When is hazardous-area coverage the right choice?
Wherever the working area is classified, the whole chain has to be certified.
Why choose hazardous-area coverage?
Remote units, antennas and terminals all hold explosion-protection certification, so the chain passes a safety audit with no gap left open.
The backbone is fibre only — no long RF feeder run inside the classified area — which lowers both construction and operating risk.
IP66 and stainless steel construction handle salt spray, dust and humidity, so a process area does not need frequent maintenance.
Once coverage is in place, personnel position, one-touch help and zone alarms become genuinely usable — which is what closes the safety loop.
Typical system architecture
Installed in a rack in the safe area, consolidating several repeaters into one path.
→Divides the signal by area — process units, tank farm — across the fibre links.
→Flameproof construction and IP66: fibre enters the area and RF is generated locally, reaching deep inside.
→Stainless steel housing with an integrated Ex barrier, for outdoor and classified areas alike.
What the system is built from
Installed in a safe-area rack, consolidating several repeaters with low insertion loss and leaving power and capacity headroom for the long fibre extension.
Divides the signal by process unit, tank farm and perimeter, so an area can be isolated during an incident and phases can be added over time.
A flameproof enclosure can be installed inside the classified area; fibre entry means no long RF feeder is run on site.
A passive antenna in a stainless steel housing with an integrated barrier, resistant to salt spray and corrosion, usable outdoors and in classified interiors — fewer spare types to hold.

Zone 1 and Zone 2 classified areas in chemical, oil and gas, and pharmaceutical sites.
Fiber carries signal into hazardous areas without RF power on the cable, simplifies routing and reduces losses over long distances.
Yes. Ex-rated ORUs connect to the same master unit as standard ORUs in control rooms and offices.
