This year's football World Cup is the most connected international sports event this year, even beating the 2010 World Cup, according to research.
The first 10 days of the tournament generated a record-breaking 32 terabytes of data thanks to football fans downloading games to two or three devices at the same time.
"This record at the most-connected World Cup consolidates Oi's global experience as a supplier of telecom at major events, whether sports, entertainment or international conferences," said José Claudio Moreira Gonçalves, COO of World Cup Wi-Fi provider Oi.
The Brazilian telecoms firm was selected by FIFA to supply network equipment, providing Internet connections in 12 stadiums and broadcasting locations, and 700,000 Wi-Fi access points.
Oi estimates that 152,000 devices successfully connected to W-Fi in the 12 stadiums during the first 10 days.
FIFA director of TV, Niclas Ericson, said: "We are seeing good results. Our partners - the government, with the Ministry of Communications, Oi and Telebras, which were involved in the infrastructure - have done their job and we are pleased with the results and grateful for what they have done."
Oi said it has expanded the coverage of its 2G, 3G and 4G mobile telephony networks at different key points across the city.
