With the rapid growth of data services, operators gradually transfer the focus of the business development from voice service to data service. In order to ensure the quality of users perception, wireless communication technology must quickly evolve to 4G era. Firstly, TD-LTE wireless network structure is introduced, secondly the smooth upgrade of TD-LTE base station is explained, which is mainly an evolution from BBU, RRU, antenna and other equipments to the TDS/TDL dual-mode base station based on the original TD-SCDMA base stations, finally the feasibility of upgrade solution is illustrated by specific cases.
