I noticed this morning that SE52XC052 (near the intersection of the 522 and 405) is now a M-MIMO tower. Great find! Do you know if those sites are broadcasting NR yet?

I don't have a 5G phone, so I have no clue. I have seen sector IDs greater than 20 but not sure if that means anything besides the fact it is no longer triband. Interestingly, I can't find a permit for this change despite the fact the change is very recent. Quote Link to comment Share on other sites More sharing options...

That's why a lot of sites with KMW 16-port triband antennas have an inactive 8T8R next to them. Any chance you were able to snag some photos of the site? If not, the mast is relatively low, and you can probably get good photos from the parking lot of Cedar Park Christian School. Quote Link to comment Share on other sites More sharing options...

RAvirani Posted June 10, 2020 Share Posted June 10, 2020 The L2500 EARFCNs in the Seattle market were changed today. Before we had 40978/41176/41374; now we have 41094/41292/41490. I presume this is to make room for NR. 1 Quote Link to comment Share on other sites More sharing options...

Sent from my LG-LS998 using Tapatalk Actually more than that since Sprint/T-Mobile controls the entire 2.5Ghz block (all 194Mhz) for the entire metro Seattle region. This allows them to use the J and K guard bands as well, since they control the blocks around them in their entirety. The K guard band (2614-2618) in particular was why the B41 20Mhz channels started at 2628MHz (until yesterday). As such, that would leave 130MHz for 5G communication if they wanted. Relevant License Links:B413 - TDI Acquisition Sub, LLC (shell company of Clearwire)L000002361 - Clearwire Spectrum Holdings II (shell company of Clearwire)L000007381 - Clearwire Spectrum Holdings III (shell company of Clearwire)L000007382 - Clearwire Spectrum Holdings III (shell company of Clearwire)L000007383 - Clearwire Spectrum Holdings III (shell company of Clearwire)L000031135 - American Telecasting of Seattle - Sprint acquired this spectrum in 2018.

PedroDaGr8 Posted June 29, 2020 Share Posted June 29, 2020 Came across a strange small cell broadcasting on only low B41 EARCFNs. It's on top of the Overlake Sprint store in Redmond. At first I thought it was the tower right behind the store but that has the usual tri-band setup (which used to be on the Sears nearby). I nearly missed this antenna, it's a small white fully enclosed small sell. You have to be far from the sprint store to see it. It only has these two cells unlike the old clearwire sites. Not the first time I've seen these EARFCNs, they seem to be used a lot in the Georgetown district. Edit: Checking back, most of those in the Georgetown district are also small cells but at least one is on a regular tower. Not sure why the Georgetown district has so many of these.

That site is a temporary small cell until the tower behind it is turned on. It's LTE-relay backhauled. Small cells that are LTE-relay backhauled broadcast at 39874/40072. 1 Quote Link to comment Share on other sites More sharing options...

Sent from my SM-G988U1 using Tapatalk Went by there today and confirmed it is broadcasting 3x20MHz b41 carriers (2518.4MHz, 2538.2 MHz, and 2558.0 MHz), and a single n41 carrier (2588.4 MHz, BW: 40 MHz). That means all 100 MHz from that antenna is accounted for. The allocation is odd considering the nearby Sprint tower is still broadcasting 3xB41 (2640.4MHz, 2660.2MHz, and 2680.0MHz). That means there is technically 120MHz (our of 194MHz) allocated to B41 in that area, 40MHz n41. This leaves a gap of around 30Mhz in the middle and 12Mhz at the low end left unallocated.

PedroDaGr8 Posted September 23, 2020 Share Posted September 23, 2020 FYI I just drove past the main T-Mobile/Sprint Woodinville tower (near Target) and there were workmen on the T-Mobile rack. It looked like they were installing n41 panels. I'll confirm tomorrow. Sent from my SM-N986U using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

I'm unsurprised that n41 is going up on that site given T-Mobile has already deployed massive MIMO midband panels there. I'll try to stop by tomorrow as well!

PedroDaGr8 Posted October 14, 2020 Share Posted October 14, 2020 The powerline tower at Kirkland/Rose Hill (47.67565, -122.17482) got upgraded to n41 as well. I noticed n41 on the 405 in an area where I have never seen it before and eventually found the source (there aren't a lot of TMobile towers in that area). That tower location makes huge sense if they intend to keep Sprints 2.5GHz towers online (either as B41 or n41) because it is located in a gap in Sprints B41 coverage. Interestingly, it seems to be 60 MHz n41 BW, rather than 40MHz I saw at Canyon Park. I will go back in the next few days to check the n41 frequency and to see if it is broadcasting any T-Mobile B41.

Sent from my SM-N986U using Tapatalk Went by there today, it is broadcasting two 20MHz B41 carriers: 2538MHz and 2558MHz. The 60MHz n41 carrier is at 2597MHz. Tmobiles plan for the 2.5GHz spectrum makes far more sense now. Irrespective of bandwidth: 2508MHz to 2568MHz: TMobile B41 2568MHz to 2628MHz: TMobile n41 2630MHz to 2690MHz: Sprint B41. This gives them freedom to reallocate either B41 portion to make a contiguous 120MHz n41 allocation. 1 Quote Link to comment Share on other sites More sharing options...
