SpaceX has reached an agreement to acquire cellular communication spectrum licenses from investment firm Grain Management for approximately $8 billion in cash, with both parties yet to comment on the transaction amount. This acquisition marks a significant step for SpaceX in entering the wireless communication market. The spectrum involved, operating in the 800 MHz band in the United States, can provide wireless services through terrestrial cell towers, helping Starlink services expand from broadband to wireless communications and addressing coverage gaps in indoor areas where satellite links are insufficient. Previously, the U.S. Federal Communications Commission (FCC) had approved SpaceX's application to launch up to 15,000 satellites dedicated to mobile communications. Once this acquisition is approved, SpaceX will provide connectivity services by combining its satellite constellation with terrestrial deployments. Earlier, SpaceX had partnered with T-Mobile to provide basic wireless connectivity in remote areas, acquired satellite spectrum usage rights from EchoStar, purchased some terrestrial cellular spectrum licenses, and proposed the idea of supporting mobile communication networks with small base stations. Following the news of the transaction, shares of leading U.S. mobile operators fell more than 6% in after-hours trading, while SpaceX's stock rose approximately 3% after hours. Previously, traditional U.S. telecom operators had joined forces to expand services in remote areas through satellite links to counter SpaceX's entry into the market.
