Why DO-Advanced?Ericsson predicts Mobile Data Traffic to grow 10-fold by 2016Nov7, 2011 http://www.ericsson.com/news/1561267The report is based on measurements the company recorded over several years in live networks covering all regions of the world. According to the report, mobile broadband subscriptions will reach almost 5 billion in 2016, up from the expected 900 million by the end of 2011.That would represent 60 percent year-on-year growth, at the same time as the data consumed by smartphone users is surging. Total smartphone traffic is expected to triple during 2011.
