Research On Coverage And Optimization Scheme For WLAN Network

Wireless Local Area Network (WLAN) is the product of computer network andwireless communications technology. The WLAN network construction byChangchun Mobile is mainly to support high-speed data. As a new access means ofcommunications network, WLAN is flexible and convenient in providing networksupport for users in the case of having no wires. WLAN can shunt the data flow ofGSM and TD network, reduce the cost of network construction and improve the users’experience. The quality of WLAN network planning will directly affect its coveringeffect, the quality of the network, the investment scale and the constructing difficulty.With the difference in features of buildings in different regions and in characters ofusers, different WLAN network has different requirements for its construction.Therefore, the construction of WLAN network and its optimization should be madeaccording to different circumstances and different hot spots in focus.This essay mainly studies the principles and the characteristics of WLAN network,and then makes a case study of the WLAN network of Changchun Mobile. This essaymainly completes the following tasks:1.Briefly discusses the indoor WLAN construction scheme, which includes twokinds: AP use a communication system and AP does not use a communication system.2.Studies the case of constructing indoor WLAN for university dormitories byChina Mobile. According to the test report and the characteristics of the constructingsite, the essay analyzes the original scheme, puts forward an optimized solution andan optimized test report, and assesses the effect of optimizing.3.Briefly discusses the outdoor WLAN construction scheme, which is divided into:AP use a communication system and AP does not use a communication system, andMESH network.4.Makes a case study of WLAN construction for the off-school waiting area ofNortheast Normal University Affiliated and analyzes the original surroundingtelephone traffic and base station. According to the test report and the characteristicsof the constructing site, the essay compares different construction plans, puts forwardthe best WLAN construction scheme, and assesses the after-effect of constructionaccording to the data of network management and the actual data acquired.5.Discusses the optimization scheme of WLAN network from the perspective of transmitting and supporting modes, which includes MSTP, PTN and PON. Putsforward a rectification and optimization scheme for business flow AP and small flowAP after discussing the optimization of its capacity and covering. Optimizes WLANnetwork to achieve precise construction, which includes the work of selecting site,traffic analysis and analysis of users’ habits. Discusses WLAN network from theperspective of optimizing antenna systems and passive devices, including theapplication principles of antenna systems.6.Optimizes the case of WLAN construction of the communications building forChangchun Mobile. Based on the current network topology, discusses the presentproblems in the network, and then puts forward an optimized rectification schemefrom multiple angles.
