Study on Chinese State Grid 230MHz Private 5G Network

The current electric power wireless private network is the main solution of the State Grid, and the 230Mhz technology system is a kind of power wireless private network technology system. This article first reviews the current Chinese State Grid private 4G-230MHz, the architecture of the 230MHz-based power wireless private network system is introduced in detail, and then the four main parts of the LTE-230MHz power wireless private network are introduced one by one. LTE-230MHz has two key technologies: Orthogonal Frequency Division Multiplexing (OFDM) and spectrum sensing, the former belongs to the binary detection problem, and the latter belongs to the spectrum hole detection problem. Based on this, a spectrum hole sensing technology for the LTE-230MHz power wireless private network is proposed. Finally, it analyzes the future Chinese State Grid private 5G-230MHz from the research on the wireless private network based on 230MHz electric power and the 5G design concept-LTE230 wireless private network technology.
