Sprint announced today it will be switching 4G technologies from WiMax to LTE. The LTE network should go live in mid 2012 and and have a "full rollout" by 2013. Sprint eventually hopes to double current amount of 4G customers with its LTE rollout.
Joining the LTE ranks puts Sprint in the same technology corner as AT&T and Verizon, with only T-Mobile still clinging to HSPA+. Sprint's slice of the LTE airways will be the 800 and 1900Mhz spectrum and, pending the FCC's blessing, 1600MHz.
