摘要
随着智能移动设备的普及,目前Wi-Fi被大量地部署在用户大密度聚集的大型场馆,然而实际情况中时常出现网络性能不佳的问题。针对西南某高校图书馆Wi-Fi网络的实际情况,借助Acrylic Wi-Fi系列测量工具从网络覆盖、信道分配、传输性能等方面进行了实地测量与分析。并将测试的结果与802.11协议内容,特别是其中的CSMA/CA协议结合分析,发现了该网络性能不佳的问题,提出了提高该网络性能的方法,给其他场馆Wi-Fi的实际部署提供了参考。
With the popularity of smart mobile devices,Wi-Fi is currently developed in large venues where users are densely populated.However,in practice,poor network performance often occurs.According to the actual situation of the Wi-Fi network of a university library in Southwest China,the Acrylic Wi-Fi series measurement tools were used for field measurement and analysis from the aspects of network coverage,channel allocation and transmission performance.Combining the test results with 802.11 protocol content,especially CSMA/CA protocol,the problem of poor performance of the network is found,and the method of improving the network performance is put forward,which provides a reference for the actual deployment of Wi-Fi in other venues.
