Ericsson Claims First HD CDMA Voice Call

Mar 17, 2011, 9:42 AM by Eric M. Zeman

Ericsson today says it successfully completed the world's first CDMA wideband High Definition (HD) voice call. In order to make the call, Ericsson used the Enhanced Variable Rate Codec Narrowband-Wideband (EVRC-NW) codec in a lab with equipment from Qualcomm running on a CDMA network. Ericsson says that CDMA HD voice delivers speech in a wider spectral range (50Hz to 7000Hz). This increases voice quality and decreases listening fatigue. Ericsson didn't say if or when such capabilities will become available to handsets.

Cool! :)

Hopefully this can be implemented soon! I have an Incredible and have found voice quality on Verizon is kind of muddy and muffled sounding. An improvement there would be most welcome!

I'm sure a lot of us were hoping for high definition audio someday. But i am sure carriers will find a way to charge a premium for the experience....

Once IMS is common place across carriers....probably 5-10 years out before its end to end, things...
