ANATEL Publishes New Technical Requirements – Act No. 14158/2025

Effective from April 6, 2026

ANATEL has published Act No. 14158/2025, introducing critical updates to Brazil’s technical requirements for radio frequency devices. These updates affect multiple industries, from automotive radar systems to Wi-Fi devices. The new requirements, which will become mandatory on April 6, 2026, align with international standards and address emerging technologies.

Key Updates

Wireless Audio Systems (microphones, IEMs, PMSE) – A new item (20.2) defines power limits and test conditions for digital multichannel wireless audio systems, referencing ETSI EN 300 422-1.

Impact: Provides harmonized criteria for professional wireless audio systems operating between 54-608 MHz.

________________________________________

Radar Systems (76-81 GHz and above) – New provisions regulate the use of vehicle radars and airport-related radars:

• Operation of radars in airport areas and on-ground aircraft is now explicitly allowed
• Vehicle radars (76-81 GHz) remain covered by their specific technical limits.

________________________________________

New Frequency Section: 116 GHz to 246 GHz (Section 25) – A new Section 25 has been created for systems operating between 116-123 GHz, 174.8-182 GHz, 185-190 GHz, and 244-246 GHz.

• Defines EIRP limits (40 dBm average / 43 dBm peak; up to 82 / 85 dBm for fixed outdoor P2P links)
• Establishes measurement bandwidth (RBW = 100 kHz) and spurious limits (≤ 90 pW/cm²) above 40 GHz
• Prohibits use of these bands on aircraft or satellites.

Impact: Opens regulatory access for high capacity backhaul and fixed mmWave/EHF applications above 100 GHz, with clear emission and safety boundaries.
