Abstract
A dual mode transmitter/receiver adds two-way radio functionality to a frequency division duplex mobile phone. The dual mode transmitter/receiver allows short-range and low-power communication between similarly equipped phones. In the two-way radio mode, the dual mode mobile phone transmits and receives at a frequency between the normal mobile transmit and receive frequency bands so that a number of transmitter/receiver components are utilized for both normal and two-way radio communication.
