Increasingly, access the Internet from mobile connections. In addition to smartphones like the iPhone 3G and its subsequent imitators, the netbooks provide greater mobility with usability and functionality.
The emergence of netbooks very similar to conventional computers in terms of functionality but with a smaller weight and size are increasing the demand for mobile broadband connectivity.
A few years ago, the connections of mobile GSM (2G) provided a very limited connectivity (9.6 kbps), which made impossible the simple act of sending something a little heavier than an SMS. The future seemed to be the next generation of 3G or UMTS mobile communications (up to 2 Mbps). Some acronyms become cursed because of the high costs incurred by the telecoms to get one of these licenses in countries like Germany and the UK.
While introducing these networks, a significant improvement was achieved with GPRS or 2.5G, and allowing the connection speeds similar to fixed ISDN, ranging between 56 and 114 kbps.
At present, some operators already offer superior technologies such as UMTS or HSDPA 3.5 G, which allows speeds of up to 14 Mbps
