In the last three years, commercial interest in private 5G networks has increased worldwide, as a result of regulatory efforts to increase spectrum dedicated to industries and verticals, as well as specific needs for monitoring, automation and other services over broadband in business environments. The United States is one of the most advanced markets in this regard, with its dynamic sharing system in Citizens Broadband Radio Service (CBRS, 150 MHz in C band over 3.5 GHz), and the United Kingdom, Germany and Japan also granted "slices" of spectrum for actors outside the ICT sector. In Latin America, Chile submitted the possibility for consultation in 2019: there, the 28 GHz band was one of the most recommended; the Mining Council considered "critical" access to frequencies, and mobile operators outright rejected the initiative.
