Two models for Direct-to-Device bid to reign in Earth-to-Space convergence

On one hand, there are systems operating over bands allocated to Mobile Satellite Services, such as those used by Viasat (L-band) and Omnispace (S-band). On the other hand, satellite operators transmit in spectrum allocated to terrestrial operators, a variation that requires significant regulatory changes and careful management to avoid interference.

Satellite-to-Phone or Direct-to-Device services are currently leading the announcements this year as the first examples of a future Earth-Space convergence. Indeed, as proposed during Satellite Map Day 2024, innovations in the coming years will be closely tied to Non-Terrestrial Networks (NTN), complementing 5G mobile networks, hybrid LEO-MEO-GEO satellite fleets, and High Altitude Platform Stations (HAPS).
