5G signal now authorized in all Brazilian municipalities
Telephone operators are now free to deploy 5G technology in every municipality across the country. This development became possible after interference issues were fully resolved, enabling the activation of the signal in all 5,570 Brazilian municipalities.
On November 26, the National Telecommunications Agency (Anatel) and the Band Management Entity (EAF) announced the completion of the “cleaning” process for the 3.5 gigahertz (GHz) frequency band designated for 5G. However, the signal was officially released on Monday (Dec. 2).
Before 5G's arrival in Brazil, the 3.5 GHz frequency band was primarily used for broadcasting and free-to-air satellite television services, particularly via satellite dishes operating in Band C. This technology functioned within the 3.7 GHz to 6.4 GHz range, which is very close to the frequency allocated for 5G.
Over the last few years, Anatel has focused on two key initiatives: migrating from Band C and eliminating interference near the 3.5 GHz band. As part of the migration effort, 1,482 professional satellite stations (FSS) were relocated from the Extended C Band. These stations were used by radio and TV broadcasters, distance learning institutions, and even the Air Force. The migration process was completed in March of this year, two years ahead of schedule.
The second phase involved clearing the frequency by installing filters on satellite dishes to reduce interference from towers on mobile devices. Additionally, approximately 4.3 million free conversion kits were distributed to families enrolled in federal social programs who rely on traditional satellite dishes for access to free-to-air TV signals.
With the frequency band cleared, operators are now authorized to install 5G technology in any city nationwide. However, the auction guidelines require full activation of the signal in all municipalities by 2029.
