Problems solved by technology

A major factor adversely affecting the indoor performance of a radio-frequency (RF) wireless local-area network (WLAN) is multipath fading, where the signal reaching the antenna of a receiving modem is subject to distortion due to the superimposition of multiple versions of the transmitted signal propagated over different paths.
One manifestation of this distortion is that signals arriving by different paths are liable to cancel each other out, thereby attenuating t

Abstract

A radio frequency transceiver for a wireless local area network (LAN) may have two or more antennae. An active antenna that delivers a data-bearing signal having a signal quality at least as good as any of the antennae may be selected based upon measurements of the signal quality during a preamble field of data frames having a substantially longer preamble field than other data frames.
