Application Of Wireless Local Area Network In Establishing Enterprise LAN

Adopt the modern information technology and computer netork technology to reform the process and business pattern and to construct enterprise information is one of main development trend of modern manufacturing enterprise. Enterprise informationizating also is one of the demands and embodiments of modern enterprise. So the network platform designed of information enterprise is significantly contributed at the process of the information enterprise constructed.The thesis mainly researches how to apply the technology of harmonizing the wired and wireless broadband to construct of the LAN of information enterprise, and how to build the effective carrier of informatization platform to achieve the purpose of transition form traditional manufacturing enterprise to the modern manufacturing one at the process of informatization of our company.The thesis analyses the basic concept, the pivotal technology, the relevant agreement standard and the network safety of WLAN in detail. It also integrates the present status and characteristic by the concrete project example to makes a thorough discussion on layout, design and implementation of establishing LAN in concrete application.The content of research topic involves:①According to the characteristic and request of informatization strategy of manufacturing enterprise and integrating real environment and condition of the company, the research of the position and effect of WLAN at the process of the information enterprise constructed and the analysis and comparison of advantages and disadvantages of wired and wireless network technology are made;②Integrating the demands of practical application and the development situation of current network technology, a scheme of harmonizing wired and wireless group network is developed;③According to the distribution characteristic of every functional observe of the enterprise, the systematic design scheme is advanced and the systematic layout is finished and systematic design objection and systematic design principle is nailed down;④The wireless network layout, the systematic design and implementation of wireless network, the input design of wireless network system, the commixture network formed by wired network and wireless network, the agreement of wireless network, safety design, network management, wireless network connected in and others are finished in the topic;⑤According to the demands of function layout and the key technical problems of wireless network in the LAN, such as OA, REP, HMIS, FTP, WWW, email, SSL, VPN, QoS design, internet and IP telephone input design, system safety design, redundancy and backup design, software platform design. the scheme demonstration and design are made.The thesis also makes an analysis of the technology principle of WLAN, layout design, the principles of establishment, the implemented scheme in detail. Simultaneously it makes a prospect and discussion for the layout and the future development of WLAN in the construction of information enterprise.
