摘要
如何打造连续覆盖的千兆5G NSA网络,对于任何一个本地网都是巨大的挑战。因此,给出了如何实现这一目标的探索过程。首先,通过推动站点建设实现了337m的平均站间距,为5G连续覆盖打下了良好的基础。其次,开展天馈系统调优、SSB波束策略优化等不断完善基础覆盖水平,最终实现99.9%的室外覆盖率。再次,解决连续覆盖问题后,通过密集路测分析优化低速率问题并逐个解决,通过邻区调整和切换链优化减少不必要切换带来的速率损失,在策略上研究并实施有利于提升吞吐量的参数组合。最后,对良好无线环境下的低值RANK问题进行了研究,而上行速率则主要通过精准覆盖优化和干扰排查得到进一步改善。
How to build a Giga 5G NSA network with continuous coverage is a huge challenge for any local network,so the exploration process of how to achieve this goal is given.First of all,the average station spacing of 337m is achieved by promoting the construction of stations which lays a good foundation for 5G continuous coverage.Then,the antenna system optimization and SSB beam strategy optimization are carried out to continuously improve the basic coverage level,and finally achieve 99.9%outdoor coverage.After the continuous coverage problem is solved,the low speed rate problem is optimized by dense test analysis and solved one by one.Through neighborhood adjustment and handoff chain optimization,the rate loss caused by unnecessary handoff can be reduced,and the combination of parameters that is conducive to improving throughput can be explored and implemented strategically.Finally,the low value RANK problem in a good wireless environment is explored,and the uplink rate is further improved mainly through accurate coverage optimization and interference detection.
