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.

10x10 or 2nd carrier is dependent on local spectrum holdings, hardware should be fine.

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.

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.

I beg to differ, we have a gmo in the Cincinnati market that definitely is broadcasting 10x10

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.

It does support it, not should.

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?

 

:pinch:

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.

Please show these to your engineer and ask him how.

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?

      Network Vision/LTE - New York City Market

      Was true in my market. Likely means a higher percentage of 5g phones in your market.

      Network Vision/LTE - New York City Market

      By Paynefanbro · Posted

      Unable to confirm if it's really off but I noticed this morning that I'm no longer connecting to Band 41 on my home site. Switching my phone to LTE-only pretty much always put me on Band 41 since it was the least used band on T-Mobile's network. Now I'm only able to connect to Band 2/66. Not complaining because it means speeds are faster on LTE and maybe 150MHz n41 is around the corner.

      Dish Network/Boost Mobile cell/5G buildout thread

      Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.
