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.

      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!

      Some history first;
      Been through all the highs & broken promise Lows over the last 18 years with Sprint, currently have 7 lines. My main areas of concern are where I live and my retirement cabin which are in a semi Sprint dead zones.
      My Note3 will hold onto 3g for dear life. I have to toggle airplane mode to return to LTE signal (while standing in my back yard). Once I enter the house it drops to 3g. Speed test at 4g is slow at best.
      In my front yard it's 3g unless I walk into the center of the street, togle airplane mode then can pick up SLOW 4g again(until I walk to my front door.) i know note3 is missing band 41 which is suposto help.
      The wife's Iphone6 is 3g in my front yard, lte in the middle of the street and drops to 3g when entering our house also. When on 3g and walking into the back yard, airplane mode to froce it to 4g and it sticks to lte once you enter the house again. 1 to 2 bars, 17mb down with 1.3mb up. It will hold onto the lte signal.
      Does anyone have any insight to what I should expect with a Note5? Sprint has programed the system so if our 3g signal is stronger, my phone will want to stay there, Will carrier aggregation solve this problem or will the Note 5 try and hang onto the stronger 3g signal at all costs?
      I'm able to pre order the Note5 for $249 with a $200 SAMSUNG REBATE. Hate to get all excited and sign on for another 2 years if the Note5 will be doing what the note3 is doing. I get the whole ehrpd and 3g improving the cell phone experiance. At this point im more interested in being able to use more than the 5mb per month my 7 phones average and finally be able to use some of the unlimited data I've been paying for over the last 18 years. I'm in West Orange County, CA. and travel to the SAN Bernardino mountains weekly. Experts please chime in. On the fence to switch carriers but want Sprint to suceed and be there when they do!
    • By derrph
      I'm sure everyone remembers the free night and weekend minutes we had years ago. This morning I was thinking what if a carrier took that same idea but instead made for it data. I think that if a carrier was able to implement this that it would be big and a game changer. What do you guys think?
