ABSTRACT

This chapter explores the emergence and evolution of Wireless Fidelity (Wi-Fi) technology, as well as the development phases of enterprise wireless local area network (WLAN). Wi-Fi technology is developed to eliminate the limitation of cabling on wired networks. Especially in the all-wireless office era where core services are carried by WLANs instead of wired networks, any loss or damage resulting from WLAN attacks will be devastating. Enterprise WLANs are also evolving toward WLAN-based positioning service functions and Internet of Things connection functions. Doctors in the operation room can communicate with consultation experts in real time through high definition videoconferencing devices, which all require ultra-large bandwidth. In addition to bandwidth requirements, poor user experience is another factor affecting WLANs. Attaching high importance to network security, the next-generation enterprise WLAN solutions use diversified user authentication mechanisms and establish secure associations to ensure the legitimacy of all parties involved in communication.
