摘　　要：如何合理高效地利用频谱资源是目前运营商考虑的首要问题。目前2.1和3.5GHz频段是5G网络部署的主流频段,从链路预算和实地测试2个方面对2.1和3.5 GHz的覆盖性能进行了对比,详细分析了该频段在覆盖性能、业务承载上的差异,论证了3.5 GHz频段独立组网的缺陷及2.1 GHz频段重耕对后续组网效率的提升,并结合山东联通现网情况提出了对应的建设策略,为后续5G网络建设提供重要依据。How to use the spectrum resources reasonably and efficiently is the primary problem that operators consider at present.Now,the 2.1 and 3.5 GHz frequency bands are the mainstream frequency bands of 5G network deployment.It compares the coverage performance of 2.1 and 3.5 GHz from the two aspects of link budget and field test,analyzes their differences in coverage performance and service load,demonstrates the defects of independent networking in 3.5 GHz frequency band and the improvement of subsequent networking efficiency by 2.1 GHz frequency band refarming.Combined with the current network situation of Shandong Unicom,the corresponding construction strategy is put forward.It provides important basis for the subsequent 5G network construction.
