After many years of regulatory, standardization and technical implementation activities, the United States' dynamic, three-tiered, hierarchical framework to coordinate shared use of 150 MHz of spectrum in the 3.5 GHz CBRS (Citizens Broadband Radio Service) band has finally become a commercial success. Although the shared spectrum arrangement is access technology neutral, the 3GPP cellular wireless ecosystem is at the forefront of CBRS adoption, with more than half of all active CBSDs (Citizens Broadband Radio Service Devices) based on LTE and 5G NR air interface technologies.
