Sprint just started building out its LTE network, but being the eager beavers that they are, the folks in Overland Park are already talking about taking the Now Network to the next level. Iyad Tarazi, Sprint's VP of network development and engineering, said that Sprint will be rolling out an LTE-Advanced network in the first half of 2013. (As a brief refresher, LTE-Advanced is a true 4G technology that can make regular LTE speeds look positively pedestrian in comparison.) Tarazi added that we would see 12 LTE devices in 2012 and that over 250 million people will have access to Sprint-flavored LTE by the end of 2013 -- with voice over LTE service coming in the first quarter of that year. For those (hundreds?) of you worried about the fate of of WiMAX, well, don't. Apparently, the out-of-favor 4G network will continue to be supported for several more years due to Sprint's agreement with Clearwire. So, it appears Sprint's really making a run at Verizon's LTE hegemony. Good luck Mr. Hesse, you're probably going to need it.
