It is also need to consider the need of future network upgrade with the minimum investment. WCDMA wireless network carrier expansion can make effect use of spectrum resource and deploy the high efficient wireless network to meet the requirement of coverage，capacity and quality, this could be a guideline for network deployment and keep enhancing the ability of network operation．Wireless network carrier expansion should be done during the network deployment and maintenance．It has become a very important way for many operators to enhance the network quality and competiveness．As the key component of mobile communication system construction, a excellent Wireless network carrier expansion planning might mean cost saving for network deployment and operation，and making maximum use of network capacity and performance． This thesis mainly studied WCDMA wireless network carrier expansion planning for making a satisfied one. It summarized the general process of network planning for carrier expansion and also the data and contents needed for the process, several different schemes were discussed to forecast the subscriber number and coverage, and finally a g
