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.
Act No. 14158 modifies Annex I of Act No. 14448 (2017) and updates Act No. 237 (2022) concerning conformity assessment test procedures for restricted radiation radio communication equipment. The regulation adopts several FCC testing standards, including procedures from FCC KDB 789033 and KDB 987594, to harmonize with international test methodologies.
Article 8 (Item 17) introduces revised requirements for devices operating in the 57 to 71 GHz range, relevant to 60 GHz wireless systems. The regulation establishes differentiated requirements for field disturbance sensors and other devices, with variable EIRP limits, pulsed operation standards, and duty cycle restrictions depending on bandwidth and use case.
For wireless audio systems, the regulation introduces new item 20.2 defining power limits and test conditions for digital multichannel wireless audio systems, referencing ETSI EN 300 422-1 V2.2.1. This sets new transmission power limits for digital multichannel systems including wireless microphones and in-ear monitors.
The regulation particularly affects manufacturers of 5G devices, Wi-Fi 6/6E products, and high-frequency wireless systems. Vehicle radar systems now encompass radars installed in land or water vehicles, including trains, ships, and tractors, with broader definitions harmonized with prior Acts 4776/2020 and 14448/2017.
A critical change affects power measurement methodology: the new regulation uses conducted power rather than total EIRP for specific device categories. This shift directly impacts laboratory test setups and requires coordination with test laboratories before any submission to ensure proper test plan alignment.
For broadband wireless access systems operating in the 5.470-5.725 MHz band, new rules define maximum conducted output power, spectral density, and requirements for spurious emissions. Transmission Power Control (TPC) becomes mandatory for broadband access systems unless a lower EIRP cap is respected.
Equipment operating in the 5.925-7.125 MHz band must undergo contention-based protocol testing to ensure fair spectrum sharing. The regulation includes specific guidance for measuring emissions at elevation angles and handling emissions at band edges, aligning with FCC measurement procedures.
For the 57-71 GHz band, the regulation establishes specific requirements for field disturbance sensors with variable EIRP limits based on bandwidth and operational parameters. Devices in this frequency range must comply with pulsed operation standards and duty cycle restrictions depending on their specific use case.
The regulation maintains existing certification pathways while updating technical specifications. Testing laboratories must update their procedures to reflect the new measurement methodologies, particularly the shift from EIRP to conducted power measurements for affected device categories.
Act No. 14158 became effective October 1, 2025, with mandatory compliance beginning April 6, 2026. Manufacturers with products pending Brazilian certification as of April 2026 must confirm with their testing laboratories that test plans have been updated to reflect the new requirements.
Existing certifications remain valid under transitional provisions, but new applications submitted after April 6, 2026, must comply with the updated technical requirements and test procedures. The regulation does not specify a grace period for products already in the certification pipeline, making early coordination with test laboratories essential.
For 5G devices operating in millimeter-wave frequencies, the new Section 25 requirements apply to the 116-246 GHz range. These devices must demonstrate compliance with average and peak EIRP limits specific to their operational frequency bands. The regulation prohibits operation on aircraft or satellites for devices in these frequency ranges.
Devices operating in the 57-71 GHz range, commonly used for 5G backhaul and short-range communications, must comply with Article 8 (Item 17) requirements. This includes variable EIRP limits, pulsed operation standards, and duty cycle restrictions based on bandwidth and application.
Manufacturers should immediately verify their current certification status and identify products requiring updates under Act No. 14158. Contact testing laboratories to confirm test plan updates, particularly for devices affected by the conducted power measurement methodology change.
For Wi-Fi 6E and Wi-Fi 7 products, review compliance with updated emission limits for 2.4 GHz and 5.8 GHz bands. Verify that 6 GHz Wi-Fi products meet the revised Article 18 test procedures and confirm outdoor deployment capabilities for Access Points in the 5.150-5.250 MHz band.
Products operating in the newly covered 116-246 GHz frequency ranges require complete certification under Section 25 requirements. Ensure EIRP limits compliance and verify that devices are not intended for aircraft or satellite use, which remains prohibited.
For automotive and industrial radar systems, confirm that expanded vehicle radar definitions apply to your products and verify compliance with harmonized requirements from Acts 4776/2020 and 14448/2017.
Establish testing laboratory relationships early, as the shift to conducted power measurements may require different test setups and potentially longer testing timelines. Current laboratory queue times and capacity should be assessed for products requiring certification under the new requirements.
