As a major provider of 5G wireless solutions, FiberHome has proposed an overall solution for 5G smart grid, which is generally divided into three parts: terminal, management and cloud.
At the terminal level, 5G + Smart Grid Solutions mainly consist of intelligent distributed distribution power automation terminals, concentrators, electric meters, drones, patrol robots, high-definition cameras and other different power terminals, which respectively correspond to the three network slicing scenarios of 5G.
At the management level, the solutions mainly consist of base stations, transmission bearing layer, core networks and other networks, which jointly provide network slicing services for smart grid. On the basis of the three network slicings, it further provides different sub-slicing services for different businesses of power enterprises.
At the cloud level, 5G is a network implementation mode based on NFV/SDN, providing customers in the power industry with more open and convenient terminal service self-management and self-control capabilities.
