Possible bump ahead for wi-fi technology: slow speed devices

"French researchers say they have pinpointed a problem in wireless LAN technology that could severely impair the performance of newer high-speed networks.
Engineering experts at France's Centre Nationale de la Recherche Scientifique in Paris have demonstrated how a slow device connected to a WLAN hot spot can cause an entire network to drop to a slower speed, citing a common channel access method as the cause, said Andrzej Duda, one of the researchers, in an interview Thursday.

The researchers have focused on performance anomalies found in products based on the IEEE 802.11b standard. They observed that when one wireless device, such as a notebook, connects to a WLAN at a lower bit rate than other devices -- because it is too far from the access point, for example -- performance of the other devices on the network becomes noticeably degraded."
