1. A network for communicating a plurality of signals between a headend control office and a plurality of subscriber stations in full duplex, bi-directional fashion, comprising:

  • a. a headend control office containing headend signal processing circuitry for receiving a plurality of video signals from a plurality of video sources, and a plurality of digital signals from a plurality of digital sources, and transmitting said video and digital signals to a plurality of remote node transceivers via a network medium, and for receiving a plurality of subscriber signals from said remote node transceivers;

    b. a plurality of remote node transceivers coupled to said headend control office via said network medium, each of said transceivers adapted to receive said video and digital signals, and transmit said signals, via radiofrequency carrier in a first band of microwave frequencies comprising a range of between substantially 2500 and 2686 Mhz, and in a plurality of sectors, to a plurality of said subscriber stations, and to receive from said subscriber stations via radiofrequency carrier a plurality of multiplexed subscriber signals in a second band of microwave frequencies comprising a range of between substantially 2150 to 2162 Mhz, and transmit said subscriber signals to said headend control office via said network medium;

    c. a plurality of subscriber stations, arranged in cells, each cell of subscriber stations corresponding to one of said remote node transceivers, each of said subscriber stations comprising;

    1. a subscriber transceiver adapted to receive said radiofrequency-transmitted video and digital signals from its corresponding remote node transceiver and to transmit said multiplexed subscriber signals to said remote node transceiver via radiofrequency carrier;

    2. subscriber station signal processing circuitry adapted to couple said video and digital signals to video and digital input/output devices, respectively, and to receive subscriber signals from said input/output devices and couple said subscriber signals to said subscriber transceiver; and

    d. wherein a plurality of said subscriber transceivers are adapted to receive said radiofrequency-transmitted video and digital signals which are cross polarized with respect to radiofrequency signals which a plurality of other of said subscriber transceivers are adapted to receive.
