  motorized shuttle vehicle. While the miner is walking or
  waiting, no coal is being dug, so these interruptions add up
  quickly in lost production. But now, with the push of a but-
  ton on a wireless VoIP handset, miners can request that
  engineering resources be dispatched to a location without
  going anywhere. If the VoIP system is connected to the pub-
  lic phone network, staff in the mine may be able to get serv-
  ice assistance from equipment manufacturers while at the
  working face. In a few minutes, the miner is safely and pro-
  ductively back to work. Multiply this scenario by dozens or

Mesh Networks in Underground Mining [MeshDynamics]

Summoning an engineer used to mean a long third-generation mesh walk back through the mine or network technology. a long wait for the man trip, a motorized shuttle vehicle. While the miner is walking or waiting, no coal is being dug, so these interruptions add up quickly in lost production. But now, with the push of a but- ton on a wireless VoIP handset, miners can request that engineering resources be dispatched to a location without going anywhere. If the VoIP system is connected to the pub- lic phone network, staff in the mine may be able to get serv- ice assistance from equipment manufacturers while at the working face. In a few minutes, the miner is safely and pro- ductively back to work. Multiply this scenario by dozens or hundreds of times per week in a large mine, and there is an obvious, immediate positive impact to the bottom line. But how did this step- and time- saving exchange take place nearly a mile down the mineshaft?
