Yay! Galaxy S3 is HD Voice ready!

---

Meaning software enabled. I'm sure Sprint can do the same.

" The little blue marble we call Earth is no stranger to HD Voice -- it's been around commercially since Orange debuted the service over its 3G network in Moldova nearly three years ago -- but the technology still hasn't been officially deployed over an LTE network. That is, until SK Telecom launches the service later today. Doing so will allow the South Korean carrier to snag the crown for world's first before Sprint, which recently announced that its network won't have it until later this year. It's a win-win scenario for the company: HD Voice over LTE is meant to vastly improve call quality and reduce latency for the customers, while lessening network strain and offering new revenue-making opportunities for SK Telecom. What about devices? It hasn't announced any brand new smartphones that can take advantage of the service, but the company's ready to pre-load the Samsung Galaxy S III with software that enables HD Voice capability, and is planning to push an update to current owners of the flagship device. If you're the type of person that still makes the occasional call, this kind of progress should come as pleasant news."

This will be great, but I don't think Sprint will consider it until their LTE rollout is more available to their customers.

I read that there are two types of HD Voice. There is HD Voice over 1xAdvanced and HD Voice over LTE. I was hoping that Sprint would enable HD Voice over CDMA 1xAdvanced. 1xAdvanced also allows better channel efficiency. I would think it would be a win-win.

That's exactly what the are doing. Volte wont be rolled out for quite a while.

VoLTE will also not have as good coverage as CDMA 1X, even on the same frequencies, and especially in the case of 1X Advanced. LTE performance begins to rapidly deteriorate once the signal weakens to the point of -90 dBm, and becomes practically unusable at -100 dBm. CDMA 1X Advanced doesn't start deteriorating until about -100 dBm or lower, and can be maintained until -110 dBm. That translates into a very large penetration and coverage advantage for CDMA.

Sounds Great. But i am still waiting for LTE in my area

This is amazing news. I make a lot of calls and my biggest gripe with any carrier is that the call quality is pretty bad. Hopefully with HD voice, phone sex will be a lot better.

Are you guys sure the SIII has HD Voice on Sprint? I thought only the Evo LTE has it because its a Network Vision contingent feature not an LTE feature.

I'm not sure what is needed for HD Voice to work. Does it need a special piece of hardware or does it just need the correct software? I would think that the hardware needed is already there and just being used for something else (since HD voice is just commandeering the frequency it needs) and an update could actually cause it to be supported. Since HD voice is very rare I'm not too sure what all it entails.

Sprints HD Voice is apparently different than regular voice over LTE (VOLTE) and there's no word if they will adopt that. If you Google it you'll see that they pledged to turn on HD Voice for Evo LTEs a couple days ago but they didn't mention the GSIII.

EDIT: So yeah, HD Voice is apparently a Sprint alternative much like WiMax is and only the Evo LTE supports it I guess.
