Softil says MCX off-network tech is now a global priority

Softil is pushing mission-critical communications vendors to adopt off-network capability as broadband group communications expand worldwide. The company points to an ETSI plugtest in France this week as a key step toward proving multi-vendor interoperability when cellular networks are unavailable.

Why it matters: - Mission-critical communications need to work when cellular coverage is weak or unavailable. - Off-network capability can keep first responders connected for voice, video, files, location and other critical data. - The shift affects a global market Data Bridge research estimates will reach $35.55 billion by 2029.

What happened: - Softil said MCX vendors should add direct-mode, off-network communications to support both on-network and off-network operation. - Pierre Hagendorf, Softil’s CEO, said first responders must be able to communicate whether a network is operational or down. - Softil said it was among the first companies to demonstrate an MCX off-network solution at the ETSI plugtest in 2023 with Alea, Leonardo Company and Qualcomm. - ETSI is holding its first dedicated off-network plugtest at its headquarters in Sophia Antipolis, France, on Nov. 3-6, 2026.

The details: - The plugtest is designed to validate interoperability and performance of multi-vendor MCX systems in real off-network scenarios. - Softil said the event is drawing MCX vendors and observers from around the world. - The MCX industry is also working within one of TCCA’s CCBG task forces to build a library of requirements and use cases for off-network MCX. - Softil said 5G Sidelink, standardized by 3GPP and developed by Qualcomm, enables direct-mode communication over 5G. - Softil said 5G Sidelink works with existing 5G networks and is part of the broader 5G evolution. - Softil said its BEEHD framework supports 3GPP MCX solutions, devices and products, along with rich media applications for enterprise and IMS/VoLTE. - Softil said more than 900 major corporations use its technologies. - Softil said its protocol stack portfolio includes IMS, Diameter, SIP and MSRP. - Softil included its website as More information.

Between the lines: - The push toward off-network capability suggests MCX buyers are moving beyond coverage assumptions and toward resilience planning. - The ETSI plugtest signals growing industry pressure to prove that vendor systems can interoperate when networks fail. - 5G Sidelink is emerging as a practical bridge between traditional network-based communications and direct device-to-device mission-critical use.

What's next: - Results from the ETSI plugtest should help clarify how ready the market is for off-network MCX deployments. - Work inside TCCA’s CCBG task forces is likely to shape requirements that vendors will have to meet for future products. - Broader adoption will depend on whether vendors can deliver reliable interoperability, resilience and seamless fallback across scenarios.

The bottom line: - Off-network capability is moving from a backup feature to a core requirement for mission-critical broadband communications.
