Circuit based data transport for a wireless access communications system

The interest in wireless data communications has been increasing, in part due to new wireless communications services and the availability of the portable data terminals such as notebook computers. This paper describes a Go-Back-N automatic repeat request (ARQ) radio link protocol for data transport over a TDMA/TDM Wireless Access Communications System (WACS). The paper investigates the throughput performance as a function of message length, signal-to-noise ratio and fading rate. Results show that 88% efficiency is achieved for signal-to-noise ratio exceeding 18 dB. This work is targeted towards understanding the implications to local exchange networks of wireless technology alternatives that could provide access to those networks.
