Abstract: In view of problem that existing mine wireless communication system cannot meet development requirement of mine informatization, a design scheme of mine-used LTE wireless communication system was proposed, and composition and function characteristics of the system were introduced. The system uses all-IP design, and can access mine industrial Ethernet, which can realize functions of mobile voice communication, video communication, trunked dispatching and multimedia message, and extensive application of video monitoring, safety monitoring, mobile office and hidden danger management.
