mirskyc Posted September 1, 2016 Share Posted September 1, 2016 any one know if GMO sites able to do 10x10 or even a 2nd carrier or does it all depend on the equipment? Quote Link to comment Share on other sites More sharing options...
payturr Posted September 1, 2016 Share Posted September 1, 2016 any one know if GMO sites able to do 10x10 or even a 2nd carrier or does it all depend on the equipment?The radios could do it, I believe GMOs get new cabinets so it should support new network cards, I don't know about the panels though.

Dkoellerwx Posted September 1, 2016 Share Posted September 1, 2016 Is Sprint not using Mobilitie for NYC? Both of those names are in house employees. These are mini macro conversions. So it would make sense to have Sprint's guy's handle this. Clear site conversions, so no these are not Mobilite. They were already in place. Mobilite will be doing the new sites that come next. The radios could do it, I believe GMOs get new cabinets so it should support new network cards, I don't know about the panels though. We have a number of GMO LTE sites around in Missouri and Kansas, none of them have a second carrier. The same goes for the few GMO LTE sites that have gone live in the Samsung market of Nebraska/Iowa. Every other full build site has the second carrier live, and has had it for several months, but the GMOs do not. So far the evidence says GMOs will not have the second carrier.

GMOs cannot do a second carrier or 10x10 in Samsung markets. Confirmed by a Samsung engineer. Quote Link to comment Share on other sites More sharing options...

Deval Posted September 2, 2016 Share Posted September 2, 2016 If I'm not mistaken, a GMO site has updated base stations and the RRU mounted next to the base station, rather than up near the antenna panel. If so, as long as the panel has 2T2R ports for 1.9, and the proper card is in the BTS, it should support 10x10 LTE. 1 Quote Link to comment Share on other sites More sharing options...

If we can get our GMOs to 10x10 it would make life a lot better in Seattle. 1 Quote Link to comment Share on other sites More sharing options...

It's a NV site with the radios on the ground. GMOs use coax lines and original legacy CDMA panels. Quote Link to comment Share on other sites More sharing options...

No, that IS a GMO site. Note the legacy antennas. All GMO sites have radios on the ground. Hence the name Ground Mount Option. 1 Quote Link to comment Share on other sites More sharing options...
Dkoellerwx Posted September 3, 2016 Share Posted September 3, 2016 On another note... I'm thinking we should move this discussion to the GMO thread? I think I may do that as soon as I'm done with work. 4 Quote Link to comment Share on other sites More sharing options...
caspar347 Posted September 3, 2016 Share Posted September 3, 2016 Maybe I'm missing something obvious but it looks like nothing's connected to the output ports on those RF combiners. Quote Link to comment Share on other sites More sharing options...
caspar347 Posted September 3, 2016 Share Posted September 3, 2016 Actually, it looks like there are only two lines going out of the RRUs. So why are there four input lines on those combiners?Edit: it just occurred to me that they may be using the combiners as splice points for the old coax to new coax. Is that a thing that happens? http://s4gru.com/index.php?/topic/7581-gmo-site-discussion-ground-mount-option/?p=488451 Quote Link to comment Share on other sites More sharing options...
RAvirani Posted September 4, 2016 Share Posted September 4, 2016 According to my engineer, most GMOs in Seattle use RF combiners which limit the B25 bandwidth to 5x5. Quote Link to comment Share on other sites More sharing options...
lilotimz Posted September 4, 2016 Share Posted September 4, 2016 According to my engineer, most GMOs in Seattle use RF combiners which limit the B25 bandwidth to 5x5. Yep. Observe nowherelaters GMO site setup. Notice those RF combiners were bypassed and they ran the coax directly into the RRUs. 2 Quote Link to comment Share on other sites More sharing options...

Notice those RF combiners were bypassed and they ran the coax directly into the RRUs. So I just looked real closely and realized the combiners aren't connected to anything. I feel dumb now. So to clarify, some RRUs can do MIMO LTE+CDMA over just two coax lines? Quote Link to comment Share on other sites More sharing options...

caspar347 Posted September 5, 2016 Share Posted September 5, 2016 SISO / SIMO So I'm guessing they go back and bypass the splitters combiners (d'oh) in 10x10 markets? Quote Link to comment Share on other sites More sharing options...
