Almost a month ago, we shared with you an industry rumor about Sprint's, "Project Leapfrog", in which Sprint was already laying the foundation toward changing over to LTE, away from WiMAX. New industry intel seems to suggest that "Project Leapfrog" is coming even closer to reality, and that an official announcement may be forthcoming fairly soon. Here's a quote from the PhoneArena article,
"During a press tour of the facility that he oversees, Geoff Martin, (manager of operations at the carrier's M2M Collaboration Centre in Sillicon Valley), commented on Sprint's alleged switch to LTE stating that there was a “high likelihood” of the technology being adopted by the carrier “in one flavor or another” and that “announcements will be made soon.”
As always, we will keep you informed as more details emerge.
