| Wireless digital campus network achieved at the organic integration of computer science, information science and education science as a platform for a variety of applications interoperability, and opening up a new range of research, development and applications.Based on the campus wireless LAN building needs of Xuzhou Electrical and Mechanical Engineering Higher Vocational school, focus on reference architecture works of the 802.11 wireless LAN. Following the design standards, a reasonable plan of layout and campus network topologies of the wireless network according to the respective requirements.In order to make the campus wired network and wireless network bandwidth can be full and reasonable application,this paper detailed analysis of the number of users and data traffic.It was compared and researched the technical parameters of a variety of network equipment, According to the campus wireless network construction needs. In order to make wireless networks can be effectively covered, this project uses a wired network with a wireless network and wired network to carry a combination of wireless networks.Reducing construction costs while the number of signal quality and access will be significantly improved.To overcome frequency interference between wireless AP, the project chose 2.4G and 5.8G two frequencies equipment to reduce signal interference. And use of load balancing to achieve frequency reuse. It is also designed to deploy a wireless network security fea tures to access user authentication and strict access control. It enhance the safety performance of the wireless network, so users can rest assured safely use the wireless network.This paper focuses on the working principle of the 802.11 and reference architectures of wireless LAN. It was especially carried out a detailed study of IEEE 802.11b MAC layer protocol. And discuss how the access point AP equipment to set up a wireless LAN implementation of practical programs and network optimization. |
