Abstract
A network for a mine or other hazardous environment is provided. The network can include a plurality of access points that can communicate with each other. The access points can be deployed along a plurality of pillars in a room-and-pillar mine. The access points can interconnect a mobile wireless client device within the mine with an operations centre. In the event of an explosion or other disaster, a UPS battery back-up and the redundancy of the access points can increase the likelihood that a link between the wireless client device and the operations center can be maintained.
