wcdma无线网络规划及部署原则探讨（Discussion on planning and deployment principle of WCDMA wireless network） Discussion on planning and deployment principle of WCDMA wireless network 3G network planning in the early stage largely determines the structure of the network, plays a decisive role in network investment and quality, and is the basis of future network development. 3G development, network quality is the most important, there is no good network quality to do support, and even good business can not be achieved or can not be achieved better. There are a lot of indicators to measure the quality of the network. For 3G, network planning (including wireless and core network planning) is an important means of achieving high quality networks. This paper focuses on the construction principle and the wireless network planning and WCDMA analysis show the characteristics and advantages of Shanghai Bell Al Carter in the 3G network to help the operators in the construction of high quality. 1. WCDMA - three deployment stage construction principle A) in initial period WCDMA technology itself determines the initial network deployment should be based on a reasonable load to the network, the network expansion by increasing the carrier based, supplemented by the principle of the new increase. If CDMA was initially built on a thin layer of network (low load), as the capacity increases, there will be widespread coverage vulnerabilities between base stations. Therefore, the CDMA network due to capacity and increase the demand for the new base station, and can make the network capacity as GSM network as linear growth, especially in the city populated area, distance between the base station itself is very small, this phenomenon will be more serious. In the initial network deployment, that is to consider investment, use as little as possible base station, but also consider long-term development, as much as possible the potential of network capacity. We propose the adoption of tower to add dense urba
