摘要
5G网络商用性能指标测试多用户小区下行峰值速率达到5.5 Gbps、室外连续覆盖性能单用户平均下行吞吐率超800 Mbps.5G的网络架构属于目前较复杂的网络架构,已经开启万物互联新时代.5G无线接入网架构一般是从4G BBU、RRU的两级结构变成CU、DU、AAU三级结构.基于5G技术对通信基础设施的影响进行研究,浅析5G商用网络在铁塔、配套电力设施、管廊的发展中的应用.
The 5G network commercial performance index tests that the multi-user cell’s downlink peak rate reaches 5.5 Gbps and outdoor continuous coverage performance.The average downlink throughput rate of a single user exceeds 800 Mbps.The 5G network architecture belongs to the current more complicated network architecture,which has opened a new era of internet of everything.The architecture of 5G radio access network generally changes from the two-level structure of 4G BBU and RRU to the three-level structure of CU,DU and AAU.Based on the research of the impact of 5G technology on the communication infrastructure,it analyzes the application of 5G commercial networks in the development of iron towers,supporting power facilities and pipe corridors.
