SpaceX has signed an agreement to acquire low-band spectrum licenses nationwide as it seeks to transform Starlink Mobile into a broad mobile service in the U.S. The plan involves combining satellite connectivity with terrestrial network infrastructure.
The agreement covers up to 14 megahertz of paired spectrum in the 800-megahertz band. Completing the acquisition depends on final approval from the U.S. Federal Communications Commission.
Low-band frequencies will improve indoor connectivity
According to SpaceX, low-band frequencies will expand coverage inside buildings because their signals can penetrate obstacles such as walls. The company said most existing mobile devices support the band in question.
The low-band frequencies are expected to support the 2-gigahertz mid-band spectrum planned to provide high capacity for Starlink Mobile in the U.S. Following regulatory approval, SpaceX aims to combine its satellite-based mobile connectivity system with terrestrial infrastructure to provide connectivity indoors and outdoors, including in areas without cellular coverage.

Authorization granted for 15,000 satellites for the Starlink Mobile constellation
The Federal Communications Commission also approved SpaceX's application for its next-generation Starlink Mobile constellation this week. The decision authorizes the launch of 15,000 satellites that will use 2-gigahertz spectrum for global operations.
SpaceX said V2 Starlink Mobile satellites will offer more than 100 times the bandwidth of the current generation. The company also said the satellites will provide direct, high-speed connectivity to unmodified standard mobile devices.
The commission also authorized additional communications bands that will allow the satellites to use Starlink's existing terrestrial gateway system.
