Ericsson AIR6488 B41 Massive MIMO Antenna Radio Unit
This 64T64R Massive MIMO units will be likely found in Ericsson vendor territory from network vision days. It will be easily identified by it's lack of an external remote radio like Sprints typical LTE equipment and its size being significantly smaller than Sprints existing 800,1.9, and 2.5 equipment.
Here are the Alcatel-Lucent (ALU) Network Vision equipment for Sprint. Their equipment consists of 2x base stations, 6 or 9 Remote Radio Unit (RRU) setups, and 1 standard NV antenna of with connectors on the bottom (4x PCS, 2x SMR).
Below are images of Alcatel-Lucent equipment. In these images, you will find Alcatel-Lucent base stations, Sprint Network Vision antennas, PCS 1900 & SMR 800 RRUs, and their configurations.

Alcatel-Lucent 4x45w 1900 MHz B25 RRU
ALU 2x50w B26 800 MHz RRU [KMW Communications]
Older Panasonic Setup [4x40w 25 MHz B25]
Standard Alcatel-Lucent Setup
Utilizes 2x50w 800 MHz B26 RRU and 4x45w 1900 MHz B25 RRU and compatible antennas.

Special Case Mexican IBEZ Setup
Note the lack of 800 MHz RRUs though the antennas are capable of 800 MHz.

I started working on the Raspberry Pi 3b Plus tonight with an Sierra Wireless em7565. This one has all those cool features that I was describing up top.
Not bad for ~39 bucks. I was waiting for a few open source firmwares to get through the compilebot6k's toobs; this one is built now. Some use modem manager or openWRT for the router side. This LTE radio is band(s) 2/26/41 capable on the Sprint side. Band 25 did not make the cut, but was on previous Sierra builds. This is a tester radio so there is a slight chance it will appear down the road. It has just about every other LTE band.
This is an example of the debug screen. GMO is nearest so we only get 26 from a far site. No 41 in our zip yet.
The best part is I can plug an MC7455(that would be Modem#2) or another EM7565 in and it can hop over to that or I can direct load balancing. I just wanted to show the EM7565 authenticated below.
Another shot of my terrible reception.
Here it is out of the armor.
So, we have a stable software image. I will get it built and add some GPS features, then test on band 41 in Myrtle where present. We have one site w 8t8r gear to test 3xCA on, so it might be a minute. I am in 2xCA MM areas through the week. I will see how it likes the Magic box too.
I should have a true GB ethernet router to massacre in the next couple of weeks with software images already set to go. I can embed the radio beyond a USB adapter. It still requires m.2>mPCIe but that is one less failure point and better throughput. This was a great breakthrough in affordable and small solutions for us. I have to go to bed and then work now.
Thank you so much for bringing light to this! I would have never known about it had you not posted it! You've saved me a lot of money and lowered my bill moving forward! It wasn't an easy process, but well worth it.
Unlocking the phones was surprisingly easy. But the small hiccup came with my final bill. When I received it, I thought I was screwed when I saw that the ETF was included. I almost paid for it too, but the frugal in me decided to call Sprint (couldn't hurt, right?). After an hour on the phone with a US supervisor, my account was credited for the full amount of the ETFs. I walked away Scot-free!!
Thanks a bunch OP! I'm trying Verizon's throttled unlimited data plan. Excellent reliability in the city, but there are certain key spots where I need my phone that aren't great. I don't know if it's the throttling or the network.
