re: Sprint Delays HD Voice Launch to Q2
Late reply. But I can thank my trolls for that. :) 

"You're commenting on an article that's a full year old. Sprint just now said it will launch HD voice nationwide this summer, so i think it was safe to say it'd be quite awhile back then...." 

So does that mean my point is invalid? Absoloutely not. If anything, I was speaking as if it was still April 2013 since my statement was correct in relation to the original article. 

HD Voice was commercially released in the United States to potentially 45 million subscribers in January of 2013 on T-Mobile. Your article was written in April 2013 which is four months later. That is plenty of time for some people to hear HD Voice for quite some time. 

I mentioned that what you said (that I quoted) was ignorant because it was just that, ignorant. Here's a definition of the word ignorant: "lacking knowledge, information, or awareness about something in particular." 

I did not call you ignorant so please do not take that as a personal attack. 

It is always important [and responsible] to report the news as acurately as possible in order to maintain your website's credibility. Otherwise, why would I or anyone else bother to come here if the information is inaccurate.

Dear Fabian -- You can disagree with someone without insulting that person. You should try that once in a while.

That's an ignorant thing to say. 

You're writing articles in the "3G/HSPA" section of this website yet you don't have a clue about what you're talking about.

I'd argue that the 45+ million subscribers (assuming that all subscribers have capable handsets) that T-Mobile has are hearing HD Voice. Not to mention that HD Voice has been commercially released since 2008.

re: Sprint Delays HD Voice Launch to Q2
 

It's not compatible with anyone's network. HD Voice is network-specific for the moment. 

So while T-Mobile USA and Orange in Europe may use the same HD Voice standard (AMR-WB) over their 3G networks (UMTS/HSPA+), the phone call will default to the non HD Voice standard of AMR-NB. 

Network Vision may be a prerequisite for HD Voice but it's not very wise to assume that it has to do with the LTE network. It has nothing to do with the LTE network. This is not VoLTE.

VoLTE deals with packets (packet-switched) and is no longer circuit-switched. With VoLTE, minutes will be a thing of the past as voice calls will probably be counted as data, because it's just that, data. There may be some form of conversion à la m number of songs can be stored in n size of storage or m number of songs can be downloaded using n speed of internet. But in all reality that is one of the main reasons why the twin bells have not launched VoLTE yet (data buckets/shared data anyone?). Additionally, VoLTE requires HD Voice codec AMR-WB (more data usage). How do you guarantee unlimited voice calls when you're (twin bells) already claiming that unlimited data is gone for good? Only MetroPCS has implemented VoLTE in the US. Another reason is coverage. It is easier to initiate a voice call using circuit switching versus packet switching when you've got a low signal. A low signal usually entails a low data connection which would be terrible when attempting to send packets. Packet loss ensures bad quality of service (ever Skype'd on a bad connection?).

Sprint has implemented HD Voice codec EVRC-NW (Narrowband-Wideband) over their CDMA network. Network Vision upgraded their 1x network to 1x-Advanced and 1x-Advanced brought HD Voice along with it. 

The unfortunate thing for Sprint and Verizon is that only select phones will be able to access HD Voice over their CDMA network, unlike the HD Voice that T-Mobile (eventually AT&T) and the rest of the world uses. 

This is why people were able to use HD Voice on the iPhone 5 in January of 2013 (when T-Mobile launched HD Voice) even though T-Mobile wasn't an official carrier. The other 3 official carriers did not support this feature and still do not to this day! 

Apple has started to more and more build their phones to international standards that T-Mobile already complies to: HD Voice, DC-HSDPA (42Mbps) and HSPA+ (21Mbps), which both include simulatenous voice and data.

re: Sprint Delays HD Voice Launch to Q2
How do we know that they are not using 3GPP's AMR-WB? The codec and the transport are not tied together. It would actually make a lot more sense that it would be using 3GPP's AMR-WB codec as any phone that will support VoLTE will already have support for that codec. The network also needs to support it; since Sprint is moving towards LTE and especially VoLTE, it would make much more sense that the Sprint HD voice service actually did use 3GPP's AMR-WB codec.

re: Sprint Delays HD Voice Launch to Q2
No, it's not compatible with AT&T nor T-Mobile...another big limitation. Sprint said that "Network Vision is a pre-req for HD Voice," so I think it's only supported on the LTE network. The phones listed are all LTE-compatible.

re: Sprint Delays HD Voice Launch to Q2
Is this HD Voice service offered over their 3G CDMA network? If so, it's most likely not compatible with other HD Voice services offered by AT&T and T-Mobile, which are based on 3GPP's AMR-WB.
