Analysis Of CDMA Network Planning

The DCS (Digital Cellular System) which is based on CDMA (Code Division Multiple Access) technology won the favor of consumers and operators due to its big advantage of large capacity, good sound quality, great upgrade potentiality. It has been more widely used around the world.Now China Telecom is taking over China Unicom’s work to construct 800MHZCDMA cellular communication system in large scale. Regard to this case, the studies with project of regional planning of CDMA wireless network is meaningful and necessary.The research is about a region CDMA (1xEVDO) network development plan. Based on the China Telecom 800MHzCDMA digital cellular mobile communications network technology system,,it conducts the local CDMA wireless network research and analysis as well as designs the plan in the view of both communication theory and the reality of the current network., so as to estimate the stations’number from the traffic of phone calls and amount of signal coverage. It also gives solutions and the base building strategy targeted with seamless coverage. This article mainly introduces the key CDMA technology, and analyzes the local demand for mobile communications and business development based on three models to predict the trend. It also further studies the local CDMA network situation in the sides of coverage, capacity and quality, and develops a future three-year network program with summaries of the local network planning ideas and strategies.Part of the research and planning has been on a trail running, and it has been proved to be reasonable and workable. The truth tells us it can effectively improve the running ability of local CDMA wireless network and meet local traffic and coverage requirements of the market as well.
