Telstra has unveiled the mobile phone equivalent of switching from Standard Definition to High Definition Television with the launch of High Definition Voice calling across its entire Next G® mobile network.
Mike Wright, Executive Director, Telstra Networks & Access Technologies said “The difference between a standard and HD call is the voice equivalent of comparing a VHS with a blue-ray DVD, HD Voice calling sounds like you’re talking face to face, even if you are hundreds or thousands of kilometres apart.”
HD Voice is made possible using state of the art technology known as Wideband Adaptive Multi-Rate coding (WB-AMR). The wider dynamic range means over twice the range of voice frequencies are transmitted allowing customers to hear the full range of a person’s voice and makes it much clearer to distinguish between similar sounds like ‘S’ and ‘F’.
“HD-voice calls will require the caller and receiver to be using compatible handsets on the Telstra Next G® mobile network for the full benefits of the technology. We expect our customers will really value HD Voice as another distinguishing feature of the Next G® mobile network,” said Mr Wright.
