AT&T and AST SpaceMobile complete first cellular to satellite network handoff
Engineers in Washington state have completed what they describe as the first successful live handoff between a terrestrial cellular network and a direct-to-device satellite link. The demonstration by AT&T and AST SpaceMobile allowed standard mobile devices to maintain connectivity as they moved beyond the reach of ground towers. If deployed commercially, the architecture could eliminate dead zones on highways and remote regions without requiring specialized hardware.
