B26 appears to be optimized in SF as well. Very few sites don't have B26 (basically every B25 site does). I think we'd be able to get away with VoLTE.

 

That said, I don't see the harm in enabling it, but letting it default to off. Don't advertise the feature yet. Let users discover it and turn it on in the settings. Sprint can use the data to fill in the coverage gaps and work out the bugs before an official, advertised rollout.

That would be nice

I'm pretty confident at this point based on conversations with my sources that CDMA Fallback is not ever going to be ready for prime time. Sprint can really only go VoLTE when B26 is on every site nationwide and optimized for coverage.

So chances are realistically that this isn't going to happen until post NGN?

B26 sucks where I am.

 

At least you have B26 lol they don't have B26 at all in seattle

You do know that ATT VoLTE has the wonderful plus of SRVCC being implemented alongside well developed fallback to their WCDMA / GSM network right?

 

With utmost confidence, I will guarantee there is not one major top 100 metro that Sprint services which can deploy VoLTE without CDMA fallback today. Not one. Sprint is far too consistent with its inconsistencies.

Markets like Denver where the network is very strong seem plausible, at least to me. Do we have any idea when CDMA fallback will be deployment ready? Lagging behind the other three carriers even on tiny things like this drive customers away and I can't imagine that's what sprint wants.

How would that setting be automatically activated or adjusted per market? It still would require user intervention.

 

And no Sprint market, not even Kansas City, is ready for VoLTE. It would wreck reliability, which Sprint generally leads in RootMetrics now.

AT&T seems to have implemented this fine...VoLTE works ONLY in AT&T's VoLTE markets and CSFB is used in other markets. Just to clarify my idea is not rolling out VoLTE over the whole footprint, just allowing it in strong areas.

How would you plan to explain that to typical, uninformed consumers?

 

"Turn this setting on for simultaneous voice and data.  Turn it off if you want to avoid dropped calls."

 

That just would make Sprint look bad.

My idea was to only have it enabled in markets where the network performance was overall pretty good like Denver.  Essentially what AT&T is doing.

Well I have streamed Pandora on a 56kb/s 1x connection, so 128kb/s would be plenty and I probably should've clarified a little bit better. I was wondering if it has been stated if it's going to be throttled LTE or if you will be locked to Evdo/Ehrpd or 1x?

Throttled LTE from what I've heard.

No, a 5 MHz FDD block cannot accommodate four CDMA2000 carriers. That would leave no guard bands and actually would extend outside the block.

Am I forgetting any?

iPhone 6S?

They could also make it a ption in call settings like Verizon and T-Mobile does. If you don't want to use it just turn off volte.

Definitely

Sprint already leases its Alaska PCS A-F license (D Block).

• Anchorage: http://wireless2.fcc.gov/UlsApp/UlsSearch/leasesList.jsp?leasetype=null&licKey=10634
• Fairbanks: http://wireless2.fcc.gov/UlsApp/UlsSearch/leaseMain.jsp?parentKey=10687&licKey=3073179

I don't see anything on the SMR though: http://wireless2.fcc.gov/UlsApp/UlsSearch/license.jsp?licKey=8377

 

And GCI/AWN already have substantial holdings of their own too.

D-Block is 5mhz so room for 4 1.25mhz CDMA carriers, G block for 5x5 LTE, whatever BRS/EBS spectrum they have but no 800 at all? Also will sprint customers only be able to use wireless networks in these blocks or will they be able to access the networks run in the other PCS A-F blocks by GCI?

So PCS G and BRS/EBS, which is good, but no PCS A-F or SMR...?

 

I know all of this is still new, but is that "normal"?

Remember GCI does have its own PCS holdings. I think that sprint customers will be able to access wireless services on those bands along with the bands sprint is leading them.

I think he is referring to just that though. In markets where Sprint's 800MHz indoor penetration is good enough, they could launch VoLTE. That's what AT&T did and it has been working out for them decently enough.

Exactly.

UPDATE!!!

This is great! Hoping it will be native.

Yes. And AT&T will deploy WCDMA only at new sites and Tmo will deploy some sites with 700MHz LTE only. So it's not unprecedented at new sites.

I AT&T's moves are more justifiable because I'm pretty sure it's safe to say everyone on AT&T has a umts capable device. Idk about T-Mo, I think what they are doing is questionable...

Can't sprint light up VoLTE in strong markets with 800mhz like Denver? I don't think if they did it on a market by market basis (only lighting up VoLTE when the coverage and speeds are good enough), we wouldn't drop that many calls...

You wouldn't leave anyone to hang and dry. The only people who would be effected are those who have a 3G/Wimax only device, and roam on 3G. They will now get put onto native 1x. Otherwise, the only difference if you have a 3G/Wimax only device is you'd be going from roaming 1x to native 1x. This will actually help even cause you'll use less of your roaming bucket allotment.

 

Plus if you are on a 3G or WiMax device, you really need an upgrade anyways. There are always stragglers when it comes to phones, and those stragglers shouldn't hold back advancements for the rest of the masses. They can get a brand new LTE phone that is way better for bucks these days.

 

Im not saying current coverage needs to nix EVDO, just new coverage. Though that day will come when EVDO gets nixed nationwide, and you bet that there will still be people without LTE smartphones.

There are too many customer with non-LTE phones for them to expand without EVDO. There are too many stragglers ????. Plus as Robert said its not like EVDO is creating a problem for LTE...

Lets not forget that public WiFi is not always secure. A few years ago there was a app on rooted devices that allowed me to kick anyone off of WiFi on a open network or one that I had the password to and hog the bandwidth to myself while hidding my phones presence. Brought down a denny's just to test it. I use it but I don't trust public WiFi. The other carriers don't have to make this choice only Sprint. Most don't care but it doesn't take much to hack a open network.

WEP and WPA TKIP can be hacked easy in most cases too.

@ robert, if they set them up like an mnvo, I don't see why they couldn't partition or otherwise separate and manage the traffic, much like sprints own mnvo's and various roaming agreements have differing network management.

I'm sure they can but we don't want their high usage to have a negative impact on sprints main customers' experiences.

With regard to this, does this mean that Sprint may get Swifter to start doing some work sooner rather than later?

 

Do you mean Swiftel?

I have a guy at work that would leave AT&T for Sprint if only he were able to do voice and data at the same time.

 

He does a lot of tethering (legal) with his iPhone and Macbook and would hate to lose a data connection when receiving or placing phone calls.

 

I've never really used voice and data at the same time so I can live without what I've never had, but potential new Sprint customers may not want to give up that capability.

When I first left AT&T for sprint I was appalled that you couldn't use data while on calls and it still bugs me so I can't wait until the VoLTE launch.

The equipment Sprint uses for 1x and EVDO is combined, so there is no cost savings to skip EVDO. However, EVDO can not be turned on and thus not use any spectrum.

The problem is that this would hang customers with non-LTE devices out to dry and sprint probably won't do that.

I have only hit 100

Wow so slow ????????????

Where I get 2x Ca b41 I average 75-100!! It's like omg!!!

Then I hit a tower that doesn't .. Then it's like whoa!!

Yea you get used to speeds north of 100mbps fast xD

 

Just stumbled across this...is this the start of VoLTE?
