Ericsson completed a CDMA wideband High Definition (HD) voice call using the Enhanced Variable Rate Codec Narrowband-Wideband (EVRC-NW) codec. The lab demonstration marks a first first for the CDMA industry.


CDMA HD voice delivers speech in a wider spectral range of 50Hz to 7000Hz.


"We have demonstrated the first high-definition CDMA voice call in the world over an Ericsson network utilizing the new EVRC-NW 3GPP2 standard codec and ensuring interoperability with existing functionality while easing the rollout of future wideband services." says Surya Bommakanti, Vice President, Product Area Core, BU CDMA Mobile Systems, Ericsson. "This is the starting point of a voice quality revolution that will significantly enhance CDMA networks as we know them today."


The Ericsson CDMA development team collaborated with Qualcomm for the HD voice over CDMA demonstration.
