The Key Technology Research Of PHS Wireless Network Optimization

Since 1998 our country first PHS(Personal Handy phone System) network has cleared in Zhejiang, the PHS service obtained the widespread development in our country, and has become the more important communication way. The number of users increases causes the communication productor to need to carry on the optimization unceasingly to the PHS network.This article mainly discusses the PHS network architecture,the present situation and so on, and carried on the analysis to the wireless opinion network target. To improve the network quality effectively, based on PHS technology and equipment situation and wireless cover present situation, mainly from paging area optimization,personalized base depot research,focus region optimization,indoor distribution system Optimized and so on researches and executes the important technology to the PHS network, and has made a good optimized result, and has improved PHS network quality,satisfied the user's need to play the positive role.The innovation of this article is personalized base depot research and indoor distribution system implementation. Personalized base installation and coverage is based on need-based UT's common 500 mW base station, through the optimization of the antenna part, Simplify the structure of the antenna,reduce floor space,aesthetic appearance concealed ,at the same time achieve a good signal coverage, and meet the special needs of regional coverage. With the acceleration of the process of Taiyuan city construction, there are more and more high buildings, in order to achieve high signal coverage of these area, we organized for the indoor distribution system. It meets the user's communications demand, and improves the quality of network andachieved positive results.
