Poor LTE speeds at FLL


Recommended Posts

I was at Ft. Lauderdale airport today and got results of 400kbps with 4G and an RSRP in the low 90s. Just wondering why this would happen. I've attached my screenshots to illustrate.

Did you try another speed test server?

There is a site in Tulsa that usually fails to transfer any data regardless of signal strength on one of its sectors. You can see -70dbm signal get 2000+ms ping, then maybe 10kbps down and failed upload on LTE. The worst part is the messed up sector covers a huge area along a major highway and makes any Sprint phone that connects to it unusable.

 

When they launch Tulsa, I'm going to raise hell on that one.

Yeah at night LTE is bad at the tower at north wood university. Good signal but only like 900 Kbps download. Can someone explain why the download speed test runs with poor signal but I can't get the upload to run. I'm in west palm beach with galaxy s4

There is likely a problem with the site. Since West Palm is a launched area, call Sprint and open a ticket. Just make sure you actually have a good signal. The S4 doesn't show LTE signal strength in its bars. See the link below for an explanation:

If your signal is actually weak, then I wouldn't report it. It will get better when a closer site launches. If the signal is actually strong, then call Sprint.

I use signalcheck lite to check the LTE signal. I guess I will call them at night when I'm close to that tower.

 

What is your LTE RSRP?

The signal was around -90 but I know it was less than -100. So I don't know what to say. Can you give me some information on a different tower ?

No, but the internet was virtually unusable. It took close to 2 minutes to load Google's webpage so I'm pretty sure the results were accurate. There was another test I ran (same server) that was like 30kbps for download with a 450ms ping but it then stalled out. All internet was very slow, not just the tests.

I've ran into this same issue with one tower here in Sunrise, FL. It appears one sector of this tower no matter how close you are to it provides inconsistent data.

Although it is common to have one sector here or one site there to have problems during deployment, it seems that the Miami market has more than its share. Wow.

 

If they do not get corrected when each area launches, I suggest opening tickets.

Not to go too far off subject, but LTE coverage is quite spotty in nearby Port St. Lucie, which I believe has launched. I am aware that there are still towers yet to be upgraded, but even around the towers that have been, the radius of coverage seems rather minimal. Is this something that you would suggest calling to open tickets on?

No, definitely not. Communities launch typically with 40% of sites being completed. Opening tickets about other sites not yet being completed (spotty coverage) is a waste of your time and Sprints. The other sites will be ready as soon as their ready. Good question.

I don't think that would be recommended, as they are lighting up new towers daily in the markets. Basically work still goes on, just has a "blanket" coverage.

Got it. Thank you, Robert. I guess it seems like the upgraded towers should be able to reach the area I'm driving through, but maybe the issue is that a legacy tower is better situated (or configured) to cover that area.

Well, looking at Sensorly and at my own experiences, I really wouldn't call Port St. Lucie's coverage a "blanket." Maybe you could say the Turnpike is somewhat well covered through the city.

 

Nearby Palm City and Stuart are doing pretty well, though, I have to say.

They design cells to overlap only slightly. If they overlap too much, it will cause interference problems. So places where sites have not been upgraded will have poor to no coverage.

I have found that u get slower speeds at airports with sprint 4g, as far as I know sprint hasn't upgraded the das at all airports it has, so the 4g you are getting is from towers near by. So it will be slower with all the users. I know in time, sprint with get to it. That is also something that after they buy clear, that will get better too :-)

I was told on Wednesday that a site near the airport was reported as having "under performing" so that may have been related to your network issues at the time. I only know this due to me having a open ticket with Sprint in regards to an issue with 1 line on my account. The escalation manager pulled up a chart of all of the towers I was connected within the past week. I have always had good data speeds by FLL Airport since the tower across 595 was upgraded.

It looks like someone called sprint and submitted a ticket and they said the issue will be fixed by sunday. So we will see

    • Did my drive from PHX to SEA & got to experience the terribleness that is the totem lake area. Impressive, speed test didn't complete either time.
    • Weird that they'd go back to the Edge+. Would think they'd let folks use the S22 just like with Genesis. In other news, St. Louis has 10x10 n71 + n66 SDL live. A bit more info here:  
    • Wonder what other spectrum the auto industry can use, how much of the 5.9GHz was being used, and if 30MHz will be enough 20 or 30 years from now. The auto industry has had it for 20 years sure, but technology can move really slow.  It isn't good.  It isn't ready for real world applications. The hardware is too slow to be able to process enough reliable data. It is too expensive.  Etc. I would argue that we are just getting to the point where features that I would assume could use 5.9GHz are just now hitting mass market as the code is better, hardware is not only significantly faster but also cheaper. The baseline trim models still lack a lot of safety features but the next trim up usually comes with a bunch of goodies I'd assume could make use of 5.9GHz. Just imagine where we were in 2005, 2010, 2015.  Mostly just assumptions without enough knowledge of the spectrum use, so a hint of skepticism. With the what, 1.2GHz that opened up in the 6GHz range, getting 45MHz out of 5.9GHz is very meh.
    • Cool find! Been there since 2018 according to Cellmapper. The only other time I've seen them leave up a temp site like this for a long period of time was when a nearby site is temporarily inoperable like the one in Red Hook Houses. That doesn't seem to be the case here and it's pretty much a GMO site at this point. My best guess is that T-Mobile wanted to put a site there to fill in coverage but because it's on LGA's grounds getting the actual permission to do so is extremely complex so they worked out a deal with the Port Authority to put up a COW in the meantime.  
    • Would this be a T-Mobile COW outside LGA Terminal A? eNB 49106 seems to line up to its position, plus the arm for the trailer to hook onto a truck says T-Mobile. Here is the NYC streetcar view the image was pulled from.     For all the years I have been monitoring the DAS, I have never gotten -55 or better, even after passing by every antenna in a station that is deep enough to have 0 outside macros reaching in. The SNR is still 20+, so its probably designed that way on purpose.
