Shared-Spectrum D2D Model Aims for Open Access

A new approach to direct-to-device (D2D) connectivity proposes satellites as shared infrastructure—much like terrestrial cell towers—coordinated by a shared spectrum D2D ecosystem rather than a single vertically integrated player. The concept aggregates mobile satellite spectrum already allocated across scores of markets, aiming to deliver consumer-grade messaging first, then data services, within a three-year window.
Under this model, multiple participants contribute spectrum while retaining ownership, with operations orchestrated to maximise regional availability and uphold national sovereignty. Technically, the blueprint combines in-orbit assets with new Low-Earth Orbit capacity, stitching them through common standards and interoperable gateways. The draw for policymakers is clear: an open framework that lets countries and spectrum holders participate on equitable terms without ceding control.
For the wider market, shared access reduces duplication and lowers the barrier to entry for mobile network operators, chipmakers, device OEMs, and app providers. Adoption hurdles remain—while 3GPP now includes several MSS bands, handset support is still concentrated in higher-end models—but a phased service plan (starting with SMS/MMS and short media, expanding to IP data) can ramp usage as device compatibility broadens.
The industrial upside is immediate. Infrastructure and IoT estates gain resilient, standards-based fall-back for telemetry, alarms, and control where terrestrial reach is patchy. Disaster Recovery teams benefit from an on-ramp that works on ordinary smartphones, enabling coordination when fibre and cellular fail. Maritime corridors, remote workforces, and transport routes can all exploit ubiquitous coverage without bespoke satellite handsets.
Success hinges on governance as much as radios. Clear rules for spectrum coordination, lawful intercept, roaming, and interference mitigation are essential, alongside common APIs for provisioning, billing, and network slicing. Security baselines must cover device attestation, fraud controls, and end-to-end encryption, while performance SLAs should reflect realistic capacity during surge events.
If executed well, the architecture could complement national strategies seeking vendor diversity and sovereign control, while accelerating handset-native satellite capability across the ecosystem. With timelines ambitious and details still emerging, the prize is a more inclusive market—one where multiple providers interoperate on shared infrastructure inside a shared spectrum D2D ecosystem.
