摘　　要：摘要：首先介绍了工作在60GHz频段、支持1Gbit／s以上数据速率的IEEE802．15．3c标准和IEEE802．11a（1标准草案规定的无线接入机制的基本原理，然后对它们的特点和性能进行了详细的对比分析。研究结果显示：2种无线接入机制都采用了TDMA＋CSMA／CA的混合机制，但各有所长；IEEE802．11ad接入机制兼容性更好，能达到更高的数据速率，然而原理更复杂；IEEE802．15．3c接入机制实现相对简单，同样也能达到Gbit／s级别的数据速率.最后，对全文进行总结并指出了未来的研究方向。This paper first analyses the basic working principles of the wireless channel access mechanisms about the stand- ard IEEE 802.15.3c and the draft standard IFEE 802. l lad which are all working at the 60 GHz band and supporting the 1Gbit/s or higher data rates. Then, a comparalitive, analysis aboul the wireless medium access mechanisms charaeteristics and performances of the standard IEEE 802. 15.3c and the draft standard 1EEE 802.1 lad is made at leng＇th. The research stlows Ihat： bolh I EFE 802.15.3c and IEEE 802. l lad adopt the hybrid mechanisms： TDMA ＋ CSMA/CA; nevertheless, everyone has its own advantages. The access mechanisms of IEEE 802.11 ad have a better compatibility and can reach higher data rate, but the principles of IEEE 802. 11ad are more complicated than 1EEE 802. 15.3c. Meanwhile, the access mechanisms of IEEE 802.15.3e are simpler than IEEE 802. 11 ad and the data rate of IEEE 802. 15.3c can also reach Gbit/s. Finally, the summary and the direction of the future researches are given.
