METHOD AND SYSTEM FOR SELECTING, TRANSMITTING, AND RECEIVING AN UNUSED CARRIER FREQUENCY AND TRANSMITTING OVER THE UNUSED CARRIER FREQUENCY

摘要

Some embodiments concern a method of transmitting electrical signals. The method can include: using a global positioning satellite receiver to determine a first location of a first electrical device; using a first transmitter to transmit the first location to a first server; using a receiver to receive information identifying at least one first unused frequency at the first location from the first server; selecting a first transmission frequency from the at least one first unused frequency; and communicating the first transmission frequency to a user. Other embodiments are disclosed in this application.
