mhammett Posted September 13, 2013 Share Posted September 13, 2013 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. Sent from my EVO using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
jefbal99 Posted September 17, 2013 Share Posted September 17, 2013 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? Quote Link to comment Share on other sites More sharing options...
mozamcrew Posted September 17, 2013 Share Posted September 17, 2013 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.

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. Quote Link to comment Share on other sites More sharing options...

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.

mmark27 Posted October 11, 2013 Share Posted October 11, 2013 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.

mmark27 Posted October 11, 2013 Share Posted October 11, 2013 Ericsson RRUS11. 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. Sent from my SPH-L720 using Tapatalk 4 Quote Link to comment Share on other sites More sharing options...

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.

mmark27 Posted October 12, 2013 Share Posted October 12, 2013 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?

apphysics Posted October 20, 2013 Share Posted October 20, 2013 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. Quote Link to comment Share on other sites More sharing options...

apphysics Posted October 20, 2013 Share Posted October 20, 2013 Remote Radio Heads / Remote Radio Units Thanks! And as for the # of RRUs, Samsung has 2 while both Alcatel-Lucent and Ericsson have 3, right? Quote Link to comment Share on other sites More sharing options...

bosox801 Posted November 22, 2013 Share Posted November 22, 2013 lilotimz 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.

Sent from my SPH-L900 using Tapatalk 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. Quote Link to comment Share on other sites More sharing options...
