Abstract
Radio-over-fiber (ROF) antenna extender systems and methods are disclosed for high speed train communications which utilize cellular networks as backhauls to avoid the expensive capital expenditure involved in providing broadband Internet services in high speed trains. Employing ROF technology, on-roof antennas are deployed in strategic configurations to address the drawbacks of utilizing cellar networks as backhauls. The systems and methods provide broadband Internet service to a train and include a plurality of antennas mounted to an exterior of the train and operable to communicate with a cellular network, wireless access points mounted to the train, and a control system operably coupled to the plurality of antennas and to the wireless access points, wherein the control system is operable to receive and process data received from the plurality of antennas and the one wireless access points.
