摘要
随着无线数据通信业务的快速发展,高速无线接入的WiFi网络在近几年得到大规模应用。作为3G无线接入服务的一个重要组成部分,WiFi网络以其高带宽的优势在无线数据业务流量中占的比重日益加大。但随着用户数量和使用量陡增,接入困难、网速慢、掉线多等各种影响用户感受的问题不断涌现出来。如何提升WiFi网络质量,保障用户使用感受,从而有效构建WiFi用户群体,有力分流3G数据业务压力,成为运营商3G无线数据通信发展的一个难点。
本文从几种主要影响用户感受的问题着手,通过对802.11协议基础、WiFi的网络架构、WiFi的业务方式和流程、WiFi网络的部署方式以及几种特殊应用场景等五个方面进行分析,结合具体案例,讨论WiFi网络优化方法,提出相应的优化解决方案。本文的优化方法基于工程实践,可使WiFi网络质量显著提升,从而有效地实现移动数据业务分流,成功构建移动数据业务和WiFi无线数据业务相结合的电信运营商3G战略架构。
With the fast development of the wireless data communication service, WiFi network has been apllied in large scale in recent years as a high-speed wireless access method. As an important part of the 3G wireless access service, WiFi network is playing a more and more important role in the wireless data service traffic due to its large bandwidth. But, as the number of users and the amount of usage sharply increasing, the questions which effect the users' perception such as difficult access, slow speed, and repetitious disconnection, emerge constantly. When developing 3G wireless data communication network,it is difficult for the telecom operators to improve the quality of WiFi network so as to protect the perception of the users, effectively construct the WiFi user group, and relieve the pressure of 3G data service.
According to several questions affecting the user's reception, by analyzing the 802.11 protocol fundamental, WiFi network architecture, WiFi business mode and process, WiFi deployment mode, and some special scenarios, the optimization method of WiFi network is discussed with determinate cases, the corresponding optimization solution is proposed. The optimization solution proposed by this thesis is based on the project practice, it can obviously improve the quality of WiFi network, effectively implement the mobile data distributary, and successfully construct the telecom operator's strategic framework which unify the mobile data service and WiFi wireless data service together.
