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.

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!
I was just wondering if anyone had any idea on when the LTE upgrades would happen in St. Louis? I have been a loyal sprint customer for a long time and just realized that my 3G speeds are around 120kbps and that is horrible! Also 4G is around 1-2mb! I work right in the middle of STL and these are the speeds I get? I am excited about the new LTE and cant wait but I am hoping for a nice 3g speed increase too.....

Initially T-Mobile was simply slapping n41 panels onto existing sites which meant that NR+LTE aggregation aggregated all available LTE bands with NR. Now, T-Mobile seems to be replacing 600/700MHz antennas every time they add n41 and as a result, the city is getting covered in split eNB IDs. On a local (legacy) 600MHz site by my home, when I connect to n71 it's n71 + Band 2 + Band 66 + Band 71 or Band 12 for a combined total of 50MHz of spectrum. However on my home site, because of the split eNB, when I force my phone to connect to n71 it only aggregates n71 + Band 2 + Band 66 for a total of 45MHz of spectrum. It seems weird that T-Mobile is allowing this to happen instead of fixing it so that they can squeeze as much performance out of their network as possible. 5MHz of LTE is not much but it's still an extra ~37Mbps of speed and capacity that could be provided in NSA mode. Interestingly this problem is not something I experience in LTE-only mode much anymore. My phone seems to have no issue aggregating LTE bands across the split most of the time. Another thing that has been bothering me is that according to the FCC dashboard T-Mobile has 400MHz of spectrum in the 39GHz band here in NYC that they won in December of 2019 but they haven't done any upgrades to actually use that spectrum here. Instead they've been relying on the two 50MHz blocks aggregated together in the 28GHz band which performs worse than n41 on average.
Confirmed that AT&T is running dedicated n5 here, at 10 MHz, by process of elimination. LTE is 10x10, and H+ is 5x5. They might be running DSS or n2 or n66 but I kinda doubt it. Guessing they aren't running H+ on every site anymore either; signal appeared a good bit weaker than the B5 LTE signal when I band selected to it. Also, B14 is pretty obviously not on every site here; signal levels at my place are comparable to B2 and, well, 700 should be a lot better than that. Explains why I wasn't seeing B14 aggregated normally. Though apparently they have 25 MHz of B66...one 15 MHz carrier, one 10 MHz.
