Event will be held in Belo Horizonte, Brasilia, Fortaleza, Recife, Salvador and Rio.
Speed test assessed to watch videos, post pictures and download game.
Little more than ten months after the federal government to auction the frequency of 2.5 gigahertz (GHz), began operating in the country technology of mobile broadband fourth generation - 4G. The G1 has tested the service in six capital cities that will host the Confederations Cup in June 2013: Belo Horizonte, Brasilia, Fortaleza, Recife, Rio de Janeiro and Salvador.
According to the schedule of the National Telecommunications Agency (Anatel), the installation of 4G in all host cities of the competition should be done by Tuesday (30) by companies. The evaluation of G1 was held between April 30 and 26, only with the 4G network service course.
Companies TIM, Vivo and Hi had not tested the service because they have commercially launched the network in time. TIM and Vivo presented their plans on Tuesday (30), while the Hi 4G launched operation in Rio de Janeiro on the 25th, with pre-sale for the other five cities in the first half of May. All operators, however, are within the deadline set by Anatel.
In some locations such as Copacabana, in Rio de Janeiro, the speed of 4G was five times the 3G network while performing the same activity. The test sought to measure the performance differences of download speeds between 3G and 4G connections. For this, we used the measurement application SpeedTeste.
To test in practice as the fourth generation technology would react, were stipulated other four activities: 1) post a one-minute video on YouTube and watch a clip of the same duration on the site, 2) publish a photo of 2 Megabytes (MB) the social network Facebook, 3) send an email with a picture attached of the same size; 4) download the game "Dead Trigger", which has 164 MB.
The evaluation was performed in places where foot traffic and network utilization should be higher during the competition, such as airports, stadiums, tourist areas, hotels and regions in the road.
Check out the results in each city:
Belo Horizonte
The evaluation of 4G internet taken by G1 showed that the new connection is not working on important points such as the airport and the hotel zone, located in the city of Confines Metropolitan Region. At the Central Market, the 4G network is available at speeds of 12.3 Mbps for download, much higher than the 0.936 Mbps registered with 3G. The YouTube video took 5 minutes and 17 seconds to be posted on the legume, with 4G, while with the third generation only 14% of the content was loaded after 15 minutes of waiting (see results).
Brasilia
In the federal capital, the performance of 4G was nine times higher than that recorded for the 3G network. At the National Stadium, the game took 3 minutes and 18 seconds to be downloaded with 4G, against 20 minutes 56 seconds with the 3G connection. The proposal also provided the use of YouTube, which did not happen due to problems in the devices used in the evaluation. The G1 failed to capture the signal of 4G in the area of domestic arrivals on the ground floor, or in front of boarding gates national, on the first floor of the Airport JK (see results).
Fortress
The time to post the photo on Facebook was about 15 times lower when the 4G network was used, 37 seconds versus 10 minutes 30 seconds with 3G connection, when the test took place on Avenida Beira Mar. The situation was similar for sending an e-mail with attached images. Fortaleza airport was the point of the capital where the 4G connection showed greater speed (see results).
Recife
The e-mail with photo attached took up to 12 minutes to be sent with the 3G network in Recife, against about 30 seconds using the new network. The test done in the city showed that, for posting a video on YouTube, the delay with 3G was 13 minutes, well above the time between 6 and 8 minutes when using broadband fourth generation. According to the course, access to 4G is only available in prime neighborhoods of Recife (see results).
Rio de Janeiro
In the speed test, the G1 found that the ability to download the 4G to be five times that of the 3G connection. We visited some of the most visited tourist attractions such as Copacabana beach, Christ the Redeemer and Sugar Loaf. The video on YouTube took 56/2 to be posted when 4G was used, but up to 7 minutes and 3 seconds with the 3G network. Coverage of new mobile broadband still has instability in some parts of the river where the 4G is running as on Ipanema beach (see results).
Salvador
Of the four sites tested by G1 in Salvador, only the airport did not have the technology available. Unable to access the 4G network in the Arena Fonte Nova stadium in the Confederations Cup, the Lacerda Elevator and the region's hotel district of Red River. According to the course, the 4G is available in 36 districts. Near the stadium, it took up to 13 minutes and 30 seconds post the video on YouTube (see results).
