Worldwide subscribers to LTE at the end of 2011 will number a projected 11.6 million, up from 300,000 in 2010, IHS iSuppli predicts.
Another round of growth is anticipated for 2012 when the technology increases its subscriber rolls by 442 percent to hit 62.8 million.
Growth in the three years after 2012 will slow down somewhat but remain robust, at an estimated 214 percent in 2013, 105 percent in 2014 and 84 percent in 2015, the firm predicts.
But forecasts have edged up over the last couple of years. In 2009 Pyramid Research estimated LTE usage in 2015 at about 375 million still would trail that of older mobile technologies, at 3.8 billion 2G subscribers and 2.8 billion 3G subscribers, Pyramid Research has predicted.
