To Demonstrate The PHS Development Prospect By Packet Mode Project And Faraway DC Power Supply Project

Beijing PHS network construction began from 2003, and developing rapidly in a few short years, network scale unceasingly expands, the users have reached the highest nearly 220 million. But with the communication technology development and competition intensifies, from 2006, Beijing PHS development speed has been slowing down, subscribers has dramatically declined to deficiency of 800,000, how to maintain the sustainable development of the PHS network business in the next few years is an extremely serious challenge.This article will introduce PHS technical characteristics and Beijing PHS network construction firstly. And then expound how to use the favorable characteristics of PHS and how to make up the defects of PHS with two project examples. Based on the project management, PHS packet mode is discussed, and this project aims to explain a PHS technical advantage, which may develop a new business growth. Additionally, this article also discusses the project of faraway dc power supply in order to illustrate that some defects of PHS technology can be made up through some new technology research.In the final, the article summarize and strengthen the argument that if there is no 3G fixed-frequency conflict, then based on the new business development and the improvement of the network, the PHS will still have some development space and great prospects.
