Press reports out of the Sprint HTC EVO 4G LTE event say the company will first deliver HD voice over its enhanced/advanced 3G network over CDMA 1X Advanced technology using Qualcomm’s EVRC-NW’s codec – not via LTE. Ain’t that a kick in the pants?
Last year, Sprint indicated it would be upgrading its 3G network along with rolling out LTE as a part of its Network Vision plan and executives hinted they would have the “tools” to deploy HD voice over CDMA as well as doing VoLTE.
Sprint held a late afternoon press event to introduce the HTC EVO 4G LTE, with the announcement/emphasize of HD voice as a bit of a surprise. The company said HD voice service will appear in “Late 2012” as a part of a nationwide rollout, with more phones supporting the technology rolled out during the course of the year.
A report at AnandTech, says the HTC EVO 4G LTE includes noise cancellation utilizing dual microphones on the phone – a technique that’s been used a lot both on the AMR-WB side of the world and on high-end smart phones with narrowband calls.
(And THANK YOU Sprint for not using the crappy phrase “HD audio”).
