1. A communications system comprising:

  • a plurality of network nodes and communications links that link said network nodes to form a high bandwidth backbone network, wherein at least one of said communications links forms a point-to-multipoint communications link between two network nodes;

    at least one of said network nodes having a point-to-multipoint remote device at one end of the point-to-multipoint communications link;

    at least one of said network nodes having a point-to-multipoint sector transceiver at the other end of the point-to-multipoint communications link for transmitting data in a sectored point-to-multipoint downstream communications link with remote devices including the linked point-to-multipoint remote device at the network node and receiving data from the point-to-multipoint remote device at the network node in a point-to-multipoint upstream communications link.
