The acronym 3G is the third generation mobile technology, with a capacity of up to 2 Mb/s (megabits per second). The “H”, improvement of 3G and better known as 3G+, corresponds to HSPA (High Speed Packet Access) and reaches 14 Mb/s. While the H+ (or evolved HPSA), goes up to 168 Mb/s. Finally, there is 4G, which reaches 200 Mb/s – in Brazil, the average speed is 21 Mb/s.
