Network Vision/LTE - West Washington Market (Seattle/Puget Sound Region)

That's interesting. Out of curiosity, why is VZW broadcasting B25 LTE via MFBI?

Unsure - but it’s definitely live. B2 shows up about as often as B25.

I did not realize that other carriers used so much 5x5.  B26 is not as out of place as I thought, even at 3x3.

Yes, but AT&T and Verizon have 5x5 lowband on top of 10x10 lowband, often aggregated together, providing effectively a 15x10 or 15x5 pipe. And T-Mobile’s 5x5 B12 is old news...

Here's a quick summary of the competitive landscape post spectrum swaps in the greater Seattle area:

AT&T:
- 10x10 B12/17
- 5 MHz B29
- 5x5 B5
- 20x20 B2
- 10x10 B30

Verizon:
- 10x10 B13
- 5x5 B5
- 20x20 B4
- 10x10 B2/25 (MFBI is live across the market)

Sprint:
- 3x3 B26
- 10x10 (soon to be 15x15) B25
- 60MHz B41

T-Mobile:
- 5x5 B12
- 20x20 B4
-10x10 B2

Any pics of signal check with VZW showing that?

It's on the Doubletree Hotel roof, just south of Southcenter Mall.  I found that site a few weeks ago.  It's shown on the B26 update map.  Thanks for the report. :tu:

The tower that serves my old store... it’s all grown up now

Noticed something interesting as I opened up Field Test while driving through Seattle last night - there are 7 B41 carriers live throughout the city. 

I saw EARFCNS 40072, 40270, 40582, 40780, 40978, 41176 and 41374. 

Before I had only seen 40978, 41176 and 41374. 

More investigation is definitely needed...

That means small cells. Small cells broadcast different EARCFN numbers than macros do.

Small cells in Seattle broadcast on 40072 and 40270. The thing is, I’ve also encountered macros that broadcast on those frequencies...so I definitely need to investigate a little more.

Yeah there are 2 sets of 2 contiguous carriers below the 3 contiguous macro carriers. So some could be fiber fed small cells (otherwise they'd be limited to 1 carrier), or they're starting deployment of 4th and 5th carriers on macros.

 

We need someone with SCP and earfcn logging to see what shows up.

You're probably seeing just different sites using different contiguous carriers. It's the same thing in SLC. Part of the metro uses B41H while other parts of it uses B41L.

 

I have several sites here that operate B41L while the vast majority operates B41H.

I have been seeing B26 up in Lynnwood for the past week or so. Glad they're finally making it closer to the border.

Is that 3x3 or 5x5?

It will all be 3x3 in Western Washington.  I am working on an internal map based on some source info I have seen recently.

Ok, so driving through Seattle again today, I was able to confirm that several 8T8R sites are broadcasting EARFCNs: 40072, 40270, 40978, 41176, 41374. Thats 5 carriers with a possible (but unconfirmed) 6th at 39874 (as I have seen that EARFCN in Seattle before). 

Maybe 8T8Rs are now broadcasting 6 carriers and small cells are using EARFCNs 40582 and 40780?

What are the GCI of the cells?

If it's 4/5/6 then it'll be sequential 0C/0D/0E and onwards.

Small cells (Airspan) will be 01 and then 04(?).

I didn't grab Field Test screenshots yesterday but I'll try to go back later this week and do so.

Here are a few Field Test screenshots from the 8T8R that’s broadcasting 6 carriers. I’ll head back tomorrow to grab more.

Nice. That's the 4th carriers based on GCI indicators of 0C and 0E but the 40270 with GCI of 08 is a bit weird.

Usually 00-02 is 1st, 03-05 is 2nd, and 06-08 is third for an 8t8r three carrier chain. Interesting.. Try and grab more of the GCIs if you can.

Will do today. I was driving past the site at 60 mph in a car so that’s all I was able to grab last time.

Where are you grabbing them? I work downtown and I can try to grab some if you'd like.

The site I’ve been getting screenshots from is at the Montlake Blvd NE exit off 520. 

There are a few other sites in downtown Seattle that are broadcasting six carriers.

      Here are the Alcatel-Lucent (ALU) Network Vision equipment for Sprint. Their equipment consists of 2x base stations, 6 or 9 Remote Radio Unit (RRU) setups, and 1 standard NV antenna of with connectors on the bottom (4x PCS, 2x SMR). 

      Below are images of Alcatel-Lucent equipment. In these images, you will find Alcatel-Lucent base stations, Sprint Network Vision antennas, PCS 1900 & SMR 800 RRUs, and their configurations.
      Alcatel-Lucent 4x40w 25 MHz PCS 1900 B25 RRUs (Panasonic) [old]

      Alcatel-Lucent  4x45w 1900 MHz B25 RRU 

      ALU 2x50w B26 800 MHz RRU [KMW Communications]

      Older Panasonic Setup [4x40w 25 MHz B25]




      Standard Alcatel-Lucent Setup 
      Utilizes 2x50w 800 MHz B26 RRU and 4x45w 1900 MHz B25 RRU and compatible antennas. 



      Closer Look at the connectors on the bottom of the antennas

      Special Case Mexican IBEZ Setup
      Note the lack of 800 MHz RRUs though the antennas are capable of 800 MHz. 


      High Capacity Setup


      High Capacity no SMR 800 IBEZ setup

      I notice a lot of post regarding the markets in IL,FL,TX,PA,NYC.... but how about about the Los Angeles market? I THINK it was samsung doing the set up for the L.A market? Not sure though.... I'm not a sponsor member of the site so I can't really check... if I had a job I'd most definitely donate!
       
      Couple of months ago the local towers were all down and being upgraded to NV I assume since Larry from Howard forums said there was NV work being done my zip code. The speeds were better for a bit but now they are awful again.
       
      Can anyone (most preferred Robert) make a comment on if there is any LTE activity near 90255 area code?
       
      Thanks, great site by the way... I'm a Lurker.

      I'm here looking for answers to a simple question. Where is this mystery Sprint signal coming from? For the past few weeks I've received a signal on multiple Sprint devices, two Sprint devices with roaming turned off, and two Virgin Mobile phones and Virgin Mobile phones can't roam, the other rate plans might be able but I'm talk about Virgin Mobile devices from before they introduced all those other plans. What I'm making clear is these devices have to be picking up a Sprint signal, plus I've downloaded the SignalCheck Pro app which has indicated two different signals 1XRTT and 1X800. 
       
      The signal only last for about 8 hours each morning and begins coming in and out towards the end of each morning. I try making a call and it fails, and it doesn't get any data at all. I try each device and they all do the same thing they have a signal and very strong signal with no data, and voice doesn't go threw, I haven't tried sending a text figured no data, no voice then there must be no text.
       
      I read about some "projects"  that Sprint has going on Project Ocean and Project Cedar. Since Project Ocean is suppose to be taking place in Missouri and I live so close to the Iowa, Missouri line, I figured if there is a tower going up maybe it is possible I'm getting a signal from it, in the early stages. I really don't know what is going on, if Sprint is launching service, putting up new towers and that signal finally comes, and stays, and works. I'll be back full time on the Sprint ban wagon. Unfortunately, I live in an area not served by (according to experience and coverage map) Verizon, AT&T, T-Mobile and Sprint. Not even the two Iowa carriers i Wireless or Chat Mobility serve my area, go 10, 15 or 20 miles in any direction your good, here, wireless dead zone, no choice of carriers. And if Sprint puts a tower here if I finally get an answer and learn that signal will soon come and stay and work I'll finally have a choice.
       
      So if anyone has any ideas, has experienced this in other parts of the country or has any idea what could be going on please say. Any information is better than not knowing, and together maybe this will be answered.
