Anyone see this....?   http://www.lightreading.com/sprint/sprint-delays-hd-voice-launch-to-q2/240153470

Good luck with that. Even if all carriers in the future adhere solely to the LTE standard, disparate spectrum bands, technical limitations in devices, and allegiances/feuds among the carriers will pr

That it won't work with a AT&T or VZW subscriber, for instance, isn't surprising to me. That it won't (initially) work between Sprint subscribers if they're located in different vendor territories

Really? I wonder if it was a local issue. I've used every phone under the sun, and have yet to come across that issue, unless I was in a low signal area (-110dB 1x)

 

I was home, and supposedly, the tower a block away is now NV-ready, and has been for three weeks. Sadly, the 3G speeds are still under 300kb, and the voice call I made seriously sounds like an AM country radio station as youre climbing a mountain - static, distortion and muffled sound.

 

Signal was -81.

I wonder if it's your device?

I dont think so, it is usually fine, and I did a wimax test and that came in at the normal 5-6mb.

 

Yeah but that's different. All the voice calls are connected over 1x, which is totally different from WiMAX.

 

The only reason I say that is because normally, CDMA 1x has the best sound quality, and in my personal experience, the only time there was an issue was when I was in a poor coverage area, or the hardware was defective.

Right, but as I noted data speeds were poor too, on 3G, but fine on 4G. So at least half my phone is working!

 

I think its something with the tower. And yes, Ive had much better voice on sprint than I ever did when I was on AT&t. That being said, I still want HD

The voice quality on the Nokia Lumia 521 on T-Mobile UMTS is nothing short of amazing. I was blown away the first time I tried it, my first impressions were how much bass and clarity there was! Instead of being real flat it was more natural like having the person in the room. I thought it seemed a little better then a good VOIP call.

my iPhone on Sprint is good and natural sounding too, I actually enjoy most conversations on it (depending on what carrier the other end is on) but I really liked HD voice!

I wouldn't mind my next Sprint phone to have it, I always think audio quality on a phone call can be better. 

 

My previous S3 didn't have as good of sound quality as the iP5 IMO, I never liked talking on it much and felt that listening was more of a strain especially in louder environments (I think Apples noise cancelling works better) 

 

As for talking to people on AT&T my head hurts after those conversations. (or worse yet Verizon)

Call quality going from CDMA to GSM is always going to suck until we have upgraded from that to LTE to UMTS or LTE to LTE HD Voice with PCM carrier interconnect.

Sprint to T-Mobile doesn't suck. It's just ATT

Sprint currently uses the ulaw codec to interconnect with other carriers and to backhaul all the calls from a tower to a switch. This is the standard legacy codec for the PSTN. 

 

AT&T and Verizon are hit or miss on if the call is backhauled via ulaw, usually it is compressed. With AT&T, the call is further degraded because of the half rate GSM over the air codec between the phone and tower. 

 

Verizon has the option of ulaw or g729 (a compressed codec) from the tower to the switch and switch to the PSTN. So call quality can vary with them. I do not know what codec they use between handset and tower though.

is nationalization of the wireless infrastructure.

Had a horrible quality call between two Sprint GS4's today... Have they started deploying this yet?

Not to my knowledge, I wonder if they want NV 1.0 done before start deploying HD voice.

I had probably the worst sounding call I ever had two days ago; it was a Sprint/Verizon call. When I heard the word "under water" described I apparently took that with a grain of salt, but the person I was speaking to really did sound like she was under water! not only that but also sounded like she just had her mouth numbed from the dentist, and had a mouth full of shit as well, combine that together and I couldn't understand a word for the life of me. I had to call back on her landline and it was clear as a bell, obviously it wasn't me! I held that clear call just fine inside with just 1-2 bars on my iPhone. 

 

I never realized Verizon could sound that bad...

Oh yeah man! It's not all gold and diamonds like they make it out to be. My parents live out in rural Berkeley county SC. Zero chance of LTE out there. I can't even understand my mom when she calls. I end up calling on her landline. The funny thing is that I have decent 3G and voice out there with my Sprint iphone.

It could be that they want HD Voice to work between the three network vendors and they haven't been able to figure that out yet.

In the meantime anyone with iOS 7 can use FaceTime calling! the closest thing to VoLTE I've used to date (technically you could say it is, since I used it over LTE haha) 

Voice quality is phenomenal, and it works great on LTE (no idea about EVDO yet, EVDO usually sucks around here though, so I'd imagine the call would suck too) Also it's interoperable between the other three carriers! hahaha

I do the same thing with google hangouts, beats Sprint's voice quality by a mile lol

You can also use Google Voice calls over data through apps like GrooveIP. Works surprisingly well.

Yeah I've tried that before, when I had an S3 and when my brother got a Nexus 4 on TMO. It seems like it requires a much more stable network connection then the FaceTime calling does.

      Network Vision/LTE - West Washington Market (Seattle/Puget Sound Region)

      Drove by there and it definitely isn't on the Northlake property. It was very late, so I couldn't see much else though. Did some more sleuthing on GoogleMaps and I suspect it might be this powerline site nearby: Google Maps I will go by there in the next couple of days during the daytime and see if that's the case.

      Vinegar Hill is getting the Brooklyn Heights treatment now with regard to small cells. I mapped two more small cells in the neighborhood in the past few days so now T-Mobile is up to 8 of them in such a tiny neighborhood. While it's cool they're doing this since it means outdoors you get a consistent 400Mbps+ almost everywhere, it sucks because they're obviously deploying so many of them to make up for their lack of a macro site in the entire neighborhood. Because there isn't a macro, the small cells have a greater coverage area than you see in other neighborhoods and you often connect to them while indoors but coverage and speeds fall off indoors much faster on small cells than on macros in my experience.  Even Dish has better coverage than T-Mobile in Vinegar Hill since they added the site on top of the Extra Space Storage building alongside AT&T and Verizon. T-Mobile needs to get in line with their competitors there.
