Network Vision/LTE - Washington DC Market

Walked into work this morning after a week and a half off and instead of sitting on B25 from the very strong B25 signal I get here these days, now I'm sitting on a new Sprint B41 signal.  Sector is 33 (GCI is 0x0317F933), suggesting I'm looking at a west-facing panel but I can't tell, for the life of me, where it's coming from.  I didn't have a corresponding B25 or B26 in my database for it, so I'm quite stumped.  It has to be pretty close since if I walk to the window, I get to about -95 dBm. 

 

When I leave today I'll see if I can determine where it might be coming from.  I was thinking that the B25 I started getting was from the adjacent building, but now I'm thinking it's this building (which would explain the -78 dBm or so I usually see, and I note a building permit on this building was approved in April though I can't tell for sure if it's Sprint).  I'm also thinking this B41 I'm seeing is from the adjacent building, but I am east of said building, unless the 33 is just pointed oddly.

Just a suggestion...if you have Signal Check, try switching your phone to CDMA/3G only, then open the Signal Check app, and you should see an address that is clickable, and should launch Google Maps. Even though the addresses broadcast by the cell towers are usually not completely accurate, it should at least give you some idea where the cell tower is located.

Looks like my local clearwire tower is finally being prepped for conversion! Working on a clearer picture, but permit information is below.

Sprint proposes to remove their existing 12 antennas on penthouse wall and replace with 6 new antennas of similar size and weight. All replacement antennas are to be installed on existing Sprint mounting locations that will become vacant once the existing 12 antennas are removed.

Is that a Sprint/Clear colocation site?

I don't believe it is a legacy Sprint site, but it did host Nextel. My legacy Sprint tower (Site ID: WA57XC011)

is about 1500 feet southwest at 1120 Vermont Ave NW. That site finally got B25 a few months ago. I assume since it is a nondescript federal office building that slowed things down.

Remember when Frederick was a black hole of 3G? Woof.

Yes. I remember!! I remember only getting unusable 3G or 1x, now I pretty much get LTE almost everywhere I go (Band 25 and 26) and solid 3G and now Spark in that one area

I have noticed that I am on LTE most of the time in the entire DC/NoVA/MD area.

 

There are only a few locations where I drop to 3G.

 

Even in buildings, I am generally getting LTE, and 800 in basements and underground garages.

I've been seeing B41 second carrier in this area for months on certain sites.  The Clear sites have had it for a few months, while the Sprint 8T8R sites have been popping up over the past several weeks.

Clear sites are those inherited from Sprint's purchase of Clearwire, and implemented using the Clearwire B41 equipment.  Sprint sites are those with newly installed Sprint B41 equipment.  When you use SignalCheck or SignalCheck Pro, it will identify each site as either a Clear or Sprint site.

So I just thought I'd mention that while at a bar in Ocean City MD, Signal Check told me that I was connected to B41 Sprint LTE 2500, and the data was completely unable. I'm not talking about slow speeds, I'm talking about completely unusable data. Tapatalk wouldn't work, an email I sent wouldn't go through, and a text I sent wouldn't go through.

 

I actually had to manually switch my Nexus 6 to 3G only. I can see why some people get pissed off at Sprint. If I didn't know how to manually switch my phone to 3G,I'd be pissed off that my data wouldn't work.

 

UPDATE...I took a shot at putting my phone back to LTE mode. It reconnected to B41 Sprint LTE 2500, and for now, it seems to be working. The only difference is that there seem to be a few less people in the bar now, so that may be the difference.

I highly doubt B41 was congested to the point of having no data at all. Sounds like the cell site might've just had a temporary issue or your signal was just extremely weak.

I bet your signal was just too weak. I've experienced that in the past and it started up again with the last S6e update. While I love B41, I wish my phone would better recognize that the signal is too weak and search for B25/B26.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
