The USA’s National Telecommunications and Information Administration (NTIA) has identified another potential piece of midband spectrum which could be opened up for shared usage by wireless operators. It has singled out 100 MHz in the 3.1-3.55 GHz band, specifically spectrum in 3.45-3.55 GHz, as “a good candidate for potential spectrum sharing, including the commercial power levels sought by the wireless industry”. The report follows a technical analysis released in January, that found “a clear possibility” for real time spectrum sharing to protect federal users, which run applications such as shipborne, airborne, and land-based radar. NTIA’s second main finding was that some sharing could be possible below 3.45 GHz, thougg this would be more difficult, it said, than in the higher portion of…
