Mobile coverage for venues and Martyn’s Law
Make communication part of venue preparedness. Improve everyday mobile reception in the places staff, contractors and visitors need to use it.
Where mobile signal fails in venues
A venue’s internal rooms and service routes may have weak reception even when its entrance is well covered. During an incident, relying on one communication channel leaves a gap in the response plan.
Staff and steward areas
Assess the devices and channels used by the venue team.
Service routes
Include back-of-house rooms and agreed circulation areas.
How a distributed antenna system fixes venue coverage
We assess reception across the venue and install mobile coverage where staff and visitors need to communicate. The design fits alongside your radios, alarms, public address and emergency procedures, with clear coverage requirements and commissioning tests.
