Ericsson 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.
Ericsson leads the industry in introducing new technologies with superior voice quality. Ericsson consumer research shows that voice quality provides a key differentiator between operator networks by improving subscriber retention and increasing mobile usage.
