Researchers at Intel have developed a new technology that could address network performance degradation in wireless networks resulting from interference generated by devices like microwave ovens, cordless phones and baby monitors. The Spectrum Sensing technology enables a Wi-Fi radio to locate such interference and increase its signal to subdue the background noise. During early tests Spectrum Sensing was able to boost network speeds by 30 percent.

Speed may be the goal, but interoperability is the number one concern among 802.11n vendors and user-hopefuls. The 802.11n standard is hoped to achieve markedly faster transmission speeds with higher quality at longer distances and with less interference. Unfortunately, current 802.11n draft-compliant products have tested at less than desired levels, even coming short of results achieved by non-compliant products. Truly certified products are expected to be available the first half of 2007; early buyers are warned their 2006 purchases may not be compatible with the final version.

Chicago plans to spend $18.5 million to blanket the city in Wi-Fi so its citizens can easily access and afford the Internet. Approximately 7,500 antennas will be needed to create the wireless network, with access points mounted on top of city-owned streetlights and lamp poles as well as privately-owned sites. The city is looking for proposals offering low service rates and free service to schools and city parks.
