Abstract

A common signaling method are apparatus are provided. In one embodiment, a method is provided that enables communication in under-utilized radio frequencies by receiving a master beacon, scanning radio frequencies included in the master beacon, and establishing communications using an unoccupied radio frequency from one of the listed radio frequencies. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Claims

1. A method of communication, the method comprising the steps of:

scanning a plurality of radio frequencies for a master beacon signal;

receiving the master beacon signal that includes a list of radio frequencies;

scanning the list of radio frequencies for an unused radio frequency;

transmitting a signal on the unused radio frequency;

transmitting a local beacon signal;

periodically scanning the plurality of radio frequencies for the master beacon signal;

detecting the master beacon signal;

ceasing transmission when a priority signal is included in the master beacon signal;

monitoring the master beacon signal; and

transmitting when the priority signal is absent in the master beacon signal.

2. A method of communication, the method comprising the steps of:

scanning a plurality of radio frequencies for a master beacon signal;

failing to detect the master beacon signal;

scanning the plurality of radio frequencies for an unused radio frequency;

transmitting a signal on the unused radio frequency;

transmitting a local beacon signal;

periodically scanning the plurality of radio frequencies for the master beacon signal;

detecting the master beacon signal;

ceasing transmission when a priority signal is included in the master beacon signal;

monitoring the master beacon signal; and

transmitting when the priority signal is absent in the master beacon signal.
