Musk forwarded a post from Starlink’s official account saying: “Starlink Mobile’s next-generation satellites will provide 5G speed services from space, with data density 100 times that of the current V1 generation satellites.
V2 satellites will support streaming, web browsing, high-speed applications and voice calls seamlessly, just like connecting to terrestrial networks. "

On January 9 this year, the U.S. Federal Communications Commission (FCC) officially approved SpaceX to deploy an additional 7,500 second-generation Starlink satellites. So far, SpaceX has received official authorization for a total of 15,000 second-generation Starlink satellites.
The second generation of Starlink satellites has significant technical advantages compared to the first generation, including supporting higher communication capacity, lower signal delay, adopting more advanced satellite configurations, and adding new operating capabilities to support multiple frequency bands such as Ku, Ka, V, E, and W.
These upgrades not only enable the satellite to be compatible with both fixed satellite services and mobile satellite services, but also further optimize signal coverage and stability through key measures such as lowering the orbital altitude (the new orbital shell range is from 340 kilometers to 485 kilometers), significantly improving service performance and user experience.
