| 摘 要： | 为实现在无线局域网络中达到与有线千兆以太网相同的数据传输率，应用了OFDM和MIMO及信道绑定等技术．然而在超高速无线局域网络的设计中，物理层的高速需要更有效MAC协议配合才能获得真正性能的提高．分析了高速无线链路下原有RTS／CTS竞争机制的制约效应，得出高速WLAN需要采用全双工通信方式来提高系统吞吐量．提出了三种基于AP信道资源调度管理机制的解决方案，分析了各方案的特点，为超高速无线局域网络的MAC设计提供理论依据．

| Abstract: | OFDM,MIMO and channel binding are applied in wireless LAN so as to achieve the equally fast data transfer rate as that in 1Gbps Ethernet network.However,high speed in the physical layer cannot be fully realized without a more effective MAC protocol cooperation in the design of super high speed wireless LAN.The restraint effect of the previous RTS/CTS competitive mechanism in the high speed link is analyzed,which brings about the conclusion that high-speed WLAN needs to elevate its throughput by adoption of ... |
