Is HD voice strictly restricted to 3G (UMTS) networks?

November 25, 2013

No. HD voice can also be supported by GSM, UMTS, LTE and CDMA2k or fixed networks. Today, the GSMA offers the logo use for GSM, UMTS, LTE and CDMA2k, networks and mobile and fixed phones. In addition, the GSMA has collaborated with the DECT Forum to provide terminal requirements for DECT handsets. See: www.gsma.com/hd-voice.
