A radio communication system includes a remote device radio, and a base station radio operable to communicate with the remote device radio at a first channel and at a second channel using non-simultaneous frequency diversity. The base station is operable to communicate with a device other than the remote device at the second channel while the remote device radio and the base station radio are communicating at the first channel. A radio using non-simultaneous frequency diversity includes an antenna, a radio frequency module coupled to the antenna such that the radio frequency module is operable to transmit or receive radio frequency signals at a first channel and signals at a second channel using the antenna, and a baseband module coupled to the radio frequency module. The baseband module operable to transmit or receive signals through the radio frequency module, such that signals transmitted or received by the radio employ non-simultaneous frequency diversity using the first channel and the second channel. Additional devices are operable to use the second channel while the radio is transmitting or receiving radio frequency signals at the first channel.
