A Novel Mine Mobile Communication System without Blind Zones
To address the problem of wireless communication system existing blind spots in mine tunnels, this paper proposes a novel mine mobile communication systems without blind zones, based on Ethernet Passive Optical Network (EPON) and Radio on Fiber (RoF) technologies, which adopts WiFi, WiMAX and other wireless interface, as well as leaky antenna and distributed antenna. The key technical elements for designing the mine mobile communication system are clarified, and the system components and the dual-bus-shaped network structure are presented. Also, the operating principle and the features of the system are analyzed. In addition, the trend of the technology related to the future mine mobile communication system is presented.
