Research on Design Scheme of WLAN Communication Adapter Based on 802.11 Protocols

Abstract in the present mobile data transmission methods, only WLAN has the high data rate supporting video service, so it will necessarily be an important part of future personal communication networks. This paper researches into the characteristics and technologies of WLAN, analyses the properties and features of stochastic competitive MAC protocol, and designs a high-rate WLAN terminal card, which is based on IEEE802.11 protocol. The card applies Direct-Sequence Spread-Spectrum technology, can support a highest data rate at 11Mbps and meet the high-rate wireless access requirement.
