Mobile World Congress 2026 is the world's largest and most influential connectivity event, serving as the global stage for the mobile and telecommunications industry. Organised by the GSMA, the international trade body representing mobile network operators and the broader mobile ecosystem, the congress takes place from 2–5 March 2026 at the Fira de Barcelona Gran Via and attracts over 100,000 attendees from more than 200 countries.
While Mobile World Congress covers the full spectrum of connectivity and mobile technology, it features extensive smart city tracks that are highly relevant to urban innovation professionals. Key themes include 5G and beyond-5G applications for urban environments, IoT infrastructure and sensor networks powering smart city services, connected and autonomous transport systems, digital twin technology for city-scale planning and management, edge computing architectures for real-time urban data processing, and the role of mobile platforms in transforming public services such as healthcare, education, and citizen engagement.
The congress combines a massive exhibition with a world-class conference programme featuring heads of state, industry chief executives, and leading technologists. Dedicated zones for start-ups, innovation showcases, and ministerial programmes ensure that participants at every level of the ecosystem find relevant content and networking opportunities.
This event is essential for smart city strategists, telecommunications professionals, urban technology providers, and policymakers seeking to understand how next-generation connectivity will reshape urban life. Barcelona's long-standing partnership with the GSMA and its reputation as a global smart city capital make it the ideal host. Mobile World Congress serves as the definitive annual gathering for the technologies and partnerships that will underpin the connected cities of the future.
