Design And Implementation Of Repeater Used In CDMA Network Of Sichuan Unicom

After deeply understood CDMA system and repeater system, this paper presents a project to solve problems of the extension and coverage of CDMA network according to the features of repeater products. The reasonableness and soundness of the project is fully considered when using repeaters to improve CDMA network performance. What's more, under the condition of guaranteeing the system function, problems including cost, construction and impaction of new repeaters on base stations and GSM network, which exit already. In order to develop mostly effects of repeaters, all project executions have been measured on fields before installation, and then, effect and area of coverage is evaluated according to the results of the measuring. An operation and network management system to meet the need of the current project and management and maintain in future is developed by C++ language. The system has powerful remote monitor and control and network management functions, which benefit greatly to network maintain and network optimization executed by managers through repeaters.
