The Federal Communications Commission (FCC) has voted to modernize its satellite spectrum-sharing rules, a significant move that could increase satellite internet capacity by up to sevenfold. This decision, made on Thursday, aims to enhance the broadband experience for millions of Americans by enabling faster speeds, lower costs, and greater reliability. The FCC's update comes as a revision of the Equivalent Power Flux Density (EPFD) framework, which was established in the late 1990s to prevent interference between low-Earth orbit (LEO) satellites and higher-orbiting geostationary satellites. The original rules limited energy transmission from LEO satellites, slowing broadband speeds. SpaceX, which operates the largest satellite internet constellation, argued that these restrictions hindered next-generation satellite operations. In contrast, Viasat expressed concerns that loosening these rules would lead to increased interference and further monopolization by SpaceX. However, the FCC concluded that modern satellite designs facilitate better spectrum sharing. Tests indicated that LEO systems could increase satellite numbers serving a region by 700% without significant interference. This advancement is expected to benefit not only SpaceX but also other companies like Amazon, which is launching 3,000 satellites for its Project Kuiper constellation, and AST SpaceMobile, which is developing a space-based cellular network. The new regulations are poised to improve internet access for underserved communities, making high-speed broadband more accessible.
