Transforming Mission Critical Communications in an Always-on World for Real-Time Situational Awareness

This blog is about the accelerating shift from legacy PMR to MCX networks, driven by 4G/5G maturity and the need for real-time voice, video, and data in public safety. It examines hybrid models and EU national programmes shaping this transformation.

 

From Narrowband to Mission Critical: How Public Safety is Reimagining Communications

The question is no longer whether the evolution from legacy PMR to MCX will happen, but how Public Safety Authorities are planning to achieve it.

The landscape of public safety, emergency response, and crisis management is undergoing rapid transformation of its communication services. Operations have become faster, more complex, and interconnected. As a result, the need for reliable, real-time information, data exchange (such as files, documents, etc) and video, has become essential for effective field operations.

From narrowband PMR to broadband mission critical

Historically, PMR networks – TETRA, P25, DMR, and others – fulfil their critical role: providing secured, reliable, and resilient voice and short messages (SDS) communications.

Evolution is now possible thanks to the maturity of mobile broadband technologies. 4G/5G networks make it possible to meet the rigorous requirements of critical communications – especially when reinforced by prioritization, pre-emption, security mechanisms and complemented, when necessary, by additional connectivity such as Wi-Fi or satellite connectivity (NTN).

Mission-Critical Services X or MCX — where 'X' means voice, video, and data — open the way to a new generation of fully prioritized, digital, and interoperable tactical operations.

Hybrid models leading the way: deployment and migration challenges

As organizations advance from legacy PMR systems to MCX systems, hybrid deployment models have emerged as the industry standard.

Hybrid models combine the use of the extensive radio coverage of commercial Mobile Network Operators (MNOs) with the deployment of a dedicated LTE/5G Core and application servers retained by PSA.

Leading transformation programs such as FirstNet in the United States and SafeNet in Korea were the early precursors of such hybrid model. Behind this hybrid model, two approaches stand out:

  • MOCN / MORAN - Interconnects MNO antennas to a PSA dedicated core network, either using MNO shared spectrum (MOCN) or integrated PSA-dedicated spectrum (MORAN).
  • F-MVNO - Leverages roaming between the PSA's core and the MNO core, providing a Full MVNO architecture for mission-critical deployments.

With hybrid models, reliance on the robustness of MNO radio networks could be foreseen as insufficient by user organizations (UO). Hardening of MNOs radio networks is a key topic for PSA. On that respect, some PSAs plan to reinforce MNO radio networks by reusing their existing TETRA radio network infrastructure, adding LTE/5G RAN equipment to extend coverage.

Additionally, PSA do require quality, priority, and pre-emption (QPP) for their UO on MNOs radio network. Note that reinforcement may include dedicated radio bubbles and satellite capabilities to further extend coverage and resilience.

Market View as 2026

This evolution comes with significant additional challenges. Service continuity requires guaranteeing uninterrupted service throughout the transition — a clear migration strategy is essential, encompassing phased rollouts, migration systems, infrastructure upgrades, training, and change management to ensure smooth user adoption and continued operations. Interoperability must allow not only for exchanges between MCX users and TETRA users, but also between MCX users and external user organizations having their own MCX system and interconnected cross-border user organizations (e.g. EUCCS). Security and data sovereignty requirements demand protection of sensitive communications and compliance with relevant regulations.

National programmes in Europe driving transformation

National programmes are driving modernization, showing how strategic investments in critical communications enable governments to address evolving operational challenges. Momentum is building across Europe:

France
ACMOSS (RRF) — now live
 
Finland
Virve 2.0 — progressing on migration
 
United Kingdom
ESN — integrating dedicated core & MCX
 
Sweden
SWEN — integrating dedicated core & MCX
 
Belgium
ASTRID — progressing strategy
 
Spain
SIRDEE — progressing strategy
 
Germany
BDBOS — progressing strategy
 
Netherlands
VMX — progressing strategy
 
Norway
DSB/NKOM — progressing strategy
 
Greece
Progressing strategy

 

In parallel, the European Commission is launching the EUCCS (European Cross-Border Critical Communications System) initiative. EUCCS aims to harmonize mission-critical communications across member states by providing a common framework for secure, interoperable, and sovereign services. EUCCS serves as a driver for national transformation programmes.

Expanding horizons: MCX as an enabler for innovation

The evolution to mission-critical communications goes beyond the transformation of the entire field operations, paving the way for innovation.

With MCX systems, critical communications are becoming true technology hubs, capable of aggregating in real time IoT sensors and connected professional accessories, CCTV systems, drones, autonomous robots, and mobile cameras. The use of video streams and IoT data opens the door to use cases enhanced by real-time analytics, automated alerts, and the ability to integrate AI features to assist operators in command centres.

This integration strengthens situational awareness, streamlines inter-agency coordination, and improves field operations responsiveness.

Improving cross-sector innovation for a resilient future

The global push toward Mission Critical communications is accelerating, as Public Safety, Defence, and Critical National Infrastructure programmes converge on broadband capabilities and interoperable architectures.

As Critical Network operators redesign their architectures, their decisions will set the foundations for user operations, investment priorities, and future partnerships with telcos. This creates a decisive moment for telcos to expand beyond connectivity and take on a key role in supporting Mission Critical transformations.

Mission Critical Communication platforms enable higher operational efficiency and real-time situational awareness, while opening the door to augmented use cases supported by advanced technologies such as 5G, AI, NTN and others.

This transformation explains why essential services are increasingly shifting toward models that rely more directly on digital and telecom innovation.
