Major Updates to RF Requirements and Test Procedures in Brazil
On October 8, 2025, ANATEL released Act No. 14158, introducing extensive updates to Brazil’s RF technical requirements (Act 14448/2017) and test procedures (Act 237/2022). The new rules become mandatory on April 6, 2026. Until then, manufacturers may continue using the current framework—but early alignment with the updated requirements is strongly recommended, as laboratories transition to the new methodology.
Key Regulatory Updates
New Definition for Vehicle Radar Systems
ANATEL has added a formal definition for “vehicle radar system,” covering radars installed on land and aquatic transport platforms (cars, trucks, motorcycles, trains, tractors, boats, ships). This clarifies the scope of radar-focused compliance evaluations.
Wireless Audio Systems (54–608 MHz)
New criteria define limits and test conditions for digital multichannel microphones and professional audio equipment, referencing ETSI EN 300 422-1. This provides clearer compliance pathways for PMSE and wireless audio devices marketed in Brazil.
Radar Rules for 76–81 GHz & Airport Use
ANATEL now explicitly permits radar operation in airport environments and on-ground aircraft, while maintaining existing limits for vehicle radars in the 76–81 GHz band.
New 116–246 GHz Frequency Section
A new section defines technical limits for mmWave/EHF systems operating between 116–246 GHz, including:
– EIRP limits up to 43 dBm (82–85 dBm for fixed outdoor P2P links)
– RBW = 100 kHz for measurements
– Spurious emission ceiling of ≤ 90 pW/cm² above 40 GHz
– Prohibition of use on aircraft or satellites
This opens opportunities for high-capacity backhaul and advanced fixed-link deployments above 100 GHz.
Major Revisions to 5 GHz Wi-Fi Bands
ANATEL has restructured 5 GHz technical limits and introduced new sub-items covering APs, client devices, and fixed P2P links. Key changes include:
– Conducted power limits replacing EIRP in key sections
– Bandwidth-dependent formulas (11 dBm + 10 log B) for 5.250–5.350 MHz and 5.470–5.725 MHz
– Vertical radiation restrictions for outdoor APs in 5.150–5.250 MHz
– Revised spurious emission rules (20 dB/30 dB attenuation depending on method)
– Increased TPC dynamic range requirement (6 dB minimum)
Updated Rules for 57–71 GHz Devices
Expanded provisions now address the full 57–71 GHz range with modernized limits for Field Disturbance Sensors and other mmWave devices. Highlights include:
– FDS limits: ≤ –10 dBm conducted / ≤ 10 dBm peak EIRP
– Alternative high-power allowances with duty-cycle constraints
– Mean EIRP up to 40 dBm for other 60 GHz systems
– Strict exposure limits above 40 GHz and updated aircraft restrictions
These changes bring Brazil’s 60–70 GHz rules closer to international standards.
Updated Test Procedures for 6 GHz Wi-Fi (Wi-Fi 6E/7)
Act 14158 revises Articles 15–15.3 of Act 237/2022 to align with FCC test principles, including references to:
– FCC KDB 789033 D02 (6 GHz methodology)
– FCC KDB 987594 D02 (CBP validation)
The V2X band (5.850–5.925 GHz) remains restricted, and measurement bandwidths are standardized across both Acts.
These extensive revisions mark one of ANATEL’s most significant updates in recent years and will impact Wi-Fi, radar, mmWave, audio, and sensing technologies across the Brazilian market.
