When communication fails in a hazardous environment, the consequences can be catastrophic. That's why Mission Critical Push-to-Talk (MCPTT) isn't just an upgrade from basic push to talk — it's a fundamental shift in how safety-critical industries stay connected

Unlike standard Push-to-Talk over Cellular (PoC), MCPTT is built to 3GPP standards with network prioritization, dedicated emergency channels, end-to-end encryption, and full dispatch/command center integration. In short: it works when everything else is under pressure.

At Exloc Instruments, we supply i.safe MOBILE's certified 4G/5G devices — including the IS380.x and IS440.x series — purpose-built for ATEX-rated hazardous areas and fully compatible with leading MCPTT platforms.

Who needs MCPTT?
✅ Oil & gas and chemical facilities in ATEX zones
✅ Emergency services and public safety organizations
✅ Utilities and transport infrastructure
✅ Defense and government agencies

Analogue networks are being phased out. TETRA infrastructure is ageing. The migration to MCPTT over LTE and 5G is happening now — and procurement decisions made today need to cover the full technology cycle.
