Abstract:
1. A method of automatically selecting one or more transmission frequencies from five or more potential carrier frequencies, the method comprising: scanning the five or more potential carrier frequencies to determine a first signal strength indication of each of the five or more potential carrier frequencies; storing the first signal strength indication of each of the five or more potential carrier frequencies in memory; rescanning the five or more potential carrier frequencies to determine a second signal strength indication of each of the five or more potential carrier frequencies; choosing a first transmission frequency from the five or more potential carrier frequencies at least partially based on the first signal strength indication and the second signal strength indication of each of the five or more potential carrier frequencies; before choosing the first transmission frequency, removing a potential carrier frequency from the five or more potential carrier frequencies based on characteristics of one or more carrier frequencies adjacent to the potential carrier frequency of the five or more potential carrier frequencies; transmitting electrical signals on the first transmission frequency, wherein: the one or more transmission frequencies comprise the first transmission frequency; further comprising: after choosing the first transmission frequency, storing the second signal strength indication of each of the five or more potential carrier frequencies in the memory; rescanning the five or more potential carrier frequencies to determine a third signal strength indication of each of the five or more potential carrier frequencies; choosing a second transmission frequency from the five or more potential carrier frequencies at least partially based on the first signal strength indication, the second signal strength indication, and the third signal strength indication of each of the five or more potential carrier frequencies; and transmitting electrical signals on the second transmission frequency.
