Editing Telecommunications in Brazil (section)

===Mobile===
The history of mobile telephony in Brazil began on 30 December 1990, when the Cellular Mobile System began operating in the city of Rio de Janeiro, with a capacity for 10,000 terminals. At that time, according to Anatel (the national telecommunications agency), there were 667 devices in the country. The number of devices rose to 6,700 in the next year, to 30,000 in 1992.

In November 2007 3G services were launched, and increased rapidly to almost 90% of the population in 2012 and the agreements signed as part of the auction specify a 3G coverage obligation of 100% of population by 2019.

After the auction that took place in June 2012, LTE tests were undertaken in several cities, tourist locations and international conference venues.<ref name="abril">{{cite web|url=http://exame.abril.com.br/tecnologia/noticias/claro-testa-4g-em-campos-do-jordao-sp |title=Claro testa 4G em Campos do Jordão-SP |date= 5 September 2012 |publisher=exame.abril.com.br|access-date=2 September 2015}}</ref> The first LTE-compatible devices became available in the local market and LTE services was commercially launched in 2013. Under the 4G licence terms, operators were required to have commercial networks in all twelve state capitals which are acting as host cities for the [[2014 FIFA World Cup]].<ref>{{cite web| url =http://www.telegeography.com/products/commsupdate/articles/2014/01/07/all-four-4g-licensees-confirmed-as-having-met-end-2013-coverage-deadline/| title =Rostelecom All four 4G licensees confirmed as having met end-2013 coverage deadline| work =Telegrography|date=7 January 2014| access-date = 15 February 2014}}</ref>

5G services were commercially launched in 2020, initially only in a few cities and in [[5G_NR#Dynamic_spectrum_sharing|DSS]] mode. In 2021, the regulatory agency [[Anatel]] carried out the auction of the 3.5 GHz spectrum, which allowed the operation of 5G in standalone mode (SA). In July 2022, Brasília was the first city to have [[5G_NR#Standalone_mode|5G NR SA]] made available, with all state capitals being served by the three major carriers by the end of 2022. By July 2023, 753 cities had 5G coverage, which accounts for 46% of the country's population.<ref>{{cite web| url =https://www.gov.br/mcom/pt-br/noticias/2023/julho/5g-completa-um-ano-com-cobertura-disponivel-para-mais-de-140-milhoes-de-brasileiros| title =5G completa um ano com cobertura disponível para mais de 140 milhões de brasileiros| work =Ministério das Comunicações|date=6 July 2023| access-date = 24 July 2023}}</ref>
