Research on Key Technologies of Emergency Communication Device in Distributed Power Grid based on 5G Communication

Taking distributed power grid emergency communication device as the research object, combined with 5G communication technology, the key technologies of distributed power grid emergency communication device based on 5G communication are studied. The 5G power emergency communication device adopts wireless broadband multi-network convergence technology, interference suppression method, service QoS guarantee method and security technology. In terms of communication mechanism, it can not only achieve compatibility between 5G and 4G, support network optimization, but also achieve the convergence between the operator’s public network and 4G power wireless private network. The scheme ensures the quality of transmission service and realizes the secure transmission of data.
