HD Voice and NV


Recommended Posts

From the link:

 

The Sprint spokeswoman says that Sprint's HD voice will be limited at launch. Not only can a Sprint customer with an HD voice handset not call another capable phone on AT&T or Verizon, but he can't even call across Sprint's OEMs, Alcatel-Lucent, Ericsson and Samsung. That means that a customer in California on an Ericsson base station can't call one in NYC on Samsung. She said it may take several months to achieve interoperability.

This is what I have been saying for roughly a year. Implementation of HD Voice (EVRC-NW) is not an airlink issue. It is an MSC and interconnection issue.

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 is a bit disappointing to read. That needs to be rectified ASAP.

Sprint can fix it's own interconnect issues though within itself. As far as HD Voice interconnectivity, I can see Sprint being on an island where the other US carriers, though their use of AMR-WB, eventually agree on HD Voice interconnectivity while Sprint is SOL because of their use of EVRC-NW.

Doesn't that depend on if Verizon does hd voice over cdma vs volte?

I could be wrong, but I doubt that we will see carriers interconnecting raw AMR-WB between one another. No, those that want to implement HD Voice interconnection will likely use some form of transcoded, higher sample rate, compressed PCM. And nothing would prevent Sprint from doing likewise.

They are going to use VoLTE. They put all their resources into LTE, and didn't really upgrade any of their 3G network, and it shows. They don't even have a 1X Advanced implementation to my knowledge so they more or less have to go with VoLTE and hope it works well for them.

Verizon has 1xRTT and EV-DO rolled out in the SD area. The call quality is pretty dang good, and I heard from a local tower guy whom I used to go drinking with after work, that Verizon is upgrading their CDMA network to try and keep up with Sprint's NV due to their 700 LTE band being overloaded.

 

Also think of it, LTE is designed to operate in an urban developed area based on how the signal was designed to compensate for reflection on the signal path, and other urban specific RF problems. It would behoove them to not neglect their CDMA 850 band when it still carries buttloads of their business customers such as Public Utilities, large coprorations like Qualcomm sales execs, and even some public public/safety cellulars in light of Nextel's iDEN going dark. As well as the roaming agreements from Straight Talk, Net10, regionals, and some of Sprint's CDMA traffic. Those are cash cows! Low negotiated throughput, crappy latency, and roaming costs.

I have been a Sprint customer for over 13 years. It is issues like this that really have me on the fence! I really am finding myself at a crossroad here, although my recent trip to Las Vegas did restore some hope in Sprint's network, but I have to tell ya, T-Mobile is Knocking at my door. Currently, almost every phone on T-Mobiles line up does HD Voice!


 


Now I know of the technical hurdles Sprint faces with pulling this off, but when is enough, enough?

And HD voice is a requirement for you?

Really? When I went to Vegas in Spring I found Sprint to be horrible. I was only on legacy sites and often found myself roaming inside buildings.

How odd. I generally haven't found that to be the case in my experiences. However, if you go deep enough into some of the mega resort casinos there is the possibility of switching to roaming. Hopefully, even that issue will disappear when LTE800 is widely deployed.

Well, let's put it this way. Sprint makes a big announcement about HD Voice and how it is greater than sliced gluten free bread. They release a litany of videos with people hearing HD voice for the first time with this fantastically wide smile on their face, and then you ask is HD voice a requirement? 

 

Of course it's not a requirement, but Sprint themselves was preaching how great it is and how you must get on Sprint's network in order to enjoy this aural orgasm. Now six months later no HD Voice, because you know, its hard to do and all. So it sure would be nice to enjoy some of the things Sprint says they offer.

 

I got on board from day one on their 4G bandwagon with WiMax and the original Evo. Of course WiMax never made it to Youngstown, but I got fringe reception at work in Cleveland and it was acceptable. So since I am not going to hold my breath on when LTE is coming to Youngstown, I'd at least like to have HD Voice when I talk to my wife with our pair of LG Optimus G's.

 

 

Ok, I have taken a deep breath and oxygen is slowly returning to my brain :D

 

When you make an investment, based on future capabilities, a prudent person has to go down that list and assess how the reality now stacks up to the promises then. This is where Sprint has 18 months left (remainder of my contract) with me before I will seriously consider alternate options.

Oh I totally agree! Inside the casinos was horrible, but I was impressed by the LTE speed outdoors. Even at my hotel, I had to be at my room window to get two bars of 3G and I was on the 25 floor of the Excalibur!

I think sprint is having trouble getting handset manufactures to build phones with this feature supported. When apple supported gsm's version of hd voice and not CDMA I began to have doubts that sprint could make this more than a gimmick. But they could just be waiting for the 800 CDMA footprint to become large enough to make it worth paying a bit more for phones (although the did launch the evo lte over a year ago or so.) . If the former is the case there is still hope with sprint/SoftBank having more clout with handset makers.

I personally think that every call I make to someone on ATT sounds like they're in the backwoods of China.

 

(Does China have a "backwoods"-y part?!)

 

The quality of the phone also makes a huge difference.  I have an EVO LTE, and my mother used to have a Samsung Replenish.  The call quality was so terrible on that.  She upgraded also to an EVO LTE, and instantly I noticed a huge improvement in the call quality.

I had a voicecall just yesterday that sounded like we were using two cups and a string. I would have appreciated hd voice.

 

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)

    • FTTH JVs are city by city as well, so it's not going to really be sector by sector. It sounds like TMo wants to be able to sell everyone home broadband, but if that requires building additional infrastructure that infra will take the form of FTTH builds rather than mobile densification. Which involves tradeoffs, but the product is better than e.g. what AT&T is doing for me right now, which is offering only Internet Air in an area where they have 100/20 DSL available but not (yet) fiber.
    • Hopefully they do not wait until these sectors get so overloaded that they start getting nasty reviews and people abandon them. Getting fiber coverage to the area of a overloaded sector can take a year or more. I also question if this can all be managed.  Lots of sectors all over the country can get congested fairly quick.  Lots of work and money to get fiber installed and there goes the profitability on the venture.
    • MoffetNathanson Conference This is a conference where the CFO talks telecom financial analysts so obviously it takes a return on investment approach.  Broadly T-Mobile divides there world into top 100 markets (60%) and small town/rural (40%). They ultimately want to have at least 1/3 market share in rural. They also look at demographics like 50+ and Hispanic.  Reputation is now starting to help them with CIOs.  Did mention c-band buildout beginning in major cities as well as continued band migration to 5g. IMO they may become more aggressive at offering 5g phones to LTE holdover and 5g users without VoNR at a future date. mmWave not discussed. Price increases not discussed iirc. Did mention spectrum purchases from speculators. $9 billion all goes through same ROI process. FWA is down to hexagonal patterns by sector of fallow spectrum. Fiber JVs will go where sectors are overloaded.
    • I am lucky to be served by an excellent fiber ISP and that is the only reason I haven't tried TMOs FWA. Once you go fiber, it is REALLY hard to go back. The choice of sub-10ms ping times is a very artificial bucket, FWA will seldom get much below 10ms ping times but fiber regularly gets me 1-3ms ping times. Basically, at around those times, the speed of light and the distance you are from the server become the limiting factors. As an aside, my internet provider, ZiplyFiber, has been awesome. They peer like crazy at all the major IX in the area and, as a result, you end up with what essentially amounts to direct fiber connections to the vast majority of major data sources. While it isn't sexy, it makes my 1Gb/1Gb connection load pages significantly faster than my works 10Gb/10Gb connection. On the "sexy" side, they are also fastest ISP in the nation. They offer up to 50Gb/50Gb via a direct fiber connection to the router, albeit for an eye watering $900/mo.
