Distributed routing provides a robust, scalable communication system free
of bottlenecks associated with traditional wireless systems. The system
includes subscriber units sending and receiving information packets using
wireless communication links. The system also includes access points with
each access point forming a coverage area for exchanging information
packets with subscriber units within the coverage area. The system
further includes distribution points receiving packets from access
points. Distribution points form a distributed routing network. Each
distribution point receives an information packet for distribution to a
specified destination. If the destination is to a subscriber unit within
the coverage area of the access point in communication with the
distribution point, the information packet is forwarded to the access
point. Otherwise, the information packet is forwarded to one of the
additional distribution points.
