Mobile Voice Quality To Improve As HD Voice Rollout Begins

Sprint this week became the first U.S. carrier to announce the availability of a phone with radically better voice quality, known as high-definition voice.

The HTC EVO 4G LTE (Long Term Evolution

The HTC EVO 4G LTE (Long Term Evolution, latest standard in the mobile network technology) will be available in the second quarter for $199.99, the company said. But, it could be many more quarters earlier the rollout of nationwide 4G LTE (Long Term Evolution, latest standard in the mobile network technology) networks is complete and large numbers of people benefit from better sound quality.

For anyone who has struggled to understand the person at the other end of a mobile phone conversation, high-definition voice could transform their relatiionship with their wireless carrier by providing much clearer, more natural sound. Backround noise is as well be reduced, as demonstrated in this video about the introduction of HD voice in the United Kingdom by Orange, a wireless carrier, one and a half years ago.

HD Voice is made possible thanks to IP telephony, as well known as VoIP (Voice over Internet Protocol), which carries more information about each call and the rollout of better compression algorithms.

Other networks can be upgraded. For instance, Sprint is planning to deliver HD voice over its enhanced 3G network over CDMA 1X Advanced innovation. The company said the network will be ready in late 2012.

Comcast recently said it would offer HD voice to current subscribers of its VoiceEdge phone service for businesses, and Verizon is expected to introduce HD voice on its new 4G LTE network later this year, along with MetroPCS and C Spire Wireless. AT&T is working toward offering HD voice in 2013 or later.

The problem with HD voice is that both parties to a call must be using HD voice-enabled devices on HD voice-enabled networks-and those networks must be compatible-for either party to benefit from improved sound quality. Realistically, it will be years previously dramatic improvements in voice quality are widespread.

Premium on better sound quality

People who place a premium on better sound quality, nevertheless, should hear a difference in calls by the end of the year provided they upgrade to new HD voice devices and networks.
