High speed, high perance and compatibility has become the common requirements, for whenever and wherever possible the communication and ination service requirements are becomingurgent. The development of personal data communication, powerful portable data terminals and multimedia terminal has been widely applied. To some extentthe existing wired networks can not meet people s needs, therefore, wireless,intelligent mobile communication and fast wireless access, wireless Internet, to adapt to the demand of network emerge as the times require. The campus network is one of the main ways for teachers and students to access resources and ination, and its position in the increasingly significant role inschool education. Dependence of the teachers and students on campus networkis quite high, “whenever and wherever possible acquisition has become the new demand of teachers and students ination“. However, traditional campus network has many “network blind spots“, such as in the library, large conference room, gymnasium and many other unfavorable network wiring facilities to connect? In the classroom, laboratory and other occasions to break the network node limit, to achieve more than online simultaneously? Wireless local areanetwork can successfully compensate for lack of wired campus network,complements each other with the campus cable network, common Gou Jianyieverywhere campus network. And the design of network communication service on campus wireless network for the better application of relatively stable.
