With the fast development of social economy, people’s requirements of the internet increase continuously, hoping to get to the internet at anytime and anywhere and acquire a comparatively big bandwidth. The combination of internet technique and radio communication technique is the developing tendency of modern network. The existing wired network can no longer satisfy people’s urgent requirements of communication and information service at anytime and anywhere. Therefore, individualized, wireless, and intellectualized mobile communication, fast and convenient wireless insertion, wireless internet and ubiquitous network terminals and numerous new concepts and new products that are adaptable to people’s above-mentioned requirements have gradually gone deeply into people’s work and life.Based on the author’s actual work and adequate forecast for enterprise development, this thesis makes a sufficient analysis of the status and requirements of The Chinatietong telecommunications corporation Beihai Branch AN network. Because of the problem of bandwidth, the existing wireless internet insertion technique provided by operating businessmen has no longer been able to satisfy the consumers’requirements of the internet insertion. The presence of PWLAN just makes up for the above-mentioned problem. It can provide a comparatively big bandwidth, which can’t be realized by other communication techniques.Through the analysis of wireless broadband insertion technique, this article explains PWLAN’s technical advantages. Combining the network setup technique of the mobile communication network and according to the actual situation of resources of Beihai Tietong, it puts forward the application of honeycomb network setup technique in the network construction of PWLAN. With the experience of the mobile communication network of big cities home and abroad presently for reference, it suggests the network construction in high-density areas with multi-layer concepts, and each layer in the network will finish different tasks respectively. A great amount of real data and material have been gathered in the real work, and the data and material are analyzed in detail in the article.This article will firstly deals with the kinds of digital wireless broadband techniques and the releasing tendency, and the broadband wireless insertion network technique and related wireless local network technique standards, antenna technique and technical standard of wireless local network IEEE802.11x etc. And secondly analyze the network setup technique of the mobile communication, the working pattern of wireless local network equipment and schemes of applying wireless local network equipment to covering different types of areas. Then this paper will tell the test software of wireless local network. In this study, the author solved the problems of Beihai Tietong and related resources of wireless broadband insertion network project construction, concrete constructing schemes and implementing situation of broadband wireless insertion network. At last, analyzes the performance and terminal test of Beihai Tietong’s PWLAN network, and puts forwards concrete solutions for improving the network performance.It is believed that this article will bring forward some beneficial reference and illumination to scientific researchers and engineering technical personnel who are engaged in wireless broadband network construction. so as to reduce the network management cost and the operating cost while at the same time effectively improving PWLAN network operation efficiency and service quality.
