PROBLEM TO BE SOLVED: To provide a method, devices and a system for selecting an idle transmission frequency for transmitting electrical signals and for broadcasting the electrical signals by using the selected transmission frequency or other frequencies. SOLUTION: In some embodiments, a method of identifying at least one transmission frequency in a set of carrier frequencies can include: (a) determining a first signal strength for each carrier frequency in the set of carrier frequencies; (b) choosing a first transmission frequency from the set of carrier frequencies at least partially based on the first signal strength of each of the carrier frequencies of the set of carrier frequencies; and (c) broadcasting electrical signals by using the first transmission frequency. Other embodiments are disclosed herein. COPYRIGHT: (C)2009,JPO&INPIT |
