Brazil’s National Telecommunications Agency (ANATEL) has enacted Act No. 14158, introducing sweeping changes to the technical and testing requirements for restricted-radiation radiocommunication equipment. The regulation, published on October 8, 2025, and mandatory from April 6, 2026, revises the foundational conformity and testing instruments (Acts 14448/2017 and 237/2022). It imposes stricter limits on 5 GHz Wi-Fi devices, vehicle and airport radar, mmWave systems, and professional wireless audio equipment.

For Wi-Fi hardware in the 5,150–5,250 MHz band, the act sets new conducted output power and spectral density limits, introduces antenna gain reduction rules, and restricts outdoor EIRP at high elevation angles. The upper 5 GHz sub-bands also see tighter power and spectral density caps. Dynamic frequency selection (DFS) and transmit power control (TPC) requirements are reinforced, and user access to region or compliance settings is further constrained.

The act expands the regulatory scope for mmWave devices, allowing field-disturbance sensors in portable consumer electronics under defined limits and establishing new criteria for equipment up to 123 GHz. Automotive and airport radar systems receive updated definitions and operational conditions. Professional wireless audio (PMSE) systems must now comply with ETSI EN 300 422-1 V2.2.1 and new digital multichannel requirements.

All new and ongoing certifications must comply with the revised parameters. Local testing at ANATEL-accredited labs remains mandatory, with foreign reports only supporting the technical file. Manufacturers and importers must re-verify affected designs, update firmware controls, and ensure technical documentation reflects the new rules.

This is a High Impact regulatory change.

Key reasons for high impact:

• The act is already in force and mandatory for all new and ongoing certifications as of April 6, 2026.
• It introduces new, stricter RF limits and technical requirements for a wide range of wireless products, including Wi-Fi, radar, mmWave, and professional audio devices.
• Local testing at ANATEL-accredited labs is required, and foreign test reports cannot substitute for in-country testing.
• Firmware and regional controls must be updated to prevent non-compliance.
• The regulation affects both new approvals and ongoing maintenance of certificates.

Who is affected?

Manufacturers, importers, and regulatory affairs teams placing wireless products on the Brazilian market.
Certification bodies (OCDs) and ANATEL-accredited laboratories.
Sectors including consumer electronics, automotive, professional audio, and airport operations.

Conclusion:

Immediate action is required for compliance. Non-conforming products risk market exclusion, and all stakeholders must update technical files, firmware, and testing protocols to align with the new requirements.
