Making TETRA-MCX Interworking work - assessing the alternative options

12 May 2026

From the TCCA Critical Updates Webinar Series


This webinar took place at 10.00 CEST on Tuesday 12 May 2026

The presentation slides, recording and and Q & A are available below.

The Interworking Function (IWF) interface provides a standards-based way to connect TETRA systems with mission critical MCX broadband systems.

Not all TETRA system vendors are implementing this standard-based IWF interface on their TETRA system.

In this webinar vendors presented alternative ways to connect your TETRA system with MCX using the standard-based IWF and as an alternative the TETRA standard-based Intersystem Interface (ISI) or proprietary console APIs.

These (and other) solutions will be demonstrated live a few weeks later at the IWF Focus Forum during Critical Communications World (CCW) in London, taking place from 16-18 June 2026.
