An enhanced wireless local area network architecture

This paper introduces and describes the theoretical performance for an enhanced wireless LAN architecture, referred to as the hybrid wireless LAN (HYWLAN) architecture, that incorporates, a receiver-directed distributed control protocol. The HYWLAN architecture is compared to a popular wireless direct sequence spread spectrum CSMA/CA LAN architecture and an alternative HYWLAN architecture, and shown to be superior to both. The HYWLAN architecture provides flexible use of the allotted bandwidth and minimization of mutual user interference through uniform distribution of the offered load across both frequency and code space. It supports secure, mobile, line-of-sight (LOS) packet and circuit-based communications with minimal set-up overhead and without any service charges. The HYWLAN architecture also supports a large user base compared to the direct sequence spread spectrum CSMA/CA LAN architecture and the largest combined throughput of all the alternative architectures considered, rendering it the most effective for supporting mobile LOS applications
