Ericsson said it has successfully completed a CDMA wideband High Definition (HD) voice call using the Enhanced Variable Rate Codec Narrowband-Wideband (EVRC-NW) codec, demonstrating a technical first for the CDMA industry. CDMA HD voice delivers speech in a wider spectral range of 50Hz to 7000Hz, which increases voice quality, intelligibility and decreases listening fatigue, even in environments with high background noise.

"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 in collaboration with Qualcomm Incorporated has demonstrated this feature in a lab environment on a CDMA voice network.
