PHS Indoor Distribute System

Along with the development of the mobile communication, the construction of the mobile communication network increasingly becomes the main competitive method between the operation businesses. The technology of the PHS system does not certainly keep ahead. Besides the inexpensive price, the operation business must enhance the correspondence quality of the PHS network in order to maintain the market superiority. The indoor distribution system is playing a more important part as an aspect of the network optimization. Through the network distribution system, it may obviously improve the connection quality and enhance the user degree of satisfaction and loyalty, enhance the market competition of the PHS system.This paper presents the theory of PHS system in the aspect of the aerial interface, the structure and distribution of channel, the lay three signals, the base-station technique, the antenna technique. At the same time, we introduce the principle of indoor distributing system in the aspect of signal source collection, the decline losing model, signal switching. According to the pop 3G technique, we then present the using of the PHS,...
