Broadband wireless signal covering network based on passive optical network structure

The invention relates to a broadband wireless signal covering network based on a passive optical network structure. The network comprises a first fiber power divider/wave combiner, a plurality of user terminal units, an optical wavelength multiplexing/de-multiplexing device, a second fiber power divider/wave combiner and a broadband photoreceiver, wherein the first fiber power divider/wave combiner allocates light carrier signals of a light emitter to a plurality of fiber power dividers; a plurality of the user terminal units correspondingly receive the light carrier signals of the fiber power dividers, emit the light carrier signals to air and receive user uplink RF signals through antennas; the optical wavelength multiplexing/de-multiplexing device collects user uplink optical signals of a plurality of the user terminal units and transmits the signals to the uplink direction; the second fiber power divider/wave combiner collects the user uplink optical signals and transmits the signals to the uplink directi
