Telecommunications regulators and satellite operators are aligning on direct-to-device (D2D) spectrum allocation protocols. By incorporating Non-Terrestrial Network (NTN) specifications into consumer baseband processors, handset manufacturers are eliminating the need for specialized external antennas.
Bandwidth Constraints and Spectrum Allocation
Initial D2D deployments are restricted to low-bandwidth text messages, emergency SOS, and telemetry. Network modeling indicates that while broad messaging functionality is achievable, supporting voice and low-bitrate data services will require next-generation satellite constellations with larger phased-array apertures.
