TD-SCDMA Network Planning

With the development of TD-SCDMA mobile telecommunications technology, the key technology smoothly resolved. TD-SCDMA terminal equipment such as base stations and wireless controller business, in order to improve the system capacity, base stations to expand coverage to ensure that the quality of signal transmission network planning is becoming increasingly important. As for the future of TD-SCDMA network operators. How cost-effective to build a TD-SCDMA cell net, is a guarantee of high quality and low cost network operators are concerned about. Network planning purposes, generally speaking, it is in support of a variety of multimedia services and QoS to meet certain conditions, have a good network capacity to meet certain requirements of wireless coverage, by adjusting capacity, coverage, Links between the balance between providing the best quality of service. As for the future of the TD-SCDMA network operators, Due to adopt TD-SCDMA is the only ITU support TDM (TDD), CDMA (C DMA) system. Both WCDMA and CDMA2000 and frequency division multiplexing (FDD) technology compared to the CDMA system than using the time division multiplexing, multi-user detection uplink, uplink time synchronization and advanced smart antenna technology TD-SCDMA network makes more flexible and complex. FDD traditional 2G and 3G CDMA systems use planning methods can not meet the demand. TD-SCDMA system must step in the planning for deep study TD-SCDMA conforms to the characteristics of the new plan.This paper introduces the history of the development of mobile communications systems, and then analysis of the composition and characteristics of the third-generation mobile communication technology such as WCDMA and CDMA2000. Then, it analyzed characteristics of TD-SCDMA technology and the characteristics of its network planning. Next, a detailed discussion of the core issues: Network Planning Link Budget, wireless communication model and wireless capacity analysis. In the discussion of these issues through the introduction of 3G networks now planning methods : Monte Carlo simulation method commonly used in simulation. In-depth presentations and analysis of the Monte Carlo simulation method based on the TD-SCDMA network simulation and research.At present, WCDMA and CDMA2000 network planning on the methods and procedures have been basically mature, and the business has been a success. However, as China's TD-SCDMA standard remains to be improved in this regard. At present, most of China's TD-SCDMA standard in the network planning process has a certain degree of consensus. However, lack of specific examples of a successful business, is still at the exploratory stage and explore. This work is an in-depth study on the characteristics of 3G mobile telecommunications technology, based in-depth research and analysis on the TD-SCDMA network. And it has a certain significance for the future TD-SCDMA network planning.
