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.

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.
Closer Look at the connectors on the bottom of the antennas
Special Case Mexican IBEZ Setup
Note the lack of 800 MHz RRUs though the antennas are capable of 800 MHz.

Just a bit of insight. I live near UMD in Duluth, MN. Sprint's signal is clearly much 'dirtier' with a 1.0 SNR compared to T-Mobile's 20.4 SNR. I don't have a screenshot from the same time, but I get about a 22 to 29 SNR with T. I know that AT&T uses RRU's but I'm not too sure about Sprint or T-Mobile. Also, I didn't even know they had L2500 where I live, but I force checked it on my Samsung S7 (AT&T).
Did you know that with many Sprint (Uniband) LTE Android devices, the signal strength indicator at the top does not show your LTE signal strength? Even if 4G or LTE is displayed next to it?
That's right! This signal displayed here is your 1x (voice signal), and it is not your 3G EVDO signal strength, nor your LTE signal strength. Regardless of whether it says 3G or 4G next to it. This is the cause of a lot of confusion. Also, third party apps like NetMonitor do not show accurate LTE signal strengths. They also only show the 1x signal strength, even though they may reference being connected to LTE.
The purpose of this thread is to help educate the masses, because many people think they have a strong LTE signal, when in fact they do not. And then they are unhappy, thinking that Sprint LTE is really slow, even with a strong signal. LTE performance is very signal strength dependent. So, when you have a weak signal, you can expect much slower than peak results.
There is only one accurate way to get your LTE signal strength, and that is from your LTE Engineering screen in your Debug menu. And we will discuss the different ways to get that below.
...In HTC, Motorola & LG Sprint LTE devices:
Go in to your phone app, and dial ##DEBUG# Select LTE Engineering Go down to RSRP. The number under RSRP shown in dBm is your LTE signal strength. ...In Samsung Sprint LTE devices:
Go in to your phone app, and dial ##DEBUG# Enter 777468 for your lock code Select LTE Engineering Go down to RSRP. The number next to RSRP shown in dBm is your LTE signal strength. ...In the Galaxy Nexus, Nexus 5:
Go in to your phone app, and dial *#*#DEBUG#*#* Enter 777468 for your lock code Select LTE Engineering Go down to RSRP. The number next to RSRP shown in dBm is your LTE signal strength. The LTE Signal Strength Scale:
Now you have determined your actual LTE signal strength in dBms your device is receiving, you can use the following scale below to determine its strength:
Better than -88dBm RSRP is a strong signal Between -89dBm and -96dBm is a very good signal Between -97dBm and -105dBm is good Between -106dBm and -112dBm is fair Worse than -113dBm RSRP is poor Feel free to link people to this thread for explanation. Hopefully, this will clear up some confusion out there!
From ze reddits..
eNB 43383 in Gowanus is another one of those sites with more backhaul than normal. It's the first one I found that doesn't have LAA or mmWave. It's also a weird site to have so much backhaul since it's not in a particularly busy area with the exception that it covers a Whole Foods. I got this while in my car without LOS so I'm sure I could get faster if I got closer. This is the same site where I was getting nearly 500Mbps on LTE while indoors a couple of months ago.
So far can't tell any issues on Android 12 beta and S21 but if the author wants any specific testing let me know!
