FCC Clears AST SpaceMobile for US Commercial D2D
The FCC has granted AST SpaceMobile commercial authority to deploy and operate its space-based cellular broadband network, marking a major regulatory milestone for direct-to-device (D2D) connectivity in the United States.
The approval allows AST SpaceMobile to launch and operate a low Earth orbit (LEO) constellation of up to 248 satellites, delivering Supplemental Coverage from Space (SCS) directly to unmodified smartphones. The system will utilise premium low-band spectrum in the 700 MHz and 800 MHz ranges, coordinated with key mobile network operator partners including Verizon, AT&T and FirstNet.
Low-band spectrum is particularly significant for D2D services, offering improved propagation and indoor penetration compared to higher-frequency alternatives. Combined with AST’s large satellite architecture, the approach is designed to support true cellular broadband from space rather than limited messaging services.
The authorisation also supports AST SpaceMobile’s broader global ambitions, enabling regulatory alignment for international deployments and use of multiple frequency bands for feeder links, telemetry and service delivery.
The decision highlights several key trends shaping the NTN landscape:
Regulatory maturity: National regulators are now granting full commercial approvals for D2D systems, moving beyond experimental licences
Cellular spectrum integration: Use of existing mobile bands reinforces alignment with terrestrial networks and 3GPP standards
Operator collaboration: Deep integration with MNOs positions NTN as an extension of existing cellular infrastructure
Strategically, the approval strengthens AST SpaceMobile’s position as a frontrunner in delivering broadband-grade connectivity directly to standard devices, differentiating its model from lower-capacity messaging-focused systems.
For US operators, the partnership model enables satellite coverage to function as a seamless extension of their networks, improving reach and resilience without requiring changes to user devices.
