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.
