Ericsson has successfully completed the first CDMA wideband High
Definition (HD) voice call.
CDMA HD voice delivers speech in a wider spectral range of 50Hz to 7000Hz,
which
increases voice quality and intelligibility, and decreases listening fatigue,
even
in environments with high background noise.
Surya Bommakanti, Vice President,
Product
Area Core, BU CDMA Mobile Systems, Ericsson stated, "This is the starting point of
a
voice quality revolution that will significantly enhance CDMA networks as
we
know them today."
The CDMA HD voice cal was made using the Enhanced Variable Rate Codec
Narrowband-
Wideband (EVRC-NW) codec.
The Ericsson CDMA development team, in collaboration with Qualcomm
Incorporated, successfully completed HD voice
calls
in a lab environment on a CDMA voice network.
CDMA carriers in the U.S. who could use the service are Verizon and
Sprint. Maybe Verizon ads will say, "Can you here be better, now?"
