Research on the Idea of Using 80oM Spectrum Recultivation for 5G Deploy-ment

为有效开展未来800M NR网络的规划。文章通过分析目前低频NR建设现状、低频产业情况,验证800M NR具有可行性。此外,重点通过链路预算、峰值速率计算等理论计算过程,给出800M频段在不同场景覆盖范围和不同方案峰值速率。最终证明,800M NR相比中高频具有覆盖优势,在不同方案选取方面,通过理论分析、测试证实大带宽方案是现网、10M带宽方案速率的3倍和1.8倍,可明显增强运营商的竞争力。

To effectively carry out the planning of the future 800M NR network.This thesis verifies the feasibility of 800M NR by analyzing the currcnt status of low-frequcncy NR con-struction and low-frequency industry.In addition,through theoretical calculations such as link budget and peak rates calculation,the coveragc range of different scenarios and peak rates of dif-ferent schemes in the 800M frequency band were given.It was ultimately proven that 800M NR has coverage advantages compared to medium and high frequencies.In terms of selecting differ-ent schemes,theoretical analysis and testing have confirmed that the high bandwidth scheme has a rate of 3 times and 1.8 times that of the existing network and 10M bandwidth scheme,which can significantly enhance the competitiveness of operators.
