How to Spot Sprint 8T8R TD-LTE RRHs (Nokia Networks)

Why do they install the equipment, but it doesn't go live for a few months?

Different crews, backup upgrades, waiting for detailed setup instructions from fit testing which is now complete.

sorry if this has been asked but i was reading another topic and skimmed across an entry. Is it true that an 8t8r panel has double the capacity with a single 20mhz channel? 

 

Basically yes due to the fact a 20 mhz TDD-LTE carrier in Sprints configuration will top out at 80-90 mbps whereas Sprints 5x5 mhz FDD-LTE carrier tops out at ~37 mbps in the best of conditions.

And now for something completely different.

In size/weight-constrained spots (namely stealth sites), Sprint is actually ripping out original NV equipment and installing these new antennas, the CommScope DHHTT65B-3XR, with an RRUS 31 B25 and an NSN RRH alongside the original RRUS 11 B26.

So is it safe to say that band 41 will be coming to more sites than expected with these new panels and RRUs.

Has this actually happened anywhere?

More than expected? No, Band 41 is still expected to be added to the vast majority of Sprint sites.

San Francisco is full of them and there's a few in my market, a few in Phoenix, and a few elsewhere too. 

 

They relocate the 800 RRU to a ground mount setup sometimes.

So these same antennas are being used in different markets? 

 

How many Band 41 carriers are they capable of?

4x 2.5 rf ports = 3 carriers max unless they they have a RF Combiner for 2.6 then they can do 6 carriers as per a typical 8T8R setup by combining the 8x 2.5 jumpers from RRU to a combiner that outputs 4. A combiner does have some drawbacks in terms of signal loss though.

I could see these used in some GMO conversions as well, especially lattice/truss sites. Wood utility poles seem to be able to handle the full weight of a regular 800 1900 2500 LTE setup for at least two sectors based on observations (at least so far).

Gmo conversions, yes please!

please correct me if im wrong. 8t8r is basically 8x8 mimo but no device can take advantage of that high order at the moment. so basically it splits it the antennas in half for 2 4x4 or 4x2?

Yes. They're running it in 4x2 MIMO configuration.

I noticed a tower being upgraded near me and I would assume it is for B41.  The tower currently has B25/26 on it.  However, I am not 100% sure this is a Clearwire/Sprint upgrade.  Based on this forum, the B41 antennas are supposed to be smaller than the Sprint B25/26 antenna, however, from the link below the Clearwire B41 antenna are a little longer.  The circles in red are the new antenna, and the circle in green are the Sprint B25/26 antenna.  Are the one's in red Clearwire B41, or are they for another carrier?

Those appear to be 8t8r antennas, not Clearwire.

Can someone tell me what this is what carrier because that was just put up not too long ago

That’s s really bad photo...can you get a closer/higher res one?

Unfortunately I can't for the meantime I am banned from the property for one year

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
