Just one example - according to Cisco, mobile data traffic in 2010 "was three times as large as all the world's combined Internet traffic in 2000", and it's bound to grow - calculations claim that in 2015 we will witness a 26 times increase compared to what we experience at the moment. Moreover, year-on-year growth was 2.6 times between 2009 and 2010.
The future data traffic increase is mainly attributed to video calling and sending of video clips.
Furthermore, this beautiful word - 4G - will play bigger and bigger role as time passes - at the moment, the average wireless speed on a mobile handset worldwide is 200Kbps, and that speed is expected to become 2.2Mbps with the mass 4G deployment.
