Direct-to-Cell Technology: Enabling Satellite Connectivity for Legacy Devices

Direct-to-cell technology uses LEO satellites as spaceborne cell towers. It delivers LTE services to existing smartphones without hardware changes, bridging global coverage gaps. What Attendees will Learn How DTC works as a spaceborne cell tower — LEO satellites carry LTE eNodeB payloads in regenerative mode. How they serve unmodified phones using quasi-earth-fixed multi-beam antennas. How the satellite compensates for Doppler shift and time delay on thenetwork side. Why Doppler shift and round-
