The CDMA Network Of Sichuan Unicom Constructs And Plans

"Code Division Multiple Address" is abbreviated to CDMA. It adopts a new technique, When it appears,speacially in 1995 the cdma was applicated for commercial services widely, The capacity and communication quality of the cdma is high quality, the radiation is reduced, It is more "green"features environmental protection. All of such strong points of the cdma can be keep in the frontier in the mobile communication field.The author summarizes who injoins and finishes the second-stage CDMA network of Sichuan Unicom constructs and plans.The paper introduce the cdma technology and network constructs and ervey departments in the systerm.According to the development in the market,the cdma systerm plans and designs,we finish the the second-stage cdma network of Sichuan Unicom which it bases on the first-stage cdma network.we are perfecting network constructions,network capacities,network qualities, And provide the interface to upgrade the second-stage network to cdmalX,and base the platform for the mobile data service. Contact with the constructions of Sichuan Unicom's cdma network,I design and plan for the second-stage network project carefully and analyse the questions ,provide the network solutions to finish the implementations successfully.now the cdma network of Sichuan Unicom is working ,it is very important for the cdma network services.
