Abstract

A wireless communication device includes a polarity setting module configured to set a plurality of polarity modes for the wireless communication with the plurality of external devices. The plurality of polarity modes includes selected ones of at least: a first polarity mode, and a second polarity mode. The polarity setting module sets the plurality of polarity modes based on information received from the plurality of external devices. A framing module is configured to generate data for transmission to the plurality of external devices based on the plurality of polarity modes set by the polarity setting module.
