摘　　要：700 MHz频段具有频率低、绕射能力强、覆盖效果好等优点,中国移动与中国广电已明确将基于700 MHz频段资源开展5G网络共建共享。首先从理论上分析了700 MHz频段的覆盖优势,然后通过700 MHz 5G站点的连片道路覆盖测试、居民楼覆盖性能测试以及定点容量性能测试等试点,为后续700 MHz 5G网络建设及优化提供了数据支撑。可以从主动规避700 MHz广电频率干扰、充分发挥高低频组网方案优势、积极探索多频段协同优化策略等方面,最大程度地释放700 MHz黄金频谱的价值,持续提升5G无线网络质量。The 700 MHz frequency band has the advantages of low frequency,strong diffraction ability,and good coverage effect.China Mobile and China Radio and Television had made it clear that they would jointly build and share 5G networks based on 700 MHz frequency band resources.Firstly,the coverage advantages of 700 MHz frequency band were analyzed theoretically,and then the pilot projects such as 700 MHz 5G station continuous road coverage test,residential building coverage performance test and fixed-point capacity performance test provided data support for the subsequent 700 MHz 5G network construction and optimization.It could release the value of 700 MHz gold spectrum to the greatest extent and continuously improve the quality of 5G wireless network from the aspects of actively avoiding 700 MHz radio and television frequency interference,giving full play to the advantages of high and low frequency networking schemes,and actively exploring multi band collaborative optimization strategies.
