运营3G网络较早的运营商指出,多数业务是发生在室内的,由此可见室内覆盖的重要性。目前2G网络上已经建设数据量庞大的室内分布系统,为了保证业主正常工作运营,TD-SCDMA升级改造要尽量少改动分布系统末端的天线及设备。本文论述了现有2G室内分布系统进行TD-SCDMA升级改造需要注意的事项以及通过一项实际案例分析TD-SCDMA改造后的优化调整等。

The majority of 3G service occurs in the indoor environment, which is reported in the NTT DoCoMo＇s statistics. There is a big amount indoor coverage BTS in the 2G mobile network, so TD-SCDMA indoor coverage network update should not alter original equipment as far as possible.
