Spectrum in the 3.5 GHz band is expected to drive the first wave of fifth-generation (or “5G”) wireless broadband services, in large part because many countries have focused on harmonizing this spectrum for 5G use on an international basis. International harmonization of 5G spectrum in these frequencies would enable faster speeds, lower cost devices, and international roaming. The Federal Communications Commission (FCC) and the domestic mobile industry both recognize the benefits of revising outdating regulations governing the 3.5 GHz band that would hinder the use of this spectrum for 5G in the United States. When the current regulations were adopted, the FCC envisioned that the spectrum would be used like Wi-Fi, with hotels and coffee shops installing antennas indoors, and manufacturers and utility companies using it for industrial wireless systems (e.g., private video surveillance of a warehouse).
