The government is taking another look at the effect that wireless networks have on health.
The Health Protection Agency (HPA) has announced it will carry out “systematic” research into how wireless networks are being used.
The research will aim to establish average exposure to the low level radiation emitted by wi-fi access points and wireless links on computers.
The HPA said it expected the results of the research to be “reassuring”.

Wired Ethernet is not going to be replaced by 802.11n or any other wireless technology on the horizon anytime soon, if ever.
How do I make such a bold statement? Well, the facts really speak for themselves. The figure below is taken from the Wireless Performance Charts and show downlink throughput vs. path loss curves for three draft 11n products, representing the three major draft 11n chipsets.

With a planned $5 billion dollar build-out by Sprint, a growing ecosystem of WiMax device manufacturers, and some progress on the interoperability and standard fronts, the wireless technology is about to go public in a big way, according to the chipmaker.
We’ve been hearing about it for years, especially from Intel. WiMax will bring “true mobile connectivity.” WiMax will be a superior fourth generation network. WiMax will deliver broadband wireless internet service at speeds five times faster than 3G networks. And yet, despite all these promises, the mobile standard (IEEE 802.16) has remained a hyped concept instead of a viable option for the public at large.

Researcher David Maynor has published details of the controversial Apple Wi-Fi hack he disclosed at last year’s Black Hat conference.
Maynor had been under a nondisclosure agreement, which had previously prevented him from publishing details of the hack, but the NDA is over now and by going public with the information, Maynor hopes to help other Apple researchers with new documentation on things like Wi-Fi debugging and the Mac OS X kernel core dumping facility.”

A team of UK researchers is combining the power of social network Facebook with communications tool Bluetooth to learn more about human interactions.
Users register with the Facebook tool, called Cityware, that tracks encounters in the real world via Bluetooth. The project, which is backed by Nokia, HP Labs and Vodafone.
Researcher said:
“The really nice thing about Bluetooth is that when you are walking down the street, although you are not talking to anyone, your Bluetooth device can be talking to other devices.”
The team is also working on an application for virtual world Second Life.
