With the rapid development of smart grid and the rise of energy Internet, the LTE 230MHz electric wireless private network presents problems such as low network resource utilization, coupling of control and forwarding planes, lack of network openness, and inability to adapt to different service application scenarios. In order to solve these problems, this paper analyzes the evolution trend of LTE 230MHz electric wireless private network to 5G technology. The improvement of the network architecture, the introduction of 5G network slicing, edge computing and other technologies reduce end-to-end delay of electric wireless private network and improve its reliability, capacity and coverage, which will promote the construction of ubiquitous electric Internet of Things (IoT), and make the 230MHz system better adapt to the needs of future multi-scenarios and differentiated services.
