How to Spot Sprint Antennas and RRUs (Samsung)

Recommended Posts

Each provider (Sprint, ATT, VZW, T-Mo) has their own line of Fiber from a backhaul vendor. Some don't even share the same vendor.

They should, though.

Question regarding Samsung RRUs, are they mixed mode, as in a single RRU can do both PCS and SMR or are separate RRUs needed for the separate bands?

By mixed/dual mode they mean the RRU can do both CDMA and LTE (or WiMax and LTE in the case of 2.6 Ghz RRUs). So in Sprint's case, you have RRUs for PCS, 800SMR, and eventually BRS/EBS.

I'd say PCS/SMR and CDMA/LTE at the same time.  I.E. CDMA/LTE on PCS and CDMA/LTE on SMR on a single RRU.

On Samsung sites with both SMR and PCS, you usally see 2 RRU's per antenna, one for PCS and one for SMR. In the IBEZ you won't have any SMR RRUs of course, so on those sites you won't see a 2nd RRU. You also see SMR skipped on some sites in dense urban areas.

I need to make a closer visit to my new local site, when I drive by on the freeway I swear there is only 1 RRU. With the site spacing in West Michigan, they need SMR on basically every tower.

Confirmed only a single RRU, next visit I'll have my SLR and take pics to find out what is going on with this site.

Maybe you are in the IBEZ and Sprint can't put 800 up there yet?

Nope, about 50 miles west of it

Do you guys know what these are (marked by Red arrows)? There were guys working on my tower, then they left 3 days ago. This is what they added (3 total of them). I haven't seen this in other threads. I'm 99% sure that's where Sprint's equipment is located. This is in Madison, WI so a Samsung market.

Huh. How about that. There are 5 of them actually, it looks like. I'll go over to that thread to do some learnin.

 

Edit: are there other markets like this? Is this really an ATT rack? Strange. I'll get some closer pics tomorrow when the light is better and I have my DSLR. I want to see the bottoms of the antennas and the plugs.

That's a verizon setup. 

 

ATT's typical setups look like this

Is that second rack VZW? Third down is ATT? (pic from when they were working. Their truck had a Samsung rru antenna setup sitting in the back. That's why I thought it was Sprint for sure.)

 

There's a 4th rack that has like 2 pencil thin antennas on it that don't match anything I've seen.

Alright. I think I've clarified things today with better pictures.

Here's that Top Rack - not Sprint, look at antenna wire arrangement

Here's the whole tower

Here's where I believe NV will appear when they're ready (bottom rack), right there in the middle of the skinny ones. As I got real close to the tower, it's clear this is what's going on based on other towers I've stalked.

For the whole tower, top to bottom, I'd guess AT&T, VZW or USCC, T Mobile, then Sprint?

Ok, so let me get this straight... Both Ericsson and Alcatel-Lucent use 3 RRUs, and the Samsung setups only use two RRUs, correct? Also, what does RRU stand for? For some reason I feel like radio responder unit is the correct answer there.

Thanks! And as for the # of RRUs, Samsung has 2 while both Alcatel-Lucent and Ericsson have 3, right?

ALU has 2 RRUs with their new PCS model. Ericsson has 3 or 4 depending on if it's a high capacity site or not.

Ok thanks! I couldn't quite tell if the one ALU is 2 RRUs back to back, or 1 large one. Thanks for your help!

I was out getting some pics of this new site in SLC SL25XC135 which I believe is replacing another site due to construction. Anyways there is a antenna on it as well that is cone shaped would that be microwave? I thought NV is getting away from microwave? Its on the right?

Microwaves are usually rectangular and have a lot of buttons on the front. ;)

 

Yes that looks like microwave backhaul. WiMax markets have a lot of that on the WiMax gear.

very clever digi!! I thought it might be but as this site is a new site not a remodeled site I didn't think it would have microwave? So does that mean they will use microwave on some NV sites?

Approximately 10% of Network Vision sites will utilize microwave backhaul. If they can easily and cheaply get fiber to the site then they will but if not then microwave will work just fine.

      Ill make my comments brief, in hopes that it creates dialog abbot our future. The synergy and blending of the 2 company's from the network perspective is a complete disaster already! If you are a Sprint Network Employee and feel everything is so far, so good. You have not yet been tortured by the superior leader. Its coming. 
      T-mobile either has a leadership directive to force out Sprint employees, or the local markets and regions are overwhelmed by the extensive knowledge Sprint folks bring and that intimidation is causing them to try and force you out. To be fair, Sprint had layers of dead weight also and most need to be bounced. 
      From the brief time I have seen their processes and procedures combined with the lack of experience, rest assured you are all in for a wild ride.
      How about unionizing?

      Even though Sprint doesn't have the best coverage in my area. I do have lots of memories and nostalgia with the company. I wonder who else here will miss Sprint besides me?

      Its almost time for the next iteration of Samsung's Galaxy Phones! I'm planning on pre-ordering either the S20+ or Ultra. Current Rumors have it going on Pre-order February 11.  Let the discussion commence...

      I'm new to this forum, and I've seen people mention cell sites with specific ID's (for example, SF33XC664). Is there any significance to these ID's, and is there a way to decode them? Also, how do I figure out what the cell site ID's are for towers near me?
      Thanks! I'm excited to start talking on this site more 😀

    • I checked out your report; it all looks good, nothing to indicate that logging might not work. These logging glitches are very odd and difficult to reproduce across devices sometimes, and it drives me mad. As Robert mentioned before me, his Motorola had similar issues. I couldn't find anything wrong on my end but a couple of reboots did the trick. I have no idea how or why that would fix anything, but please give his suggestion a try and let me know..
    • I had this issue when I purchased a Moto Z2 Force.  I uploaded my log file immediately after activating and installing SCP from my previous phone.  Drove me nuts.  What I finally did to solve the problem...I had to disable the logger, reboot, re-enable the logger, reboot and then it worked. Robert
    • I think I have been experiencing that with low-numbered Verizon 1X IDs (I never connect to Verizon LTE). I assumed it was something on my end, but maybe it's related.. I'll have to try getting some specifics and monitor that thread.
    • Mike, I don't know if it's related to the beta or not, but I got a new Moto E5 Play for US Cellular and everything seemed to be good with it.  But I went on a several hour drive today, and when I got home, I found that the log had recorded nothing.  No updates on existing rows, and no new rows.  I checked and the logger is enabled, etc., and I've gone so far as to factory reset the phone and it's still not logging anything.  I sent you diagnostics in case you see something I don't.  I am able to import and export log databases without issue, but it doesn't seem to want to actually write anything to the internal one. - Trip
