Tests conducted by Brazilian daily Folha de Sao Paulo of the 4G connection in 21 districts of the city of Sao Paulo have rated the network "frustrating" due to gaps in coverage and varying speeds. The upload and download rates in some places of the city were almost equal to those of 3G. However, when the signal worked properly, the connection proved to be very fast. All the operators admit that there is room for improvement in coverage. Vivo blames the restrictive legislation of the municipality and says it hinders the installation of new antennas. TIM said it is offering complementary solutions, such as 3G and Wi-Fi, while Claro claims it covers 80 percent of Sao Paulo, but there are still spaces to be filled. Oi still does not provide a 4G signal in the city.
