Sprint TD-LTE 2500/2600mhz Discussion


Recommended Posts

Wow...pretty decent signal for a "basement". Can't wait to see what results you get today with the USB to Laptop connection.

It was a basement, but the site is on the roof of the building. In my room, I can't seem to get above 43Mbps DL/18Mbps UL. However, I'm underneath the panels here. Maybe I should try the balcony? If that doesn't work, I'll walk a few blocks and get in front of the panels...unless I can get on the roof. ;)

Question:

 

Did you try connecting both your laptop and the Note and perform a speedtest at the same time? I was just wondering if 2600 might be throttled. Sorry if this was covered before in the thread...its really long!

OK...In my hotel room using my Netgear Zing 771S USB tethered to my laptop, bypassing the WiFi, this is the best result I got on Download...

It peaked around 56Mbps, then steadily dropped until it stopped at 47Mbps at the conclusion of the test.

In contrast, my Note 2 got this:

So I believe my Note 2 is getting a lot of WiFI interference from several competing WiFi signals in my hotel.  Using the laptop tethered directly to the MiFi is the way to go.

 

So far if you cherry pick the best test result items, here is what I've encountered USB tethered to laptop:

 

Best Download speed:  56Mbps peak, 47Mbps completed test

Best Upload speed:  18Mbps

Best ping:  58ms  

 

So far the best test result using the Note 2 on WiFi:  

Best Download speed:  36Mbps

Best Upload speed: 20Mbps

Best ping:  88ms

Did you figure out if that hotspot can do more than one spatial stream on the wifi yet?

 

I think with the all the WiFi pollution in my current location, switching to WiFi will result in lesser speeds.  Even if it is dual stream.  So it will not be conclusive here.  When I take this testing mobile later, I'll give it a whirl.

Moving the testing out to the balcony.

Robert, your EARFCN 40978 indicates a 2628.8 MHz center frequency, putting this TDD carrier in BRS blocks.  As you move around among sites and sectors, keep a log of your EARFCNs.  Let us see if it changes.

I'm curious if he is keeping track of the cell IDs as well.  Those look like decimal style global cell identity numbers.

I'm thinking these hotspots only do 1x1 on the wifi side, just a wireless nerd being curious if they can do 2x2 wifi.  I have used 2x2 in a heavy wifi environment and being close to the router still allowed for the 130+ handshake indicated on the laptop.

So far, every site I've connected to has been 40978. I'm keeping track of everything. I will definitely post any differences I come across.

We got severely delayed by a car accident/construction mess in Colorado Springs. We are checked into the hotel and my wife and I are even have a drink together for the first time in years.

 

Down in the basement lounge here I'm still getting a respectable TD-LTE 2600 signal and good speeds.

More testing later...in the morning.

Definitely. I will be updating them on the Premier Sponsor TD-LTE site map.

Best final result so far inside the hotel. We are now calling the valet for our car and about to go mobile. I have had to switch to the 12GB hotspot plan for the remainder of this billing period. I'm burning through the GB's! AJ is twitching. :)

 

Robert

 

EDIT:  Got one even slightly better:

Yep, you are definitely giving me the heebie-GBs.

This is the best Band 25 test from my hotel.  Seeing how the nearest site is approx 8 miles away, that's not bad at all.  -113dBm RSRP, Cell ID 138486529.

I guess the bed doesn't have red silk sheets and rotates either then.

Incredible!  8 Miles away & inside!  Holy Sheet! and at -113dBm!

That Zing seems to have quite the 1900 antenna in it, 8 miles away. The MiFi 500 is having trouble getting a site 2 miles away. Mind you, there's nothing but dirt and trees and rock in the way, instead of clear atmosphere...

 

Do you think the reason you haven't gotten above ~50 Mbps is backhaul?

 

In other news, the MiFi 500's lte_available file is anything but plaintext... No idea how to read it. I'll post it if anyone's interested.

No, Mr. J.W. Marriott was quite a prude.  ;)

There is a new Band 25 LTE site in Thornton, adjacent to some Clearwire TD-LTE 2600 sites.  I'm going to see if I can do some hand off testing.

Yes.  Then, meanwhile back at the Herron compound in New Mexico...

Okay, from a band plan perspective, here is what we are looking at for the TD-LTE carrier in Denver.  It is located right at the low end of the contiguous 55.5 MHz of BRS spectrum that is counted as part of the spectrum screen.

Please Youtube any speeds over 70Mbps.  Don't want John Legere to say we had Photoshop the speed test.  ;)

    • 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.
