Codec promises improved voice quality

Ericsson has announced that it has successfully demonstrated its "HD voice" technology on a CDMA network. The new technology, which was first previewed using an HSPA network, promises to bring significant improvements to voice quality and intelligibility, while expanding the spectral range to reach from 50Hz to 7kHz.

The system relies on the company's Enhanced Variable Rate Codec Narrowband-Wideband (EVRC-NW) code, which appears to work on principles similar to that of other "HD" voice technology utilized by companies such as Orange.

Ericsson's initial preview was limited to tests within a lab. The company is currently previewing the technology for potential customers, though it remains unclear if or when HD voice will be brought to CDMA networks.
