SpaceX Secures Nationwide Low-Band Spectrum to Power Starlink Mobile
By Drooid · · How we work
Core Event
SpaceX announced a definitive agreement to acquire 100 % of Grain Management’s nationwide 800 MHz spectrum portfolio. The deal provides up to 14 megahertz of paired low-band frequencies, which SpaceX says will enable its Starlink Mobile service to combine satellite and terrestrial spectrum and compete directly with T-Mobile, AT&T and Verizon. The transaction remains subject to final approval by the Federal Communications Commission (FCC).
Background & Context
Starlink Mobile currently relies on a global 2 GHz mid-band spectrum that delivers high-bandwidth capacity. Low-band frequencies, such as the 800 MHz band, travel longer distances and penetrate walls and foliage more effectively, addressing a long-standing technical gap for satellite-based mobile networks. Earlier this year, the FCC approved SpaceX’s Gen2 constellation, authorizing the launch of 15,000 very-low-Earth-orbit satellites optimized for the 2 GHz band and granting access to the full range of backhaul bands (Ka/V/E/W). SpaceX argues that the addition of low-band spectrum will allow standard, unmodified handsets to connect without requiring proprietary satellite phones.
Timeline
- June 12, 2026 – SpaceX completes its initial public offering, marking a new phase of capital availability.
- October 8 – SpaceX publicly announces the acquisition of Grain Management’s 800 MHz spectrum portfolio, positioning Starlink Mobile for a full-scale U.S. carrier launch.
Data & Statistics
- Spectrum amount: up to 14 MHz of paired 800 MHz low-band spectrum.
- Satellite fleet: FCC approval for 15,000 Gen2 V2 satellites, delivering more than 100 times the bandwidth of the current generation.
- Market reaction: After the announcement, AT&T Inc. shares fell 6.75 %, T-Mobile US dropped 5.4 %, and Verizon Communications declined 5 % in after-hours trading.
Official Statements & Responses
In a post on X, CEO Elon Musk called the deal “a very big deal.”
Verbatim Quotes
- “With this new low-band spectrum and our Gen2 constellation, Starlink Mobile can now become the first network operator to deploy both satellite and terrestrial spectrum,” — Federal Communications Commission. SpaceX
- “This prime low-band spectrum addresses one of the key remaining technical gaps that will pave the way for Starlink Mobile to become a major mobile carrier in the US,” — Federal Communications Commission. SpaceX
- “This adds fuel to the fire in the battle between SpaceX and the mobile operators,” — TMF Associates' Tim Farrar, an industry expert
- “For nearly twenty years, we have built Grain to see opportunity where others see complexity,” — David Grain, founder and CEO
What’s Next
The FCC’s pending review of the spectrum transfer will determine the timeline for integrating the low-band frequencies into Starlink Mobile’s hybrid architecture. SpaceX has indicated that, once approved, it will begin deploying a terrestrial component to complement its satellite constellation, aiming to offer nationwide indoor and outdoor coverage without reliance on traditional cell towers.
