Abstract
Technologies for implementing and utilizing a redundant data bus for the reliable transmission of data between communication endpoints are provided. A redundant data bus includes two or more transmitters configured to transmit the same data signal in separate frequency bands over twisted-pair wiring to corresponding receivers. A data signal containing input data received at an input communication endpoint is generated and the data signal is simultaneously transmitted through the two or more transmitters over the twisted-pair wiring to the corresponding receivers. The data contained in the data signals received at the receivers is validated, and output data is extracted from a valid data signal and made available at an output communication endpoint, while any invalid data signals are ignored.
