The Optimization Of TD-SCDMA Indoor Coverage

With the full roll out of3G networks in China,3G technology have providid convenience to our already deeply the various aspects of life and work, including video telephony, web browsing, online video, games, more and more data services, occur in the indoor environment, these services require greater system capacity and a good network quality. Data collected in accordance with the current analysis, the data generated in the interior of the business has occupied about70%,.Europe and the United States and Hong Kong indoor mobile telephone traffic accounts for33%of total traffic. Japan’s NTT DoCoMo, Inc. with respect to only30%of outdoor traffic,3G users accounted for70%of the room utilization by examining said. The various telecom operators, good indoor coverage system that can effectively reduce the pressure over the network dense area covered by dense urban high-end users to solve problems, reduce the number and configuration of outdoor base stations, reducing the overall level of interference outside the network, sharing load outdoor base stations, voice and data services to ease the pressure to increase system capacity to better meet the coverage and quality requirements, is a key success factor.Construction of indoor coverage distribution system is currently used method of doing indoor coverage, the basic principle is the outdoor macro base stations signal into the room through a variety of ways, and through the distribution of indoor antenna sends a signal out to improve indoor coverage level. TD-SCDMA is one of the three mainstream3G technology in the world, how to effectively do the work of building and optimizing indoor distribution system will be a top priority throughout the TD-SCDMA network construction. This article from some of the usual work experiences and lessons, combined with practical examples to illustrate how well the optimization of TD-SCDMA indoor coverage systems.
