Someone here can probably explain this, but what exactly is preventing Sprint from doing full on VoLTE? Lack of macro density? Lack of coverage? Something in the core of their network? I remember years ago their excuse was lack of fallback to CDMA, but what's causing it today? Why can't they do a full scale VoLTE launch like Verizon did? Or at least a market-by-market launch like AT&T, where they know they have the LTE reliability and capacity?

Thank you. I agree completely. You mean to tell me that Sprint, who has a nationwide roaming agreement with Verizon for voice/text, does better than T-Mobile? Shocking.

First, those are 3rd party sources. If that makes me "hate them" then yes I'm a hater LOL. Secondly, I don't hate T-Mobile or Sprint. In fact, I have a line with T-Mobile. AT&T just has 4x as many cells where I live... T-Mobile only has a few less than them... Sprint has like 9 sites cover 280K people.

LOL, ok... www.rootmetrics.com/en-US/content/mobile-performance-in-the-us-part-1-performance-across-the-entire-united Sprint ranks ahead of them in call and text... which they can roam on Verizon for. https://opensignal.com/reports/2017/08/usa/state-of-the-mobile-network www.speedtest.net/reports/united-states/ https://www.pcmag.com/Fastest-Mobile-Networks Don't be delusional. *based on Sprint's interpretation of Nielsen data

LOL

All of the core specs are identical except for the size-dependent ones (battery, display size, resolution) I think a lot of the hype for the 2 XL vs the 2 is how much better the design of the Pixel 2 XL is as opposed to the regular Pixel 2... obviously talking about bezels and the curved display. You can't go wrong with the smaller Pixel, it has all the same features as the 2 XL and a better (Samsung) display.

Thanks for clearing up the confusion. I wonder why Google's spec page doesn't show the same thing. It seemed a little ridiculous to me that they could make 4x4 work on 2 but not 25...

So the Pixel 2/ Pixel 2 XL support 4x4 on B2 but not on B25? That seems like an odd omission... is that a typo?

This is an interesting experience given that Verizon's VoLTE is prioritized on QoS and the handsets will hold LTE for the phone call than it would for a normal data session... curious as to why this happens to you, and how Sprint has better signal than Verizon there.

Same thoughts here. Looks very similar to AT&T's LTE reach (in my experience)

If you open the app, leave the app for maybe 5-10 seconds and then reopen it (without force closing) the Cast option should show up. I've been running this build for about a week.

Old, but here's some 3xCA from my iPhone 7 on Boost's unlimited plan in Duluth, MN.

No QoS like the other 3? That won't be good. Their network is already saturated enough as is in some areas.

T-Mobile runs 40 MHz of AWS, 30 MHz of PCS, and 10 MHz of 700. That's 80 MHz, which isn't that much less than Verizon given that T-Mobile has less subscribers. That's probably also why they hold the speed and network crown in NYC. AT&T runs 30 MHz of PCS, 30 MHz of 700 (12+29), and 20 MHz of WCS... so the same amount that T-Mobile has on air. AT&T also has B14, B66, and B5 to tap into. So another 65 MHz of spectrum untapped for LTE. It'll be interesting to see what they do with it. I would think that AT&T is trying to swap licenses to make their 30 MHz contiguous (15x15 B2 LTE) as opposed to a 10x10 and 5x5 slice of B2. But I guess we will see.

That's how I imagined that this 12:1 configuration would work. PCC would be the normal 72/18 config, Maybe even one more oriented towards upload... and then SCC1 and SCC2 (SCC3 even?) could be the 108/9 configuration. I don't see why this couldn't work. Maybe WiWavelength could clear this question up.

It's done on a person-by-person basis.

That's interesting. T-Mobile runs AMR-WB 12.65 Kbps (HD Voice) on UMTS/LTE, and AMR 12.2 Kbps on EDGE. When on a VoLTE call with Verizon and AT&T subscribers, or any call on 3G or higher with other T-Mobile uses an HD Voice codec. Every other carier in the US uses the same codec. Sprint on the other hand, uses a weird codec for voice calls, known as "EVRC-NW" and is only compatible with other Sprint users that are also using an "HD Voice" capable handset. When calling any other carrier, audio quality is horrible.

I'm sure that they have an "algorithm" of sorts, but all the factors you mentioned are probably put into consideration when being placed on a band. In heavy traffic on AT&T, I will see myself on B2 a lot more even though my device supports 3xCA from 30+4+12. I would think the network would ideally work in the order of 3x41>2x41>41>25 second channel (if applicable)>25 first channel> 26> EVDO 1900> EVDO 800 (if applicable)> 1X 1900> 1X800, but nothing works perfectly.

Pure curiosity, but does it actually work? Do any end devices support it currently? I know the S7 and S8 have the antenna, but is it active on either device?

10x10 FDD uploads peak at 25.5 Mbps at 16QAM, so you're not seeing any higher than that. Sprint does not have any 64QAM upload enabled on their network... feel free to correct me if I'm wrong.

It might be inconvenient, but I would recommend going to airplane mode for 15-20 seconds and then turning it back off. That should reconnect you to the network. Does EVDO perform better at that location? Can you just disable LTE? Not sure if there's a way to lock 26 out on a 6P. Maybe if you're rooted.

WCS Spectrum goes from 2305-2320, and 2345-2360. Feel free to look it up yourself... or just read the image below. or this one: or even this one, from the FCC itself: Currently, B30 only covers 10 MHz of spectrum for LTE access. I won't argue with you about that. But I am not operating off of my own assumptions. If cleared by the FCC, AT&T could maybe ask for a sort of WCS-2, or Band 71.

B30 is live on many sites across the country and currently seems to be their main initiative. I see it all over where I live and even in rural areas. It is their only "greenfield" spectrum for LTE deployment besides 29 that is nationwide. It is only 10x10 MHz, because of issues with Sirius XM Terrestrial filtering and licensing. All deployments I have seen seem to be 4x2 MIMO. 15x15 MHz is possible with their spectrum once they get something figured out with Sirius. Something interesting to note is that they start at a lower power level and increase it as they can without interfering with Sirius. If you see a new B30 deployment, it will start at a really low, almost unusable power level unless you're in an urban environment. Yep.
