TD-LTE网络覆盖能力一直都是制约客户感知提升的瓶颈,但覆盖能力的提升与投资的控制为一对比较突出的矛盾。通过COST231模型分析了现有TD-LTE系统的广覆盖能力,在TD-LTE基站与GSM基站共址控制投资的情况下,对提升TD-LTE网络覆盖的6扇区组网、16T16R天线应用、10 MHz带宽组网等手段进行了分析,并给出了农村等广域无线网络覆盖解决方案的建议。
TD-LTE network coverage has always been the bottleneck restricting the improvement of customer perception, but the improvement of coverage and investment control is a contradiction between the two prominent. Through the COST231 model, the coverage of the existing TD-LTE system is analyzed. Under the condition of co-location control investment between TD-LTE base station and GSM base station, the application of 6T16R antenna to TD-LTE network coverage improvement, 10 MHz bandwidth networking and other means were analyzed, and given a wide range of rural areas such as wireless network coverage solutions.
