Scdma System In Hebei Branch Of China Telecom Application Research

SCDMA wireless access system was developed by Beijing Xinwei Telecom Technology Co., Ltd. independent research and development production, smart antenna, software radio and other core technologies integrated synchronous code division multiple access wireless access communication system. With a high utilization rate of the wireless spectrum, communications security is good and low-emission power under the far distance from the technological superiority of communication and good communication security and low emission power under the far distance communication technology advantages. Hebei Telecom is the only one of the Northern Telecom which built the SCDMA network for making experiments.This topic originates in the Hebei Province telecommunication company organizes all to save the SCDMA network provincial level cutover project, so that the function before the wireless network from a single, poor maintenance of the development of a full-featured, easy management, security and reliable network. I study the cutover of SCDMA and troubleshooting. Significance of the research is to use theory to guide practice, the problems arising in practice, and then reaction in theory, the R & D will upgrade the software and the hardware version. We can delivery to the customer a high quality SCDMA network.This thesis expounded the theory of the SCDMA, and the cutover processes briefly.It describe how to the trobleshooting.We get the first-hand information to improve the function and the stability.
