Abstract
A communication system (100) for dynamically selecting transmitters (115) for message transmission includes the transmitters (115) for sending transmission signals and a portable messaging unit (105) for receiving the transmission signals, calculating signal strengths of the transmission signals, and transmitting a signal indicative of the signal strengths. A controller (110) receives the signal and determines therefrom carrier-to-interference (C/I) values indicative of relative strengths of the transmission signals received by the portable messaging unit (105). Prior to message delivery, the controller (110) determines a selected transmitter (115) for transmitting a message to the portable messaging unit (105). The selected transmitter (115) is associated with a lowest C/I value that is chosen from the C/I values and that exceeds a C/I threshold value.
