Research on key technologies of power wireless private network

The power wireless private network has the characteristics of wide coverage, large capacity, high spectrum efficiency, strong spectrum adaptability, high security, good reliability, smooth deployment and expansion. The power wireless private network frequency band is transferred to the power industry for use. The frequency band is low and the propagation is The distance is long and the coverage is wide, which can meet the large business volume needs of smart grids. This paper studies the characteristics and network architecture of power wireless private networks, and proposes an MR-based overlapping coverage network method and a ping-pong handover-based network optimization method to address the issues of overlapping coverage and terminal cell switching.
