Abstract
A radio communication system (100) includes a terminal/controller (110, 112) for transmitting an enable signal, data associated with the enable signal, and a disable signal following the data. A normally operating transmitter (105, 107) coupled to the terminal/controller (110, 112) receives, when operating normally, the enable signal and transmits the data associated therewith as a radio frequency (RF) signal. The normally operating transmitter (105, 107) further generates status information for indicating that the normally operating transmitter (105, 107) is functioning, wherein the status information includes at least the enable signal and the disable signal. The radio communication system (100) further includes a redundant transmitter (115) coupled to the normally operating transmitter (105, 107) and the terminal/controller (110, 112) for receiving the status information and determining therefrom whether the normally operating transmitter (105, 107) is functioning. The redundant transmitter (115), in response to determining that the normally operating transmitter (105, 107) has ceased functioning subsequent to reception of the enable signal, automatically transmits the data asso…
