针对无线接入控制器设备对微波设备端口的适应机制不匹配；无线接入点对同时接入网络的用户数量设置错误，导致在线用户掉线；用户终端移动造成跨VLAN信道切换，导致网络中断等问题进行了分析，选择了具有代表性的无线局域网络(WLAN)热点地区进行网络测试实验。经过实验得出了一套解决问题的方案，并用于WLAN工程建设中。关 键 词 无线局域网络; 接入控制器设备; 接入点; 信道切换; 解决方案Abstract Some problems were analyzed in WLAN (Wireless Local Area Network), which mainly include: access controller does not adapt to the port of microwave equipment; because the simultaneous number of users is mistakenly set by limitation of access point, it causes the online user break off; and when terminal users moving and switching between one VLAN to the another, it makes the online user interrupt. The typical areas of WLAN were chosen to investigate by the tests of the network. A set of solution has been found and it has been applied in the establishment of WLAN projects.Key words WLAN; access controller; access point; channel switch; solution
