On August 12, 2026, the Brazilian National Telecommunications Agency (ANATEL) issued Act No. 10,400/2026 regarding the latest regulations for 6 GHz Wi-Fi. These new regulations automatically replace Act No. 14,448, which was previously issued on December 4, 2017.
The latest regulations for 6 GHz Wi-Fi narrow the available frequency range. The remaining frequency bands will be allocated as a reserve for IMT and cellular services, including future 5G-Advanced and 6G networks.
Manufacturers, importers, and distributors who wish to market their devices in Brazil need to understand the latest regulatory changes regarding 6 GHz Wi-Fi. In this article, we’ll help explain the contents of these latest regulations and what you need to do to ensure your devices are compliant before the regulations officially take effect.
Changes to the New Regulation for 6 GHz Wi-Fi
Under Law No. 14,448, the frequency range authorized for Wi-Fi operations in the 6 GHz band was the full range of 5925–7125 MHz. This allocation represented 1,200 MHz of spectrum available for Wi-Fi use in Brazil.
Under the latest regulations for 6 GHz Wi-Fi in Law No. 10,400/2026, the allocated frequency range was reduced by 700 MHz. ANATEL removed the upper segment of 6425–7125 MHz. Currently, the Wi-Fi frequency allocation available for use in Brazil is 5925–6425 MHz, or 500 MHz.
Purpose of Spectrum Allocation
The complete reduction in Wi-Fi allocations is certainly not without reason. This is being done to align Brazil with international spectrum discussions following the 2023 World Radiocommunication Conference (WRC-23). At that conference, there was debate over how to divide the 6 GHz band between Wi-Fi and cellular broadband use.
ANATEL is considering the upper 6 GHz band for IMT and mobile services. This includes efforts to position the future deployment of 5G-Advanced and 6G.
The narrowing of the Wi-Fi allocation now serves as an expansion for cellular networks, which will be prioritized at the upper end of the band. This is also an effort to prevent unauthorized wireless use.
When Does This Regulation Take Effect?
Law No. 10,400/2026, which has been published, does not take effect immediately. Currently, the latest regulations for 6 GHz Wi-Fi are in a transition period. ANATEL certificates issued during this period may still refer to the previous regulations.
Moving forward, ANATEL expects manufacturers to begin adjusting their compliance with the new frequency range. These latest regulations will take effect on March 1, 2027.
Impact on Brazil Type Approval Certification
The narrowing of the 6 GHz Wi-Fi frequency range will certainly have a direct impact on Brazil type approval certification. This means that manufacturers of Wi-Fi 6E and Wi-Fi 7 devices will need to adjust to the applicable frequency bands.
During this transition period, it is advisable for products intended for the Brazilian market to begin adapting to the latest regulations for 6 GHz Wi-Fi. Operation in the 6 GHz band must be limited to the 5925–6425 MHz range, with operation in the 6425–7125 MHz segment disabled.
This needs to be done before these new requirements become mandatory. By adjusting these frequency restrictions, products will be better prepared to comply with the latest regulations well before March 2027.
