A MAC protocol for a wireless LAN based on OFDM-CDMA

Local access encompasses requirements of high throughput, transfer performa nce, flexibility, and ease of user/terminal mobility at a relatively low co st. While some of these targets can often be met satisfactorily with wired infrastructures, it is getting increasingly popular to resort to wireless a ccess (wireless LAN), mainly because of its simpler deployment, continuous coverage, availability of ad hoc connectivity, and user/terminal mobility s upport. This article outlines the proposal of a broadband quality-oriented WLAN system. The basic system characteristics are described, with details g iven on a MAC protocol supporting IP and exploiting an OFDM-CDMA technique.
