Ericsson Claims First HD CDMA Voice Call
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.
