A network having multiple radios transmits a beacon signal from several
radios substantially simultaneously. One embodiment includes a network
having a communications backbone that connects several radio
transceivers. Another embodiment includes a single station having
multiple radio transceivers, which may or may not have directional
antennas. Various methods for synchronizing the beacon signals may be
used, including transmitting a heartbeat signal along the network so that
the beacon signals are broadcast substantially simultaneously.
