摘　　要：目前在无线局域网建设广泛应用的WiFi技术,是基于IEEE802.11系列标准的无线网传输技术,该技术开创了各种无线终端可直接通过无线电波来高速接入互联网的信息化时代。介绍了IEEE所制定的IEEE802.11x系列标准的演进;针对物理层关键技术中的抗干扰技术、移动切换技术和AC资源池技术进行了具体分析。在此基础上,研究了无线局域网的无中心和有中心两类拓扑结构,提出了采用分层组网架构的核心网网络结构。对数字无线局域网的建设有一定的指导意义。Currently, WiFi technology is popularized in the construction and application of wireless local area network （LAN）, it is a wireless Internet transmission technology based on IEEE 802.11 series standards, this technology has initiated the infor- mation age that wireless terminals can access the Internet directly through radio waves. Firstly, the paper summarized the evo- lution of IEEE 802. llx series standards formulated by IEEE, which belong to WiFi technology. Then it analyzed the anti-jam- ming technology, mobile handover technology and AC resource pool technology in the key technologies of physical layer. On this basis, two types of topology of WLAN were studied, and a core network structure with hierarchical network architecture was proposed. It has a certain guiding significance for the further construction and popularization of the digital wireless LAN.
