Overview

On April 23rd, 2020, the Federal Communications Commission (FCC) of the USA approved new rules related to the 6 GHz band, deciding to release 1,200 MHz of spectrum for unlicensed use (5,925 to 7,125 GHz). This includes a protection service established to guard against harmful interference.

Considering that Brazilian regulations on restricted radiation closely align with part 15 of Title 47 of the Electronic Code of Federal Regulations (E-CFR) in the USA, adaptations are necessary for Brazil as detailed in Table I (attached document, Annex I) of the Regulation on Restricted Radiation Radiocommunication Equipment, which was approved by Resolution No. 680 on June 27th, 2017.

Public Consultation

In August 2019, through public consultation no. 47, the extension of the band from 5,460 to 8,025 MHz was requested for use by restricted radiation equipment. This public consultation was approved on May 5th, 2020, through Resolution 726 announced by ANATEL, which takes effect on September 1st, 2020.

Table II (attached document, annex I) includes updated information on radio frequency bands with usage restrictions.

Benefits of the 6 GHz Band

The 6 GHz band offers additional spectrum capacity and provides contiguous blocks of spectrum. This will accommodate 14 additional 80 MHz channels or 7 additional 160 MHz channels, allowing for less congested spectrum compared to legacy Wi-Fi 4 or Wi-Fi 5 devices. Wi-Fi 6E will empower high bandwidth applications that demand faster data throughput with high speeds and low latency.

Important Updates

Resolution 726 has extended the range from 57 GHz to 71 GHz for 802.11ad technology use and expanded the frequency range from 76 GHz to 81 GHz for vehicular radars.
