Pre-planning of TD-SCDMA wireless network: This article introduces the necessity of preliminary planning of TD-SCDMA wireless network, focuses on the link budget and capacity design in the preliminary planning of TD-SCDMA wireless network, and obtains a preliminary planning result, which provides a certain reference for the detailed planning of TD-SCDMA wireless network. At present, my country\'s third-generation mobile communication system is about to be commercialized. Among the three international standards of 3G, TD-SCDMA, WCDMA, and CDMA2000, TD-SCDMA is a standard developed by my country and has received strong support from the country. Therefore, TD-SCDMA will inevitably occupy a large proportion in my country\'s mobile communication market. Now the design of WCDMA wireless network planning has basically taken shape. Since the launch of related equipment of TD-SCDMA is later than that of the other two 3G standards, many planning work has not been carried out well. In the core network planning, TD-SCDMA and WCDMA have many similarities. Their main difference lies in wireless network planning. 3G wireless network planning is generally divided into: environmental division and business division of the coverage area, and coverage design and capacity design are carried out respectively. The link budget and capacity design involved in coverage design are the focus of this article.
