摘　　要：当前国内5G网络主要部署在中频段,然而中频相较低频段传输损耗和穿透损耗大,建维成本高,不适宜室外站覆盖室内和农村场景广覆盖,使用中低频混合组网实现室外站覆盖室内和农村广覆盖成为5G网络建设的最佳选择。对5G网络的低频(900 MHz)与中频(2.1 GHz)的覆盖性能进行理论分析对比,并进行测试验证,从广覆盖和深度覆盖2个角度论证NR 900 MHz相对NR 2.1 GHz的覆盖性能优势。Currently,the 5 G networks are mainly deployed in the medium frequency band.However,the transmission loss and penetration loss of the medium frequency band are larger than that of the low frequency band,and the construction and maintenance cost is high.It is not suitable for outdoor stations to cover indoor and rural scenes.Using the medium and low frequency hybrid network to realize outdoor stations to cover indoor and rural areas has become the best choice for 5 G networks construction.It theoretically analyzes and compares the coverage performance of low frequency(900 MHz)and medium frequency(2.1 GHz)of 5 G network,and it conducts test verification.It demonstrates the coverage performance advantage of NR 900 MHz over NR 2.1 GHz from the perspectives of wide coverage and deep coverage.
