En fait, le lien isprevew ne fonctionne pas chez moi, mais celui-là, oui :
https://5gstore.com/blog/2026/03/26/starlink-direct-to-cell-150mbps/Donc en fait, on apprend que Starlink lancerait courant 2027, avec Starship, dont un premier lancement a réussi il y a quelques jours, une nouvelle génération de satellites en ultra low orbit, entre 326 et 335 km. Et que ces satellites seraient équipés pour utiliser la bande de fréquence S, pour la bande 5G n256, en FDD, dont les fréquences sont pour l'uplink de 1880 à 2010 LHz, et pour le downlink de 2170 à 2200 MHz, soit 30 MHz de largeur de bande. Et ce qui est important, c'est que ces fréquences sont normalisées partout dans le monde pour l'usage des satellites. Ce qui veut dire qu'ils n'utiliseraient ni les fréquences 1800 MHz, ni les 2600 MHz.
Il y a un petit résumé des caractéristiques de cette bande qui est donné par Gemini quand on fait une recherche Google :
3GPP band n256 is a 5G and LTE Non-Terrestrial Network (NTN) frequency band designated for satellite communications, utilizing the S-band (around 2 GHz).
Frequency Specifications
Uplink (UL): 1980–2010 MHz
Downlink (DL): 2170–2200 MHz
Duplex Mode: Frequency Division Duplex (FDD)
Channel Bandwidths: 5 MHz, 10 MHz, 15 MHz, and 20 MHz
Key CharacteristicsApplication:
Designed for direct-to-device satellite mobile services (MSS) and satellite IoT.
Standardization: Introduced in 3GPP Release 17 for 5G NR NTN.
Global Harmonization: S-band spectrum is widely allocated across all ITU regions for satellite use.
A noter que dans les largeurs de bande possible, on n'a pas 30 MHz...
Starlink espère pouvoir faire une première expérimentation fin 2027, ce qui coïnciderait aussi en France à la finalisation de l'étude des autorités de la concurrence pour le rachat de SFR.

What’s Driving the Speed Jump
The path to 150 Mbps runs through two major developments: spectrum and satellites.
SpaceX entered into a $17 billion agreement with EchoStar to acquire AWS-4 and H-Block licenses, granting the company 50 MHz of dedicated mid-band capacity. Pica summarized it well at the ITU event: “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 — cellular broadband use cases, like AI or daily connectivity needs.”
On the satellite side, SpaceX has filed with the FCC to launch an additional 15,000 satellites into Very Low Earth Orbit at altitudes between 326 km and 335 km. The current D2C constellation spans only about 650 satellites. That scale-up is what makes the 150 Mbps target plausible rather than just aspirational.
The upgraded service is also expected to leverage both Mobile Satellite Services spectrum at the 2 GHz band and ITU spectrum for expanded coverage, with timing designed to align with chipset readiness for 3GPP band n256. SpaceX is reportedly working with manufacturers like Qualcomm and MediaTek to bake Starlink connectivity directly into future phone modems — meaning no special hardware, just your existing phone.
Timeline: When Does This Actually Happen?
SpaceX is targeting late 2027 for initial testing of the upgraded service, tied to the official closure of the EchoStar spectrum deal. The new V3 satellites required for this service will be launched aboard the Starship rocket, which is capable of carrying significantly larger payloads than the Falcon 9 currently used for Starlink launches.
SpaceX has already expanded its carrier partnerships well beyond T-Mobile, working with Rogers in Canada and KDDI in Japan. The longer-term vision, as Elon Musk has hinted publicly, is a single global Starlink Mobile subscription that works everywhere — no roaming agreements required.
