Abstract

In packet based wireless LAN systems operating at microwave radio frequencies, the actual rate of successfully decoding any particular packet at a single receiver may be quite low. This is due to poor attenuation and multipath characteristics of the employed microwave radio channels. This performance is particularly degraded when penetrating buildings. In some areas the coverage from all available Access Points may be marginal, so handoff to better cells may not result in better performance. Also, in the case of many multimedia applications, the delays introduced by retries may be unacceptable.
