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.

The 802.11n standard is imperiled because the Commonwealth Science and Industrial Research Organization has refused to submit a Letter of Assurance, promising not to sue those who implement the standard.
The realization that CSIRO holds essential patents, and has failed to provide a Letter of Assurance as required by the IEEE, could prevent the standard ever being finalized. This means that anyone who implements, or is implementing, 802.11n is at risk of being sued by CSIRO, and that the standard is very unlikely to be approved. As the internal memo, addressed to 802.11 Chair Stuart J Kerry, makes clear:

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.”
