Patent ID: 8509695

Claim:
A method of identifying at least one transmission frequency in a set of carrier frequencies using an electrical device, the method comprising: determining a first signal strength of each carrier frequency in the set of carrier frequencies using the electrical device; determining a second signal strength of each carrier frequency in the set of carrier frequencies using the electrical device; using the electrical device to choose a first transmission frequency of the at least one transmission frequency from the set of carrier frequencies based on the second signal strength of each carrier frequency of the set of carrier frequencies; and broadcasting electrical signals over the first transmission frequency using the electrical device; wherein: the at least one transmission frequency comprises the first transmission frequency; and determining the second signal strength of each carrier frequency in the set of carrier frequencies using the electrical device comprises: assigning the second signal strength of at least one carrier frequency of the set of carrier frequencies at least partially based on (i) a first received signal strength indication of the at least one carrier frequency of the set of carrier frequencies and (ii) the first signal strength of the at least one carrier frequency in the set of carrier frequencies.
