Claim of US Patent No. 11,032,819

1. A method, comprising:receiving a modulated signal, by a system of a first network element of a distributed antenna system, the first network element including signal processing circuitry, wherein the modulated signal is in a first spectral segment, and the modulated signal conforms to a wireless signaling protocol;
converting, by the system, the modulated signal in the first spectral segment to a modulated signal in a second spectral segment based on an analog signal processing of the modulated signal in the first spectral segment that does not require digital signal processing and without modifying the wireless signaling protocol of the modulated signal in the first spectral segment, wherein the second spectral segment is outside the first spectral segment;
generating, by the system, fault mitigation messaging in a control channel, the fault mitigation messaging including test results for a back-up communication link; and
transmitting, by the system, the modulated signal in the second spectral segment and the control channel including the test results for the back-up communication link to a second network element of the distributed antenna system, the control channel further including instructions directing the second network element of the distributed antenna system to convert the modulated signal in the second spectral segment to the modulated signal in the first spectral segment.
