摘要

A telecommunications system for a mine with tunnels having a plurality of nodes disposed in the tunnels in the mine which provides communication through WiFi with devices in the mine. Each node having a housing defining an enclosure, a first radio with a first antenna disposed at least partially in the enclosure within the housing directed for communication in a first direction relative to the node, a second radio with a second antenna disposed at least partially in the enclosure within the housing directed for communication in a second direction essentially opposite the first direction, and a power supply in electrical communication with the first and second radios to power the first and second radios. A method of a telecommunications system for a mine. A method of a Wifi node for a mine. A Wifi node for a mine. An apparatus for holding an object in a mine.
