At the end of the fourth quarter of 2011, the worldwide Long Term Evolution subscriber base nearly doubled quarter over quarter to reach 12 million subscribers worldwide, according to Maravedis-Rethink. The quarter over quarter subscriber increase for LTE and WiMAX was 92 percent and 14 percent, respectively, over that reported at the end of the third quarter of 2011, according to Miravedis-Rethink.
At the end of 2011, 54 operators worldwide had launched LTE commercially, 19 during the quarter alone. An additional 224 major mobile operators had committed to launching the technology in the future, 193 of those with FDD-LTE and 31 with TD-LTE. Maravedis-Rethink anticipates that 469 million LTE subscribers will be active by 2016 of which 25 percent, or 118 million, will be TD-LTE users and the rest (75 percent, or 350 million) will be FDD-LTE.
