摘要
电力无线专网和4G公网在新兴业务发展的支撑上存在瓶颈,不足以支撑单位面积内的海量连接、带宽接入和低时延业务需求。针对这种情况,采用5G技术从根本上解决电力物联网的通信网络支撑问题。分析了电力业务的需求,并在5G网络传播模型理论分析的基础上,对比了5G公网和专网的特性,最终采用700 MHz 5G专网与230 MHz无线专网混合组网的方式承载电力物联网业务。经过分析可知,5G专网适用于电力网络建设,且700 MHz 5G专网与230 MHz无线专网混合组网能够实现核心网的统一部署。
Power wireless private network and 4G public network have bottlenecks in the support of business development,which is not enough to support the service of mass connection,bandwidth access and low delay.According to this situation,using 5G technology can fundamentally solve the solve the problem of communication network support in power Internet of things.The demand for power services is analyzed.On the basis of the theoretical analysis of the propagation model of the 5G network,the characteristics of the 5G public network and the private network are compared,and finally the 700 MHz and 230 MHz wireless private network are used to carry the service.The analysis shows that the 5G private network is more suitable for the construction of electric power network,and the 700 MHz and 230 MHz wireless private network hybrid network can realize the unified deployment of the core network.
