Sprint doesn't have much time to meet its goals and get its 4G LTE network up and running by mid-2012. The Now Network is definitely getting closer, though, and just gave PCMag the chance to test its fledgling LTE in Atlanta. Average speeds on the downlink sit squarely in between AT&T and Verizon, at 9 to 13Mbps, despite Sprint having to use 5MHz channels half as large as what AT&T can muster in some cities.
