ABSTRACT:
A method for packet signalling between a base station with a variable antenna system and remote stations uses pilot tones sent by the remote stations to the base station at the start of each data transfer period in which signalling will occur in either direction. The base station uses the pilot tone to configure the directional antenna for communication with the remote station during that data transfer period. The pilot tone signals are initiated by polling signals and polling acknowledgment signals.
