Forty years after making the UK’s first mobile phone call, Vodafone has marked another milestone. They’ve accomplished the world’s first non-terrestrial video call using a standard, unmodified 4G/5G smartphone via AST SpaceMobile’s BlueBird satellites. This historic event highlights cellular and satellite network convergence, a critical innovation for extending mobile coverage to remote areas.
Back in 1985, Vodafone founder Sir Ernest Harrison made the UK’s first mobile phone call. Now, Vodafone’s engineer, Rowan Chesmer, successfully video called CEO Margherita Della Valle from Wales’ remote mountains. This area had previously lacked mobile broadband access. Significantly, the call didn’t require any special equipment, demonstrating seamless integration between space and terrestrial networks. The service claims to provide users with a similar experience to existing 4G and 5G networks.
AST SpaceMobile successfully launched its first five BlueBird satellites in September, which are positioned in low Earth orbit for commercial non-terrestrial network (NTN) services. BlueBird satellites, designed to handle up to 120 Mbps data speeds, rely on strategic investments from tech giants like Google and Rakuten. Government contracts and over 45 global mobile carriers, including Vodafone, AT&T, Verizon, Orange, and Telefonica, showcase widespread industry backing.
The satellite industry has embraced cellular and NTN convergence, dubbing it the “Great Convergence.” Although technical and business obstacles exist, NTNs offer promising extended reach. They can enhance coverage for basic 4G/5G services across difficult terrains and simplify 5G roaming and backhaul support.
Margherita Della Valle emphasized the impact of this breakthrough, stating, “Vodafone’s job is to get everyone connected, no matter where they are. Our advanced European 5G network will now be complemented with cutting-edge satellite technology.” She highlighted its potential to bridge the digital divide, enhancing connectivity for rural areas and during emergencies.
