A system and method for communicating on a network having multiple radios by substantially simultaneously transmitting a beacon signal from the radios. A broadcast signal is received substantially simultaneously by all of the radios and used to coordinate subsequent beacon signals. The broadcast signal may be from another of the same radios, or may be a broadcast signal from a television broadcast, global positioning system broadcast, or any other broadcast designed to reach several radios substantially simultaneously. The radios may normally operate by detecting another transmission and refraining from transmitting until the transmission has ceased. However, while transmitting synchronized beacon signals, the radios may broadcast simultaneously.
