Sprint's spectrum holdings aren't contiguous. They own a 15x15 chunk in the PCS A block and the PCS G block. Since the G block cannot be used for CDMA they have 5x5 LTE live there, 10x10 LTE live in the A block and 5x5 worth of CDMA online in the A block. 

We also have the horror that is 3x3 band 26. It is SO slow.

Why can't they use the G block for CDMA?

Sprint devices are only certified and tested for CDMA Band Class 1 which only included the PCS A-F blocks. This is because Sprint has CDMA live long before the PCS G Block even existed.

Running CDMA band Class 14 would have allowed devices to use CDMA in the PCS G Block but every device on the network was BC1 only when Sprint acquired the PCS G block; long story short, a smooth transition wouldn't have been possible. 

Sprint has been swapping spectrum with other carriers over the past few years to obtain the PCS C block (which is contiguous with the PCS G block). This allows Sprint to run wider single L1900 carriers

We have 3x3 L800 in Seattle too, but density is so good I almost always am on L2500. And when I do drop to L800, it's good enough for everything I do on my phone (including video).

I would guess your market either doesn't have handoff parameters set to aggressively move users up to L1900/L2500 or lacks site sufficient site density to survive with 3x3 L800.

I would say it's site density. Just did a speed test and got 290Kbps down. I will say there are quite a few RF issues in my area though. Ex: Even though band 25 RSRP is very good my phone wants to jump on band 26. If you want the whole story lmk. It's super weird.

So why haven't they deployed 10x10 band 25 then? I could be getting 15x10 with downlink CA. That would be the bomb!

I was under the impression they had. If not, I'm not entirely sure.

That's strange. Maybe you should reach out to a local RF engineer in that case. In Seattle I often see my phone jump from -112 L800 to -120 L1900. It makes the edge of cell experience tons better because we have 15x15 L1900.

I'm working with ZeroAssassin on the Sprint subreddit it's just he's been busy. My band 25 RSRP is usually between -80 and -90. Band 26 is about the same. I should also note that my phone isn't jumping on the closest tower either.

Yes there's definitely some sort of network-side configuration issue. Hopefully whoever you're working with will be able to resolve it. Otherwise, I would recommend emailing marci@sprint.com with as many technical details as you can, and she'll connect you with an engineer in your area.

Hit 51Mbps down in Grand Forks today on 10x5 band 25 (downlink CA). First time breaking 50Mbps in Grand Forks and on band 25. 

They finally did 10x10? Sweet. Edit; never mind they didn't that would be 15x5 if they did.

Two new PCIs detected today on the northwest side of Grand Forks. PCIs 171 and 119 are new. Not sure where these new cells are. I get -85 on RSRP indoors at the intersection of 42nd and University. Anyone aware of any new installs? I'll be on the hunt for the next few days to see if I can figure out what changed.

Just picked up another one, PCI 65. It must be further east.

Has anyone heard anything about a C block switch with Verizon in the Grand Forks area? 

There would be pretty much no incentive for Verizon to participate in a trade there as they have 20 MHz of contiguous PCS spectrum already (F+C). 

I wouldn't count on Sprint picking up the C block there.

Would or would not?

Yeah wouldn't not sure why Sprint has done 10x10 A block by now. Verizon has to benefit from swaps also. That's why you should support the TMobile merger. The combined carrier could do B2 15x15+ B2 5x5+B66 5x5+B66 5x5+ B71 10x10.

Just thought I would chime in with a report from Rapid City SD. There has been movement on the Sprint front over the past couple of months. We have approvals for 2 new sites in the city. Site 1 is a brand new tower at 611 Lindbergh Ave at the GoodWill off from Haines Ave. Site 2 is a co-location with the other 3 on the tower at 3305 S Valley Dr. Fairly certain Sprint Spectrum is broadcasting from 5 other sites in the city as well, but don't have a way to double check at this point. Lots of movement again from T-Mo so my hands are full there. If I see any more Sprint activity, I will advise.

Interesting development. Thanks for sharing!

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
