Brazil ANATEL Act 14158 became mandatory on April 6, 2026, establishing comprehensive updates to testing requirements for wireless devices operating across multiple frequency bands. The regulation introduces coverage for the 116-246 GHz frequency range, revised emission limits for Wi-Fi systems, and shifts power measurement methodology from EIRP to conducted power for specific device categories.
ANATEL published Act No. 14158 on October 1, 2025, replacing and expanding the previous Act No. 14448/2017. The regulation updates technical requirements for radio frequency devices and test procedures, bringing Brazil's framework into closer alignment with ETSI and FCC standards. This modernization addresses emerging wireless technologies including Wi-Fi 6E, Wi-Fi 7, and advanced radar systems while maintaining Brazil's specific regulatory requirements for telecommunications equipment homologation.
Act No. 14158 introduces Section 25, establishing new requirements for devices operating in the 116 GHz to 246 GHz frequency range within the millimeter-wave and sub-terahertz spectrum. The regulation specifically authorizes operation in the 116-123 GHz, 174.8-182 GHz, 185-190 GHz, and 244-246 GHz bands with defined average and peak EIRP limits, while strictly prohibiting use on aircraft or satellites.
For Wi-Fi systems, the regulation implements revised out-of-band and spurious emission limits for 2.4 GHz and 5.8 GHz band devices, updated test procedures for 6 GHz Wi-Fi under Article 18, and expands Access Point deployment to permit both indoor and outdoor use in the 5.150 to 5.250 MHz band. Equipment operating in the 5.150-5.250 MHz and 5.250-5.350 MHz bands must comply with new output power and spectral density limits, with stricter constraints when antenna gain exceeds threshold values.
Further analysis of the enforcement mechanism reveals that competent authorities across multiple member states are expected to adopt a phased approach, with initial focus on high-risk product categories before extending surveillance to broader market segments. The transition period, while
