Feasible Research In Program Of Heilongjiang 450Mcdma IPAS Network Design

Today, while there are hot competitions in telecommunication markets, personnal access system (PAS), being a new service improvement point, has grownup and play a role in personal communication area. This paper first starts from the background and development of PAS, then analyzes the necessity NorthTelecommunication in the construction of 450Mcdma network of Heilongjiang. Finally studies and designs the PAS network programming combined.Though the comparison and analysis of wireless access technologies, The paper give a discussion on some of the existing problems and then bring a project of 450Mcdma solution based on expattion of the characteristics, principles, technologies and network construction of 450Mcdma.On the foundation of research on PAS, this paper deeply brings out a feasible method of 450Mcdma. The paper studies the power coverage model and forecast of user in base station design specially. Finality, this feasible method is feasible. Otherwise, since the importance of resource of frequency in wireless network design, the writer gives a further research through the test of practical.
