SpaceX's bold Starlink redesign could connect smartphones directly to space

SpaceX has submitted plans to the US Federal Communications Commission (FCC) for a major redesign of its Starlink network. The proposal involves launching 15,000 satellites into Very Low Earth Orbit (VLEO), just 300 kilometres above the planet. This shift aims to improve mobile connectivity for standard smartphones without modifications.

The revised architecture, called 'Gen3/MSS', focuses on reducing signal delays and boosting network capacity. By operating closer to Earth, the satellites will cut latency and allow more efficient frequency reuse. This would support mass-market voice and data services, including direct-to-cell (D2D) connections for everyday mobile phones.

The lower altitude comes with challenges. Satellites in VLEO face stronger atmospheric drag, forcing them to use constant propulsion to stay in orbit. SpaceX estimates it may need to launch thousands of replacement units each year to maintain a fleet of 15,000 satellites, as orbits decay faster at this height. The FCC has confirmed that SpaceX’s application meets initial technical criteria and has opened a 30-day public consultation. During this period, competitors and stakeholders can submit objections or concerns. Rivals like AST SpaceMobile and Amazon’s Project Kuiper may raise issues about interference and collision risks in the crowded lower LEO bands.

The FCC’s review process will determine whether SpaceX can proceed with its VLEO expansion. If approved, the new constellation could significantly change global mobile connectivity by linking unmodified smartphones directly to space-based networks. The decision will also shape competition in the low-orbit satellite sector.
