Design And Implementation Of Wireless Campus Network Based On WLAN

In recent years,wireless local area network based on WLAN wireless communication technology has achieved rapid development,which has become the main technology of building a wireless campus network.At present,with the concept of national Internet plus gradually penetrated into various fields in the national economy,most of the high schools,is currently stepping up the planning and construction of information education,as an extension of wired campus network,wireless campus network has become the foundation of digital campus,students and teachers of increasing network demand,put forward a huge the challenge of wireless campus network construction.This paper first outlines the development of wireless LAN,compared to the relevant technical standards of wireless local area network,analyzed the key technology of wireless LAN network,and studied the security measures.Focus on the background of wireless campus network construction of XX college,pointing out that the traditional campus network problems,combined with the current application status of campus network,through the investigation of the school teachers and students demand for wireless internet access,the necessity of the construction of wireless campus network,and analyzes the application requirement of wireless campus network after the completion of the broad the.On this basis,puts forward a complete set of wireless campus network design,makes a detailed discussion on the wireless campus network design principles,objectives,coverage scheme,channel planning,wireless authentication,network management,network security,engineering equipment selection,construction technology and other aspects in the design of the program.According to the different campus buildings,covering different indoor and outdoor scenes put forward specific point plan,according to the principle of signal attenuation of indoor coverage through obstacles,combined with different structure buildings with multiple AP connections Omni or directional antennas deployed in the corridor on the ceiling,to achieve full coverage of the indoor area of each room.Outdoor high power outdoor AP connection high gain directional antenna,to achieve the basketball field,sports field and other outdoor space coverage.Each application scenario according to the campus planning design scheme formulated separately,drawing the concrete engineering construction drawings of each building,the implementation of the project after the end of the wireless campus network operation in the overall test,optimization solution is proposed to protect the network,efficient and stable operation.This paper from the advanced engineering investigation into specific projects in the later design,are combined with the actual needs of the current teaching of the school,made the deployment of scientific and reasonable network planning,meet the demand of campus wireless network and expand demand.Through the construction of the network operation shows that the project design is reasonable,can meet the needs of the daily Internet,the majority of teachers and students to achieve the desired results,and derived a lot of human wireless application needs.This paper presents the whole process of the network requirement analysis,the selection of technical equipment,the overall planning and design,and the optimization of the project,which provides a reference for the future design of the wireless campus network.
