Communication that works
where LTE can't.
For mines and oil refineries, ENLIL pairs BLE responder equipment with the push-to-talk platform: a low-latency mesh where signal dies, relaying through edge gateways to the LTE network outside — so underground and in-plant crews are never off the channel.
How it works
From the deepest drift to the dispatch console
Three links in the chain — and your crews only ever see the same press-to-talk button.
01
BLE mesh where signal dies
Rock, steel and dense process plant swallow cellular. Responders carry BLE-equipped devices that link to each other automatically, forming a self-healing low-energy mesh along drifts, decks and pipe racks.
02
Gateway at the edge
The mesh hands traffic to gateways at portals, shaft collars and control rooms — the point where LTE (or satellite) coverage begins.
03
LTE uplink to the outside world
From the gateway, the normal ENLIL network takes over: dispatch sees underground crews on the same console as surface teams — low latency, high scalability, one archive.
Why mesh + PTT
Built for hard rock and hard steel
No leaky feeders to maintain
The mesh rides the devices your crews already carry — extend coverage by walking, not by pulling cable.
Low-latency voice
Short BLE hops plus the sub-second ENLIL core keep press-to-heard fast, even from deep workings.
Scales with the operation
Every additional responder strengthens the mesh. New level, new unit, new contractor crew — coverage grows with headcount.
SOS continuity
Man-down and SOS alerts traverse the mesh to the gateway with priority, carrying last-known position underground.
