The Critical Communications Review reports that MWC 2026 marked a pivot point for the critical communications industry. The UK Emergency Services Network is replacing Airwave/TETRA, France is building the Réseau Radio du Futur on 4G/5G MCX, and Germany’s BDBOS is evaluating its broadband evolution roadmap. The review frames MWC as now directly relevant for public safety professionals tracking the sector-wide TETRA-to-MCX transition in Europe.
