Abstract
A short range radio transmitter device includes a radio signal modulator and transmitter, a receiver and a controller coupled to the receiver. The controller and receiver operate to examine a frequency spectrum to select a transmission frequency for the radio signal modulator and transmitter. A receiver system for use with the transmitter includes a data channel service enabled receiver and a controller. The controller of the receiver system automatically tunes the data channel service enabled receiver to a frequency identified in a data channel service component of a received signal.
