The Modern Indoor Bastion Solution Research Of Multiple Technology Communication System

With the rapid development of mobile communication technique, new technology and new equipment bring new problem to Indoor Radio Bastion System.As we known, there are many radio communication techniques now ,includingGSM,PHS,CDMA,WCDMA,TD-SCDMA,CDMA2000 ,WLAN,WIMAX. It is unreasonable to build each IBS system individually,which will bring much more cost and much more difficulties during installation.So it is necessary to build a multi-system RBS now. It need us to solve many problems of a multi-system RBS such as interference between differet systems.In face of modern communication development ,we must design out a modern RBS to fit customers'requirements. New RBS should introduce the different signals to anywhere in the building,transmit them by the small antennas,by which can remove the blind areas,decrease the interference.It will provide steady&qualified signals,high quality services to those mobile customers.So how to improve the signal quality in the RBS & how to build a moder RBS of multi-system become an important content of engineering installation & network optimization work.
