Restricted-zone access & geofencing.
Keep people out of hazardous and secure zones, and tie permit-to-work to live presence. Access is granted or refused on who's certified to be there — and every breach is logged.
Restricted-zone access & geofencing: how it works, and what it prevents.
The right radio for the job — chosen, never sold — mapped to your use case. That is what makes the ROI fast.
1 · Define zones
Hazard and secure areas are drawn as live geofences, each with its own rules.
2 · Check presence + permit
A tag's identity and permit status are checked the instant it nears a zone.
3 · Enforce & log
Unauthorised entry triggers an alert (and can interlock equipment); every event is auditable.
UWB → precise boundaries · BLE → broad presence
Which technology actually fits.
We have no hardware to sell, so the recommendation serves your outcome — not a price book.
UWB
Accurate zone boundaries.
BLE
Broad presence detection.
Permits
Live permit-to-work link.
Industries this solution suits
Right person, right zone — or no entry.
An energy site geofences its hazardous and secure areas. A worker's tag and permit are checked as they approach; an unauthorised entry raises an alert and can interlock the equipment, and every event is logged.
Typically bought by: EHS, permit-to-work owners, security, operations.

Frequently asked questions
How does restricted-zone access with geofencing work?
Worn tags are detected entering or leaving defined zones; the system can warn, log, or trigger access control - enforcing who is allowed where without physical barriers everywhere.
Is it different from card access at doors?
Yes - it is continuous and spatial, covering open areas, hazardous zones and soft boundaries that doors and card readers cannot, and it knows who is inside, not just who badged in.
What accuracy and technology fit?
UWB for tight, safety-critical geofences; BLE or Wi-Fi for broader zones. We tune zone size to balance enforcement against nuisance alerts.
Does it integrate with access control and safety systems?
Yes - it complements your access control, PA and safety systems, and can feed mustering and lone-worker use cases on the same infrastructure.
Where is this most valuable?
Hazardous areas, restricted or secure zones, machinery exclusion zones, and any site where being in the wrong place is a safety or security risk.
