Sprint has made some upgrades to their LTE network that will benefit current 4G subscribers as well as complement their work towards eventually launching 5G. The implementation of “massive MIMO” technology along with the backbone of the LTE Advanced network will allow the company to be on the right track for 5G, said Sprint CTO John Saw. “It will be faster, simply because we’re killing two birds with one stone,” Saw said about the massive MIMO deployment.
