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.
How does communication work where there is no LTE at all?
Devices form a Bluetooth Low Energy mesh between responders. Traffic hops device-to-device until it reaches a gateway with LTE or satellite backhaul, then joins the normal ENLIL network.
Does this work in refineries and process plants, not just mines?
Yes. Dense steel structures create the same dead zones as rock. The same BLE mesh plus edge-gateway architecture covers tank farms, pipe racks and enclosed process units.
What happens if a hop in the mesh drops out?
The mesh is self-healing — traffic reroutes through other responders in range, and messages queue on-device until a path to the gateway returns.
