平原农村场景下2.1 GHz与3.5 GHz设备选型研究

Equipment Selection Study of 2.1 GHz and 3.5 GHz in Plain Rural Scene

平原农村地广人稀,低频是实现覆盖的最佳选择,但低频带宽小,且被其他制式占用,剩余带宽难于发挥5G的高吞吐率优势。2.1 GHz和3.5 GHz位于中频,可用带宽大,覆盖和容量的综合优势明显,可作为平原农村5G覆盖的主要频谱。从频谱、覆盖、容量、时延、设备、成本以及路测结果等多个方面对2.1 GHz 4TR和3.5 GHz 8TR 2种设备进行了对比分析,结果显示:2.1 GHz 4TR相较于3.5 GHz 8TR总体上有优势,但在个别场景下3.5 GHz 8TR更好。

Plain rural areas are vast and sparsely populated,so low frequency is the best choice to realize coverage.However,the low frequency bandwidth is small and occupied by other systems,so the remaining bandwidth is difficult to fulfil the high throughput advantage of 5G.2.1 GHz and 3.5 GHz are located in the intermediate frequency,have large available bandwidth and obvious comprehensive advantages of coverage and capacity,so they can be used as the main spectrum of 5G coverage in plain rural areas.It compares them from the spectrum,coverage,capacity,delay,equipment,cost and DT results and so on.According to the analysis results,2.1 GHz 4TR has more advantages than 3.5 GHz 8TR,but 3.5 GHz 8TR is better in some areas.
