This week Sprint has been putting out details on its fast-moving LTE rollout at 4G World. The company expects to deploy Voice over LTE (VoLTE) in early 2013 and add voice call continuity by the end of 2013, to move calls between CDMA, LTE, and WiFi.
According to one report from Good and Evo, Sprint will intro VoLTE in the first quarter of 2013, which would “allow for” services like HD voice and simultaneous voice and data usage.
But Sprint hasn’t done more than make brief references to HD voice. Given its history in trying to make up its mind with LTE, this shouldn’t be surprising.
Verizon Wireless is providing HD voice via the AMR-WB codec in its VoLTE rollout sometime in 2012 and demonstrated the technology at Mobile World Congress this spring. AT&T plans to roll out its VoLTE offering in 2013, but also has not said if it will support AMR-WB as the native codec for LTE.
