Telecommunications in Brazil
Brazil has both modern technologies in the center-south portion, counting with LTE, 3G HSPA, DSL ISDB based Digital TV. Other areas of the country, particularly the North and Northeast regions, lack even basic analog PSTN telephone lines. This is a problem that the government is trying to solve by linking the liberation of new technologies such as WiMax and FTTH) only tied with compromises on extension of the service to less populated regions.

Telephone system

Landline
The Brazilian landline sector is fully open to competition and continues to attract operators. The bulk of the market is divided between three operators: Telefónica, América Móvil, and Oi (controlled by Brazilian investors and Pharol SGPS). Telefónica operates through Telefónica Brasil, which has integrated its landline and mobile services under the brand name Vivo. The América Móvil group in Brazil comprises long distance incumbent Embratel, mobile operator Claro, and cable TV provider Net Serviços. The group has started to integrate its landline and mobile services under the brand name Claro, previously used only for mobile services. Oi offers landline and mobile services under the Oi brand name. GVT was the country's most successful alternative network provider, offering landline services only, until it was acquired by Telefónica in 2015 and integrated into Vivo.

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. 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.

5G services were commercially launched in 2020, initially only in a few cities and in 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 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.

The mobile market is ruled by 3 companies:

Vivo, controlled by the Spanish Telefónica, is the leading mobile and landline carrier in Brazil. In 1Q2023, Vivo served 98 million mobile subscribers.
Claro, controlled by the Mexican América Móvil (owned by Carlos Slim), ranks second in Brazilian mobile market. In 1Q2023, Claro served 82.8 million mobile subscribers.
TIM, controlled by the Italian Telecom Italia is the third largest mobile carrier in Brazil. In 1Q2023, TIM served 61.7 million mobile subscribers.
Oi, which was once Brazil's fourth-largest mobile carrier, filed for judicial reorganization in 2016, selling its mobile division (Oi Móvel) in 2020 to a consortium formed by the three largest operators. In 2022, the sale was approved by the regulatory agency Anatel and Oi's 36.5 million mobile customers were transferred to TIM (40%), Claro (32%) and Vivo (28%).
 Algar Telecom is the largest regional mobile carrier, operating in 4 states. The company's customers have national coverage through roaming agreements with the three major telcos. In 1Q2023, Algar Telecom served 4.5 million mobile subscribers.

International backbones

Submarine cables

Several submarine cables link Brazil to the world:
Americas II cable entered operations in September 2000, connecting Brazil (Fortaleza) to United States.
ATLANTIS-2, with around 12 thousand kilometers in extension, operating since 2000, it connects Brazil (Rio de Janeiro and Natal) to Europe, Africa and South America. This is the only cable that connects South America to Africa and Europe.
EMERGIA – SAM 1 cable connects all three Americas, surrounding it with a total extension of more than 25 thousand kilometers.
GLOBAL CROSSING - SAC Connects all Americas, surrounding them with a total extension of more than 15 thousand kilometers.
GLOBENET/360 NETWORK Another link from North America to South America.
UNISUR Interconnects Brazil, Uruguay and Argentina.

All these cables have a bandwidth from 20 Gbit/s to 80 Gbit/s, and some have a projected final capacity of more than 1 Tbit/s.

Television and radio

Under the Brazilian constitution, television and radio are not treated as forms of telecommunication, in order to avoid creating problems with a series of regulations that reduce and control how international businesses and individuals can participate. Brazil has the second largest media conglomerate in the world in terms of revenue, Grupo Globo.

Internet

The Internet has become quite popular in Brazil, with steadily growing numbers of users as well as increased availability. Brazil holds the  6th spot in number of users worldwide. Many technologies are used to bring broadband Internet to consumers, with DSL and cable being the most common (respectively, about 13 million and 9 million connections), and 3G technologies. 4G technologies were introduced in April 2013 and presently are available in over 90% of the country.
