Update – May 23, 2023: We have published a report detailing the technical performance of AST Space Mobile direct-to-handset LEO constellation. Click here for additional information. Different approaches are possible to enable Direct-to-Handset (DTH) satellite connectivity. For instance, there’s the approach by T-Mobile and SpaceX (see here) and by Apple and Globalstar (see here). AST SpaceMobile is taking… Read More »

T-Mobile + SpaceX Direct Satellite-to-Handset Service: Lots of Hype and Little Reality

This will start as a technical post, but I will relate it to practical and commercial conclusions at the end. T-Mobile and Space-X announced a partnership to provide direct satellite-to-handset service using T-Mobile PCS frequency band. While this is new to Space-X, there are other players in the industry working on the same objective, primarily AST SpaceMobile and… Read More »

Comparing LEO Constellations: How They Stack Up!

LEO constellations are set to introduce new dynamics in connectivity services. I’ve been looking to answer questions on the competitive or complementary nature of LEO with different types of terrestrial services such as fixed wireless access or long-haul transport. In process of the analysis, one needs to differentiate among LEO constellations since they are designed and optimized for… Read More »
