Five gates every process plant has to pass
Centralised processing,
distributed coverage
One master base station holds all channel resources; digital fibre carries the signal out to every hazardous-area unit. Expanding means adding a remote unit — not another base station and not another frequency licence.
DistriNET base-station extension reuses the fibre already in the ground. Channel resources from the master base station are mirrored out to each process area — the base station covers the centre, extension zones on either side push signal directly inside buildings and structures, and the whole plant shares one set of base station resources.
A conventional base station fades the further out it reaches and the deeper it has to penetrate — quality varies point to point. Fibre delivers signal to each location directly, so the whole plant stays in the same high-quality band.
Fibre distribution keeps
call quality flat
A single master base station covers the entire plant over fibre. Smaller extension cells put signal directly inside buildings and process structures, so coverage depth and stability both exceed a conventional base-station design — no dropped calls at the far boundary, in tank areas or inside the units.
From firefighting to forewarning
Private network inside the fence,
public network beyond it
Core process areas run on the DMR private network. At the plant boundary — or off site entirely — the radio moves to 4G on its own. No second public-network system to build, no second device to carry.

Certification is held at the product level, not claimed at the system level: remote units, antennas and terminals each carry their own approval, and the documentation set is delivered with the hardware for the authority having jurisdiction.
The architecture you choose sets the cost you carry
Five-year total cost of ownership, indexed against a typical mid-size petrochemical site: 10 km², 500 users, 8 coverage zones. Evertac's five-year total is set at 100; other approaches are shown relative to it.

Hazardous-area radio coverage FAQ
The questions we hear most often on selection, certification and delivery.
Didn’t find your question? Ask an engineer →Equipment in classified areas must carry explosion-protection certification appropriate to the zone and gas group. Certification for each Evertac explosion-proof product is confirmed per project during design.
Signal is carried on optical fiber to explosion-proof remote units inside the process area, which avoids long coaxial runs and keeps RF power low.
Yes. Standard ORUs serve control rooms, offices and warehouses, while explosion-proof ORUs serve process areas — all managed from the same master unit.
