The dispute concerns the 1.6GHz and 2.4GHz bands, which Globalstar already uses for its satellite communications services, including the iPhone 14’s Emergency SOS feature. Last week, SpaceX Requested FCC to reach the same spectrum so that starlink It can provide connectivity to mobile devices.
Globalstar initially remained silent about how it would respond to SpaceX’s plan. But on Thursday, the company I sent(Opens in a new window) its own public file to the FCC, asking it to deny access to spectrum.
“The Commission must reject this application, which lacks sufficient technical justification, goes against the Commission’s established precedent, and threatens important public interest promotion services including emergency services that have been provided by Globalstar and its partners for more than two decades,” the submission said.
Globalstar’s main problem is the potential for SpaceX to cause interference to communications with its satellite systems. “SpaceX has provided neither data nor assessment, nor has it demonstrated that the addition of proposed SpaceX operations within the spectrum licensed to Globalstar could occur without creating a significant and unacceptable risk to the Globalstar MSS (Mobile Satellite Service) network and its customers,” he says.
Globalstar also argues that it needs protected access to the 1.6/2.4 GHz bands, given that the company will now power emergency satellite connectivity in order to iPhone 14, which are expected to be sold to millions of consumers. The company is also wondering why SpaceX will require access to the 1.6/2.4 GHz band when it can continue to access other radio spectrum.
“Based on the scant data provided to date, SpaceX has not demonstrated that successful coordination between Globalstar and SpaceX is possible or that harmful interference would not be expected from SpaceX operations to Globalstar’s MSS network,” the file adds.
Globalstar resistance is preparing to ignite a regulatory battle that could delay SpaceX’s plans for satellite mobile service through Starlink unless the Federal Communications Commission makes a decision soon. Elon Musk’s company plans to Use(Opens in a new window) The 1.6GHz and 2GHz bands are for download purposes while the 2.4GHz spectrum will be used for the downlink. It is also developing a modular payload that can be linked to Starlink satellites to communicate over the required radio bands.
SpaceX did not immediately respond to a request for comment. But in her private file last week, the company pointed(Opens in a new window): “Globalstar has exclusive access to parts of the 1.6/2.4 GHz bands, although the panel did not provide Globalstar with permanent exclusive use of the bands.”

The SpaceX file also confirms that it can operate in the 1.6 / 2.4 GHz bands without causing interference through proper coordination with other satellite providers and the use of various technologies in the Starlink constellation.
However, Globalstar argues: “The opaque data provide no basis for the Commission’s work, especially when harmful interference could overturn Globalstar’s life safety services for consumers and cause irreparable harm to Globalstar MSS’s business.”
The company adds: “Globalstar is keen to compete with MSS systems operating on unused or otherwise available spectrum, but the Commission should reject unfounded requests that would undermine regulatory certainty and stability and threaten harmful interference with Globalstar’s systems.”
