The drone-based radio-over-fiber system (10) provides an unmanned aerial vehicle, AV, preferably a multi-rotor drone (12), connected to a base station (14) by a tether (18) including an optical fiber. A radio frequency-over-fiber system is used for bidirectional data communications between at least one radio frequency, RF transmitter at the base station (14) and at least one antenna (48A, 48B) mounted on the drone through the optical fiber in the tether (18). The system includes wave division multiplexers/demultiplexers that permit ultrahigh bandwidth communication over the tether (18). An embodiment of the system for 2x2 multiple-input, multiple-output, MIMO signals in the 700 MHz LTE band is described.
