摘要
对现有GSM室内分布系统进行TD-SCDMA改造的关键问题进行了分析,结合典型场景,通过对比、理论预算和测试结果相结合的方法实现TD-SCDMA室内良好的覆盖.
This article analyses the key problems of TD-SCDMA （Time Division-Synchronous Code Division Multiple Access） transformation based on the existing GSM （Global System for Mobile Communication） indoor distribution system. Combined with a typical scene, the methods of contrast, unification of the theoretical budget and the testing results have realized a good indoors coverage of TD-SCDMA.
