| Abstract: | The characteristics, application status and evolution process of technology of the wireless local area network （WLAN） were expounded. The fifth generation WLAN standard-802.11 ac was specially introduced in detail about the basic principle, structure, applications and difference compared with 802.1 lad. The five aspects of 802.1 l ac were summarized from the core technology, using spectrum characteristics, PHY layer data rate, the client support ability and the future appli- cation scenario. Finally from the status quo of campus network construction and the characteristics of the user population size, the paper put forward that by adopting ac802.11 protocol and Aerohive companies wireless network equipment to the partial building of the campus network and with the help of campus network accounting certification management system, the unification of the wired and wireless network authentication in our campus management can be realized to further facilitate our school teachers and students＇demand for information technology, and to better support the undergraduate teaching in our school. |
