New paper highlights spectrum regulatory approach for governments as mobile and satellite industries converge
12th September 2025, London: The GSMA today launched a new public policy paper on spectrum considerations for D2D services, providing governments with guidance for this emerging technology. D2D connects mobile handsets directly to satellites, supplementing coverage from terrestrial mobile networks and enhancing network resilience. D2D can have a positive impact if national regulations protect against harmful interference into mobile networks, which serve 5.8 billion people globally.
To shape best practice on D2D, the GSMA Board launched a spectrum task force in 2024 – bringing together over 50 mobile and satellite operators. The paper draws from those discussions and offers governments practical, near-term guidance.
John Giusti, Chief Regulatory Officer at the GSMA, said:
“Direct-to-device satellite connectivity has the potential to extend the reach of mobile, strengthen resilience and deliver real societal benefits. But without careful and balanced regulation, it risks disrupting the very mobile services that billions of people rely on every day. Our guidelines are designed to help governments embrace innovation while protecting the foundations of the mobile ecosystem.”
Extending mobile coverage
Today 57% of the world’s population is connected to mobile broadband and D2D can add resilience and supplement their services when they travel to areas with no connectivity, such as deserts, oceans, or mountains.
It can also help connect part of the unconnected who live outside coverage of mobile broadband networks (the coverage gap), estimated at 4% of the global population.
Crucially, 39% of people live within mobile coverage but are not connected (the usage gap) because of issues such as affordability and digital literacy. Addressing both the lack of coverage and usage are essential to achieving the industry vision of connecting everyone.
Satellite’s strength lies in its ability to reach remote areas. It cannot provide the capacity that terrestrial mobile networks can deliver, but with the correct regulation, D2D can supplement terrestrial mobile coverage.
Two distinct spectrum paths
D2D services can operate in two different types of spectrum, each with unique regulatory implications:
Using mobile (IMT) spectrum:
- Enables the use of standard handsets.
- Requires commercial agreements between mobile network operators (MNOs) and satellite operators.
- Means regulators can ensure access derives from existing licensed MNO spectrum.
- Benefits from following early regulation from countries such as the US, Canada and Australia which authorise MNOs to share their spectrum under their existing licences.
Using mobile satellite service (MSS) spectrum:
- Handsets must include specialised chipsets, currently limited to a small number of high-end devices.
- While it may not be necessary for satellite operators to join forces with mobile operators, users are likely to adopt services more seamlessly where commercial partnerships are in place.
- 3GPP has already standardised several MSS bands, but widespread adoption in devices is still lacking.
Priorities for policymakers
The GSMA’s paper highlights that governments considering early D2D regulation should:
- Protect mobile networks by requiring D2D operations to prevent interference with existing mobile services domestically and across borders.
- Support commercial partnerships between MNOs and satellite operators to benefit both industries and consumers.
- Ensure regulatory consistency by updating any early national rules with forthcoming WRC-27 outcomes to avoid fragmentation.
- Recognise handset availability limits, especially for MSS-based D2D, when setting policy expectations.

About GSMA
The GSMA is a global organisation unifying the mobile ecosystem to discover, develop and deliver innovation foundational to positive business environments and societal change. Our vision is to unlock the full power of connectivity so that people, industry, and society thrive. Representing mobile operators and organisations across the mobile ecosystem and adjacent industries, the GSMA delivers for its members across three broad pillars: Connectivity for Good, Industry Services and Solutions, and Outreach. This activity includes advancing policy, tackling today’s biggest societal challenges, underpinning the technology and interoperability that make mobile work, and providing the world’s largest platform to convene the mobile ecosystem at the MWC and M360 series of events.
