AT&T is preparing to start routing voice calls over its LTE network, making way for the introduction of HD voice. The news was announced at the VentureBeat Mobile Summit in California by AT&T senior VP Kris Rinne.
“HD Voice is part of our voice over LTE strategy,” Rinne was quoted as saying, adding past issues with call failure and other technical issues have been resolved. “I think we’ve taken that off the table in terms of a competitive challenge.”
But the technology won’t work through AT&T alone: Devices on both ends of the call must be equipped to handle HD voice. Sprint launched HD voice on its network last year and T-Mobile has promised its iPhone5 will soon be able to utilize the technology.
