Push To Talk over Cellular

Mission-critical voice for field teams. Replace ageing LMR / TETRA / radio with broadband PTT over LTE, group calls, dispatch consoles, presence, all on a smartphone or ruggedised handset.

The shift

From narrowband LMR to broadband PoC.

LMR and TETRA networks served public safety and industry well for 30 years. They are also narrowband, expensive to extend, and carry voice only. Push To Talk over Cellular (PoC) replaces them with a broadband service that runs on commercial LTE/5G, voice, video, location, messaging on one device.

Sub-second call setup

Sub-second call setup

MCPTT-compliant call setup under 300ms floor-to-floor. Faster than LMR in many real-world deployments.

Group and broadcast calls

Group and broadcast calls

Pre-defined talk groups, dynamic talk groups, broadcast calls. Configure by role, location or incident.

Dispatch and presence

Dispatch and presence

Web-based dispatch consoles with mapping, location history, recording. See who is online, who is talking, who is in trouble.

Standards

3GPP MCPTT, not vendor lock-in.

The 3GPP Mission Critical Push To Talk standard (TS 23.379 and friends) gives you a vendor-interoperable specification. We build on it; you are not locked into a single vendor’s PBX or radio.

01

MCPTT (Mission Critical Push To Talk)

The 3GPP standard. Floor control, late-entry calls, pre-emptive priority. Used by FirstNet in the US, ESN in the UK, and similar public-safety networks in Europe.

02

MCVideo and MCData

Companion standards for mission-critical video and data. Real-time video from a bodycam, file transfer to a field team, all on the same MC architecture.

03

Interworking with LMR

Where LMR is still in service, gateways bridge PTT calls between broadband and narrowband networks. Migration does not have to be a flag day.

Who this is for

Field operations that still depend on radio.

Public safety

Police, fire, EMS. Broadband mission-critical voice on dedicated spectrum, interworked with existing LMR.

Utilities and transport

Power grid crews, rail maintenance, port operations. Replace vendor-locked radios with standards-based broadband voice.

Enterprise field teams

Security teams, facilities, logistics, hospitality. Cross-network PTT, your team on any carrier, one app, one console.
