Direct-to-Cell Technology: Enabling Satellite Connectivity for Legacy Devices - Wiley Science and Engineering Content Hub

Download this complimentary White Paper today! Non-terrestrial networks have moved from concept to commercial reality, with satellite-based emergency messaging already deployed. This white paper explains how direct-to-cell technology uses LEO satellites to deliver LTE connectivity to unmodified legacy devices — covering Doppler compensation, timing, spectrum, and the path to 5G NTN. What you will learn about:  How DTC places LTE base stations on LEO satellites. Satellites orbiting at 340 km to 570 km altitude that use phased array antennas with narrow beams to serve existing phones as spaceborne cell towers. Why Doppler shift and round-trip time create physical layer challenges. How spectrum sharing and regulatory frameworks enable DTC services. How the FCC SCS framework permits terrestrial and satellite operators to share spectrum, while MSS bands offer an overlay alternative. Where DTC fits on the path toward 5G NTN and 6G. How DTC is an interim solution for fast time-to-market satellite services and how NR-NTN will eventually replace it with purpose-built NTN capabilities. Click 'LOOK INSIDE' to Download Now.
