Sprint announced at its Strategy Update meeting on Friday that it has adjusted its 4G rollout plans in order to deploy the carrier’s new network more rapidly. The carrier will also convert to a single-network architecture, moving away from CDMA and WiMAX as it rolls out its LTE network. Sprint had initially announced a 3-5 year plan for the rollout, and on Friday network operations head Steve Elfman confirmed that Sprint’s 4G LTE network rollout will be largely complete by the end of 2013. Sprint’s 4G LTE network will launch in initial markets in mid-2012, and the carrier is working with Qualcomm to ensure an assortment of devices are available at launch. Sprint also confirmed that it will continue to sell 4G WiMAX devices through 2012.
