The Catalan government has launched Spain’s first mobile telecommunications unit designed to restore phone coverage in areas hit by emergencies. Presented this week, the vehicle is intended to keep impressive services and public alerts operational when fires or storms damage infrastructure and disrupt regular networks. The move follows the widespread blackout that struck the region in April 2025 and exposed vulnerabilities in emergency communications.
Developed with an investment of €422,500, the vehicle provides voice and data services across 4G and 5G networks. It can connect to any available telecom tower or switch to satellite connectivity using Starlink technology if necessary. Designed for rapid deployment in rural or hard-to-reach locations, the system offers a coverage radius of 10 to 20 kilometers and up to 48 hours of autonomous operation, powered by its onboard generator.
Officials from the Generalitat, including Albert Tort, Secretary of Telecommunications and Digital Change, and Imma Solé, Deputy Director of Civil Protection, stressed that the unit cannot replace existing infrastructure. It is a temporary solution to bridge gaps during crises. The project is a public-private partnership involving the Generalitat, Telefónica, Vodafone and MasOrange, intended to strengthen the ability to recover of Catalonia’s communications network.
During emergencies such as wildfires, which can destroy cables and towers, the mobile unit acts as a repeater, restoring connectivity for residents and emergency teams. That can help maintain the cellular transmission path ES-Alert depends on. The system sends emergency messages through 4G and 5G base stations to compatible phones in selected coverage areas, without requiring a separate app. As Carlos Sánchez, an author at The Conversation España, explains, alerts go directly from mobile-network base stations to compatible devices within their coverage area. Because the system targets cells rather than exact administrative boundaries, alerts can reach beyond a hazard zone or fail to cover every affected location. The incident was covered in detail in this report on emergency restrictions in the Pyrenees.
The need for resilient communications is clear from the frequency of public warnings. An analysis by Newtral using Civil Protection data counted 587 ES-Alert activations in Spain from 2023 through October 19, 2026. Forest fires accounted for 276 activations, or 47%, while rain and snow prompted 178, or 30%. Catalonia recorded 221 alerts over that period, the highest total among Spain’s autonomous communities, with fires the leading cause there. In 2026 alone, Spain recorded 352 activations through October 19. Catalonia accounted for 124, also the highest regional figure.
The Generalitat plans to keep the unit operational throughout the year, initially focusing on the high-risk summer season. Future adjustments to the service will depend on operational needs and the frequency of incidents. The budget covers the vehicle and generator, along with ongoing deployment, operation and monitoring services.
Spain’s mix of urban centers and remote rural areas makes reliable mobile coverage a persistent challenge during disasters. The Catalan initiative fits a broader European trend of investment in infrastructure built to withstand extreme weather and technical failures. Catalonia’s deployment is part of its effort to protect communications and public safety as climate and infrastructure risks grow.
