Satellite-delivered broadband “offers particular promise,” advocacy groups said, urging the U.S. to push at the 2023 World Radiocommunication Conference for expanded spectrum access for low earth orbit constellations. In a letter Monday to the FCC, NTIA and State Department, the signatories said modernizing “outdated” ITU coexistence criteria would allow more-efficient and equitable access to shared spectrum. The signatories include the American Library Association, Benton Institute for Broadband & Society, Center for Rural Strategies, Information Technology Industry Foundation, Open Technology Institute at New America, Public Knowledge and R Street Institute.
