5G antenna tower silhouette against the deep blue twilight sky, symbolizing the new era of mobile connectivity in Brazil.

About this subject

5G antenna towers form the backbone of the fifth generation of mobile networks, which began deployment in Brazil in 2021. Unlike previous generations, 5G operates on three frequency bands: low (700 MHz), mid (2.3 GHz and 3.5 GHz), and high (26 GHz, known as millimeter waves). Towers need to be more numerous and closer together, especially for the 3.5 GHz band, which offers higher speeds but shorter range. In Brazil, the National Telecommunications Agency (Anatel) auctioned the frequencies in 2021, and since then operators such as Vivo, Claro, and TIM have been installing thousands of new antennas across the country. The tower's silhouette against the twilight sky evokes the ubiquity of technology, which is already present in over 5,000 Brazilian municipalities. 5G goes beyond faster smartphone speeds; it enables applications such as autonomous cars, remote surgery, and smart cities, thanks to ultra-low latency (below 1 ms) and the ability to connect up to 1 million devices per km². Network expansion faces challenges such as the need for fiber optic backhaul and resistance from some communities to new tower installations. Nevertheless, Brazil already ranks among the countries with the largest 5G coverage in Latin America, with a forecast to reach 90% of the urban population by 2026.

Frequently Asked Questions

What differentiates 5G from previous mobile network generations?

5G offers download speeds up to 20 Gbps, latency below 1 ms, and the ability to connect up to 1 million devices per km², enabling applications such as remote surgery and smart cities.

How many 5G antennas are there in Brazil currently?

As of 2025, Brazil has over 40,000 5G antennas installed, covering more than 5,000 municipalities, according to data from Anatel and operators.

Does installing 5G towers pose health risks?

No. The World Health Organization (WHO) and Anatel state that emissions from 5G antennas are within internationally established safe limits, with no proven health risks.
