PACKETIZED VOICE AND DATA IN CELLULAR NETWORK

摘要

Distributed routing provides a robust, scalable communication system free of bottlenecks associated with traditional wireless systems. The system (20) includes subscriber units (26) sending and receiving information packets using wireless communication links (28). The system (20) also includes access points (22) with each access point (22) forming a coverage area (24) for exchanging information packets with subscriber units (26) within the coverage area (24). The system (20) further includes distribution points (40) receiving packets from access points (22). Distribution points (40) form a distributed routing network (41). Each distribution point (40) receives an information packet for distribution to a specified destination. If the destination is to a subscriber unit (26) within the coverage area (24) of the access point (22) in communication with the distribution point (40), the information packet is forwarded to the access point (22). Otherwise, the information packet is forwarded to one of the additional distribution points (40).
