AT&T and AST SpaceMobile demonstrate cellular-to-satellite handoff
AT&T and AST SpaceMobile demonstrated a handoff between cellular and satellite networks to keep phones connected as they move beyond tower coverage.
The test took place near Granite Falls, Washington, on October 21.
AT&T supplied the ground network, AST SpaceMobile the satellite network, and Ericsson and Nokia technologies to coordinate the transfer.
The system is designed to switch connections in milliseconds, reducing interruptions to calls and data.
It could extend mobile coverage in remote areas and places where towers are difficult to build or maintain.
The technology is not yet ready for widespread commercial use, and the companies have not announced a launch date.
Beta testing under real-world conditions is expected next to assess performance before commercial deployment.
AT&T and AST SpaceMobile demonstrated a handoff between a terrestrial cellular network and a direct-to-device satellite network.
The test took place near Granite Falls, Washington, on October 21 at 8:15 a.m. PT.
Ericsson and Nokia supplied technologies to coordinate the transition between the networks.
The companies say the approach could let phones switch coverage without dropping calls or data connections.
Further testing, including a planned beta phase, is expected before commercial deployment.
