New satellite D2D-IMT research note added

Mobile network operators around the world are teaming up with satellite companies such as SpaceX (Starlink), AST SpaceMobile and Lynk Global to develop direct-to-device (D2D) services based on licensed mobile spectrum.

D2D-IMT promises service continuity in places beyond the reach of terrestrial mobile networks, such as in remote and mountainous areas, but will regulators allow supplemental satellite-based coverage to count towards mobile operators’ network rollout obligations, now or in the future?

So far, the FCC’s D2D-IMT framework has ruled this out, and Canada’s forthcoming rules similarly bar service providers from counting satellite-based D2D-IMT coverage towards their mobile network construction requirements.

However, satellite-based networks have long been touted as the best way to provide coverage in the most sparsely populated and difficult-to-reach areas that are uneconomical to cover with terrestrial mobile networks. And with satellite D2D, expensive satellite terminals are no longer required; the service is designed to work with unmodified smartphones.

This suggests it’s time for regulators to weigh up how new services such as D2D-IMT can contribute to improving mobile coverage and plan ahead for any regulatory work that’s required.

The new research note is now available to Spectrum Research Service subscribers.
