Major US carriers to offer HD Voice by year end; make calls sound drastically better

by Sayan Chakravarty

With HD screens, HD photo and video recording almost everything is going HD in cellphones, how about HD Voice on calls? That’ll be cool! Every once in a while the dropped calls, break-in conversations and shoddy voice quality don’t fail to get us gravelled. But it might all become a thing of the past once HD Voice services are introduced, and don’t worry, you won’t have to wait too long for it. All the major carriers across the US plan to deploy the service by the end of this year. T-Mobile has been supporting the technology since January and has finally launched the service for iPhone 5. AT&T and Sprint are to join in soon, but Verizon is in no hurry and will join the party only by the year end or next year.

Without going too much into the technicalities, in plain words the service providers will have to move their calls from 3G network to 4G LTE network and use wideband audio technology. Similar technology is used in VoIP Apps like Skype and it’s not entirely new as many European carriers already support HD Voice over CDMA or GSM networks. The sound transmitted will be much clearer and the quality will drastically improve. But there’s a catch, HD Voice is not supported by all cellphones and the service isn’t interoperable. Most of the latest smartphones support HD Voice, and once the service is fully operational chatting on phone will become a little more pleasant.
