Call transport alternatives for interconnected wireless communication networks based on IEEE 802.6 MAN

Anticipated growth in demand for personal communications services suggests that current facilities will not be adequate for handling the associated growth in message and signalling traffic. A new distributed switch architecture, consisting of an IEEE 802.6 Metropolitan Area Network (MAN) has been proposed, to interconnect wireless radio basesites with each other within a local region. Each MAN is then bridged to adjacent MANs, as well as to a backbone MAN for improved reliability and speed. Queue arbitrated (QA) access is provided to each MAN. A six-MAN network is simulated to determine the delay-throughput performance for both voice and data traffic, subject to voice traffic having priority over data. Of the 310 Mb/s capacity available, in the absence of signalling traffic, 290 Mb/s can be used, and provides source-to-destination transmission delays of less than 5 ms for up to 200 Mb/s of voice traffic
