Brazil: ANATEL’s Public Consultation on WiFi 6 GHz Frequency Band Update

On April 28th, ANATEL initiated Public Consultation No. 29/2024 which focused on limiting the operational frequency band of WiFi 6 GHz in Brazil.

Proposed Frequency Band Changes

The revision of Item 11.7 of Act 14448 outlines the technical requirements for assessing the conformity of restricted radiation equipment. The proposed updates seek to restrict the WiFi 6 GHz band (impacting WiFi 6E and WiFi 7) from the current range of 5925-7125 MHz to a narrower band of 5925-6425 MHz. The purpose of this change is to allocate the 6425-7125 MHz range for future International Mobile Telecommunication (IMT) systems, reducing spectrum interference.
