Abstract
A wireless communication system uses transmitted data signals to monitor and control redundant modulator hardware. A modulator unit signature identifying the modulator unit currently transmitting data is embedded into each data frame carried by the transmission signal. Each modulator unit can then independently monitor the transmission signal to determine which modulator is currently transmitting data. Each modulator unit then monitors the transmission signal in case the modulator unit actively generating the transmission signal fails. In a failure situation, the active modulator unit disconnects itself from the transmission circuity while the backup modulator unit independently connects to the transmission circuitry to begin active transmission.
