摘要
802.11n协议继承并改进了802.11协议物理层和媒体接入控制(MAC)层技术,提升了无线吞吐量。但是,面对复杂的室内环境,周围存在无线干扰的情况下,无线吞吐量必会受到影响。本文在楼宇办公环境中实测速率为300 Mbps和450Mbps的802.11n无线网络吞吐量,对比二者在20 MHz和40 MHz带宽下的吞吐量性能,并分析在Android、Windows7和WindowsXP系统下的不同客户端的吞吐量状况,为在楼宇环境下进行802.11n无线局域网的部署提供了有效的参考。
Inherited and improved the physical layer and media access control （ MAC） layer technology of 802.11, 802.11n wireless protocol improved throughput.However, facing with a complex indoor environment and radio interference around, the wireless throughput will be affected.In this paper, the wireless network throughput of 802.11n with the rate of 300 Mbps and 450 Mbps are measured and compared in an office environment with different bandwidth of 20 MHz and 40 MHz.What＆#39;s more, the throughput of the different clients with Android, Windows7 and Windows XP systems are analyzed.The result provides an effi-cient reference for 802.11n wireless LAN deployment in the building environment.
