1. A distributed network, spread-spectrum system, comprising:

  • a plurality of remote stations;

    a plurality of nodes for covering a geographic area, the plurality of nodes including a hub node, each node covering a micro-cell having a radius less than one mile, each node including, a spread-spectrum transceiver for communicating, using packets having spread-spectrum modulation, over radio waves, with the plurality of remote stations, each packet having a source address and a destination address;

    a store-and-forward subsystem, coupled to the spread-spectrum transceiver, for storing and forwarding one or more packets to and from the remote station, and for storing and forwarding the one or more packets to and from another node in the plurality of nodes;

    a flow-control subsystem, coupled to the store-and-forward subsystem, for controlling the store-and-forward subsystem, to store each packet arriving at the spread-spectrum transceiver, said flow-control subsystem communicating traffic information between each of the nodes in the plurality of nodes, with the traffic information including traffic density at each of the nodes, said flow-control subsystem, responsive to the traffic information and to a packet having the destination address to the hub node, for routing the packet through appropriate nodes to the hub node, said flow-control subsystem, responsive to the traffic at each node, each packet having a destination address to a first recipient node, for transmitting the packet from the hub node to an appropriate node, routing the packet to the first recipient node, said flow-control subsystem, responsive to the traffic congestion and to a plurality of packets having voice data, for routing the plurality of packets through a path in the plurality of nodes to ensure that the plurality of packets arrive sequentially; and

    said hub node, responsive to an information packet arriving from a central office, for routing the information packet to a second recipient node.
