Pour compléter, selon PCMagazine Australie, Starlink prévoit avec ses nouveaux satellites v3, à terme, vers 2028, des débits maximum de 150 Mb/s par utilisateur. Ce qui sera vrai surtout dans les zones peu denses. Dans les zones denses, de façon réaliste, environ 18 Mb/s. Bien sur, pour l’instant seulement aux Etats-Unis où il a acquis 65 MHz dans la bande n256 (largeurs de canaux possibles, 5, 10, 15 et 20 MHz).
De manière un peu paradoxale par rapport à la situation actuelle, plus la zone sera peu dense, plus l'abonné aura de débit.
Il a eu l'opportunité d'acheter ces fréquences aux Etats-Unis (cher, 17 milliards de dollars), on peut penser que s'il a d'autres opportunités d'acheter ces fréquences NTN (Non Terrestrial Network), dans des pays avec une importante population, mais des zones de faible densité, un peu le cas de la France, il le fera. Là, on voit qu'ils pensent d'abord au Brésil, Chili et Mexique.
SpaceX's Cellular Starlink Aims for Speeds That Reach 150Mbps Per User
Updated Feb 25, 2026
A SpaceX policy manager mentions the goal at a conference as the company prepares to upgrade cellular Starlink with new satellites and additional capacity.
SpaceX this week offered more details on its plan to deliver 5G connectivity with its next-generation cellular Starlink service for mobile phones.
“We are aiming at peak speeds of 150Mbps per user,” SpaceX satellite policy lead Udrivolf Pica said at the International Telecommunication Union's Space Connect conference. “So something incredible if you think about the link budgets from space to the mobile phone.”
If SpaceX can hit its speed goal, the upgraded cellular Starlink service promises to deliver speeds close to those of traditional cell carriers' 5G networks on Earth. The median download speeds for T-Mobile’s 5G network currently reach 309Mbps while AT&T’s 5G network comes in at 172Mbps, according to Ookla’s Speedtest.net data.
SpaceX has been offering the service through T-Mobile’s T-Satellite, allowing users in cellular dead zones to remain connected. However, the current iteration of the cellular Starlink service has bandwidth constraints. Although it can power low-resolution video calls, texts, and select mobile apps using orbiting SpaceX satellites, download speeds only reach an estimated 4Mbps per user.
SpaceX is preparing to upgrade the technology by using newly acquired radio spectrum from Boost Mobile’s parent, EchoStar. In addition, the company has requested regulatory permission to launch another 15,000 satellites for the cellular Starlink service; the current system spans only about 650 satellites. The new system promises to unleash “video, voice, and data services, clearly,” Pica said during the panel.
On acquiring the EchoStar radio spectrum, Pica added, “More spectrum means a bigger pipeline, and this means that we can expand what we can do with partners. We can expand the quality of service. And again, we can do cellular broadband basically, cellular broadband use cases, like AI or daily connectivity needs.”
