How to Spot Sprint 8T8R TD-LTE RRHs (Alcatel-Lucent)

Recommended Posts

How can someone tell if the tower or cell site was retrofitted for 8T8R? Or carrier aggregation was completed without looking at it? Is there a way to check on the phone that its picking it up?

The first three digits of the gci will increase by one. The last two characters of the gci, which indicate sectors, will move to the next series. For Samsung markets, was was 00, 01, or 02 becomes 03, 04, or 05 to indicate second carrier. SCP will indicate it with an exponent of 2. CA we have not seen yet.

Recommend you download Signalcheck Pro for $1.99 from google play store. Other option is dial ##debug# and choose LTE.

CA may be out there and you should have the right phone to find it. Good luck!

Ok Awesome im going to try that. If i hit *#0011# would i be able to see anything on that screen to indicate 8t8r?

I connect to this tower when i am home and CA is not enabled yet ,is it 8t8r ? i am on band 41 even in basement.

That's one of the few sites where Clearwire and Sprint is colocated on the same rack.

 

The Clear equipment have the Samsung dual mode RRUs which broadcast both Band 41 and WiMax. Some Samsung clear equipment are capable of 2nd Band 41 carrier and carrier aggregation but most won't have 2nd B41 carrier and / or CA enabled until WiMax is shut down.

Looks like Sprint using tri-band antennas in San Diego.  Does this support B41 8T8R?

Great find! Since each sector has 3 panels can they connect to multiple panels to get 8T8R?

I don't understand the need for 3 antennas per sector. Even in a high capacity situation only two antennas would be required.

2 of the antennas are for pcs and 1 for 2500. We have setups like that here in new Orleans. The 2 panel pcs setup is being called the "high capacity" project. Pretty much every other site here is going to that.

That's a Nokia build near where I live. Old stuff on the ground after the install. Snuck up and got some pics.

Probably allow Sprint to fire up more Band 25 and 41 without adding more antennas.

Are the tri-band antennas cheaper than the 8T8R antennas? Is it possible to "chain" the antennas to get the same MIMO benefits?

 

Maybe it's more cost efficient. Plus, could this setup be more flexible for downtilt adjustments on a airlink basis not just frequency?

No. Yes but redundant. No. Not really.

Alcatel-Lucent markets run Rf combiners for high capacity sites. They don't use a separate antenna and pcs radio.

Verizon has some very good tower placement.

Is that six antennas per sector? Damn. I thought the typical four per sector they have here was a lot (most sites here can't handle more than that per rack) but wow.

Check out this setup.  2x 2.5 and 4x1.9.  High Capacity.  First site I have seen in San Diego with this type of setup.

That looks like two separate sectors. So 2 NV + 1 8T8R. A typical high capacity setup.

2 More towers I am wondering about. Any idea what these ones are?

 

 

If it does not match the spotting guides then it is not Sprint. See Alcatel-Lucent NV one and the pictures on the first post of the page and you will see your pictures do not match those of the spotting guides.

      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 4x40w 25 MHz PCS 1900 B25 RRUs (Panasonic) [old]

      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. 



      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!
