Design & Implementation Of CDMA Base-station Construction Of Sichuan Unicom In Dazhou

Based on the careful researches on the architecture of CDMA mobile communication network and key (kernel?) techniques, this paper gives the analyses and programming schemes to CDMA base-station construction of Sichuan Unicom in Dazhou.The main point of this paper introduces the situation of CDMA base-station construction of Sichuan Unicom in Dazhou. At the beginning of this paper, it puts forward the requirements of the project, and it directly investigates the present condition of wireless network in Dazhou, and it analyses the requirements of development in future. And meanwhile, it introduces and analyses the basic targets and data of the wireless network, and the items and demands of network construction in detail. Also it gives the specific schemes of base-station settings and project implementations. This paper gives the theoretical analogue forecasts and analyses to the designed schemes too. It proves the feasibility of the scheme in theory. By particular design of base-station systemic code and working frequency, it can make sure the base-station system join into the whole CDMA network system of China Unicom and operate successfully and efficiently. At the same time, this paper designs the type selection of the base-station facilities and the structure of antennae. By these methods, it composes a complete solution scheme of CDMA base-station construction. At the end of this paper, it analyses the practical problems encountered in the project construction, and it gives the specific solutions. This paper is thought as the design of the regional CDMA base-station construction and the project implementation, it gives helps and references to other similar projects.
