CTO ELMAR GRASSER ON SUNRISE ' S 4G AND 5G STRATEGY
Sunrise is the first operator in Europe to run exclusively on 4G and 5G, supported by a nationwide 5G Standalone( SA) network in Switzerland. After entirely shutting down 3G and retiring 2G, Sunrise reallocated valuable spectrum from legacy technologies to modern networks. The shift delivers stronger indoor and rural coverage while transferring traffic from 4G to 5G, improving efficiency and performance for all customers. With 5G smartphones now connecting directly to the 5G core, users benefit from lower latency, longer battery life and a more consistent experience.
Launching 5G Standalone( SA) marks more than just a technical milestone, it’ s a powerful statement of Sunrise’ s commitment to innovation, customer experience, and sustainability. By using fewer resources per unit of data, the network consumes less energy, representing a meaningful step toward greener networks.
Beyond everyday improvements in coverage and capacity, Sunrise’ s 5G SA network lays the groundwork for next-generation applications – from industrial automation and immersive entertainment to mission-critical communications – transforming the way people and businesses connect.
