will be innately more secure than Wi-Fi.
Moreover, an LED-based communication technology will enjoy a distinct security advantage. It will be more secure compared to Wi-Fi due to the inability of light to penetrate through opaque surfaces like walls.
“Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires,” said an ebullient Thomas Little, a BU engineering professor, about the idea. Soon, our networks will quite literally “light up”.
A study by market research firm In-Stat has found that our dependence on wires is rapidly waning with the rise in the sales of embedded Wi-Fi devices. The study pegged the sale of embedded Wi-Fi devices around the world at 294 million units in 2007. It expects the figure to leapfrog to 1 billion by 2012.
According to the study, Wi-Fi enabled cell phones will usurp PCs as the most popular (largest) category of Wi-Fi devices. Even digital TVs are expected to interact with a wide gamut of devices using Wi-Fi in the imminent future. As Wi-Fi marches towards ubiquity, there are some compatibility and security issues that need to be addressed urgently.
Commercial wireless systems, which top out at hundreds of megabits per second, still have a ways to go before being on the level of optical fiber, which boasts tens of gigabits per second. Looking to close that gap, engineers at Battelle, a research and development firm based in Columbus, OH, have found a way to send data through the air using millimeter-wave technology.
Achieving faster speeds by harnessing the millimeter-wavelength frequency of the wireless spectrum isn't new, but it is both expensive and complex due to the equipment involved to generate the signal. Or at least it used to be. The Battelle team has taken off-the-shelf telecommunication components and, by modulating data on two low-frequency laser beams, has been able to create a pattern of interference that acts as a 100GHz signal (millimeter-wave technology operates on frequencies between 60GHz and 100GHz). By doing so, the team demonstrated a 20 gigabit-per-second signal in its lab.
While the research looks promising, a shipping product could still be years away. Putting the system together using existing components has helped to break through the cost barrier, but the new challenge will be to create a smaller device that's less unwieldy.
This multi-function Wi-Fi device is super handy in some applications; utterly useless in others. It’s great if you have an extensive hardwired network and want to deploy a wireless access point and a three-port switch in a room your Wi-Fi router can’t otherwise reach. But it sucks as a wireless bridge because of its extremely poor range.
