The National Telecommunications Agency (Anatel) approved, through Act No. 8,991/2022 , the technical requirements and conditions of use for low-power ground stations in the 3.7-3.8 GHz band.

The Act approved the use of the band from 3.7 GHz to 3.8 GHz by stations of terrestrial systems, especially for private networks, indoor and outdoor , operating at low power and operational limits and engineering technicians who promote the appropriate conditions for the use and sharing of the radio frequency spectrum in that band
