    And it did change: Does Robert ever actually sleep??

    Updated to 2.09 this morning. The app promptly crashed on startup. My GS3 was getting 4G at the time -- I am right at the edge of 4G where I live, and it flickers in and out -- so I went to airplane mode and restarted. The app ran fine, showed blank bars for GSM (!! - I have a CDMA phone) and Wi-Fi, but showed a filled-in bar for LTE with RSSI -87, RSRP -118 (told you I was fringe). Exited airplane mode, app crashed. In a couple of minutes, my 4G dropped out, I restarted the app, and it ran fine. The next time 4G dropped back in, the app crashed. [irrelevant aside: I don't know which is more frustrating: Living on the edge of 4G for 2 months while the Samsung contractors do other things instead of upgrading my local cell, or having a GS3 and playing with the Server Cell parameter trying to figure out which tower(s) I actually connect with, because I can't get to the cell ID parameter which shows the physical ID. (BTW, and also not actually relevant to this thread, but for those who understand LTE cell identifications: The sector ID's appear to not always be exactly offset by 169, at least where I am. There are only about 4, maybe 5, LTE cells detectable near me, yet I am getting about 8 or 9 variants of Server Cell on my GS3 debug screen, and some only vary by values of 3 or 4 or 5 from cell id's that I have previously seen. The parameter description in the API documentation seems to document some leeway in this regard.)] Back on topic: Please keep trying. I know it's hard to debug for the GS3 when you don't have one.

    Sadly, no. It has been requested.

    That sounds easy . . .

    Lite version: Sent you a crash report: I get 4gLTE only intermittently on my stock JB 4.1.1 GS3, and when I do, the app consistently crashes. Seems OK when LTE is not present. Now if Samsung would only update to a release that allowed access to the Sector ID info . . . And, thanks for this, it will be very useful.

    If you were a sponsor, you would see that there are current Network Vision/LTE installations going on in Hannibal, in and near Columbia, and also multiple sites actually in St. Louis. Based on my experience in Chicagoland, once the installations have begun (as they have for you), the progress has been rapid and comprehensive. Chicagoland was totally dark in late August, and as of today more than half of all Sprint sites in the region have LTE. I took the train northwest from downtown Chicago today, and got virtually non-stop usable LTE for over 40 miles. Pretty good progress in just over 4 months. So, don't be too hasty in switching. If you are, you may miss a huge improvement in your cellular experience.

    Or, you may be a victim of the dreaded "EVO LTE New Market Curse", where the EVO doesn't reliably transition from 3G to 4G in areas where 4G-enabled towers are not densely populated. The Irma Tower being the only Sprint LTE cell in just about forever, your phone simply may not have made the switch, and you would have needed to perform the increasingly popular and exciting "Airplane Mode Dance" to actually see the 4G (especially exciting if you are driving an 18-wheeler near the speed limit [of course you are driving near the speed limit, no respectable S4GRU-er would drive OVER the speed limit!] on I-39). Drat! I have this irrational, possibly insane , urge to see some purple, centered on that darned Irma Tower, which is especially weird because I live hundreds of miles away, in a region with lots of 4G LTE (and also lots of places where there ain't no 4G LTE, even where you are surrounded by it), and there is no earthly reason why I should even remotely care. Oh, well: C'MON IRMA!!!! FIRE UP THAT LTE!!!

    What is the app supposed to display? On a stock Jelly Bean GS3 I get only an empty screen, with the title "Signal Detector" and 2 small bars at the bottom labeled "Cancel" and "Submit". "Cancel" . . . cancels. "Submit" doesn't do anything. Have I loaded it incorrectly? Is my GS3 simply incompatible with the app? Have I missed something critical? Thanks, both for posting the app, and for your answer when it comes.
  9. tommym65
    And map it on Sensorly, if you can.
  10. tommym65
    This also happened to me after my last Sensorly upgrade, about 3 or 4 days ago. Seems to be a bug in the release.
  11. tommym65
    Too many acronyms. Does the Sector Cell ID show up anywhere on the GS3 engineering screens? The GS3 Serving Cell appears to be the Physical Cell ID, not the Sector Cell ID. Later: Actually you answered this on Dec. 20 in another thread: No. Oh, well.
  12. tommym65
    Boomerbubba: Thanks for your reply, it seriously helps my understanding. I should have been clearer in my post that I knew that BSLAT & BSLON were for the 1X transmitter, not LTE. 2 follow-on questions: 1. Does the IIRC show up anywhere on the GS3 engineering screens? It seems like this field is the only way to actually pin down the LTE cell ID, and I can't find it on my GS3. 2. Does the GS3 LTE Engineering Screen show LTE parameters even when the LTE signal is so weak that the phone is locked to CDMA? When I looked at the screen while in my house, it was showing an RSRP of -119, I believe from a transmitter about 3 miles south of me, which I know has LTE, while CDMA Field Test app was showing CDMA and Evdo RSSI's in the 90's, I think from a tower about 1.5 miles northeast which doesn't have LTE yet. (LTE is so close that it's like Chinese water torture! Drip . . . Drip . . . Drip . . . ) Again, thank you for your reply.
  13. tommym65
    Which leads me to an LTE question: I know that the engineering screens, the CDMA Field Test app, Netmonitor, etc., get and report the sector ID, and that it is the 1X ID, and they also get and report the BSLAT and BSLON, thus pinpointing the sector logical location (and the tower physical location in some places, including northern Illinois). LTE must generate some sort of ID field, in order for the phone to know what antenna it is connected to. Is there any way to find that LTE identification (if it exists), so that you can determine what different LTE antennas are seen by the phone, even if you can't directly see their locations? At least you'd know if you were seeing the same antennas, different antennas, new ones, etc., etc.

    Or maybe we are all just tiny flakes in a giant snow globe . . .
  16. tommym65
    Some work has been completed at 75% of Chicagoland NV sites, but fewer than 50% are complete, and fewer than that have LTE at this moment.

    "Cat-6" is a form of copper twisted pair. It is useful only for local area network segments. It can support very fast Ethernet (up to 1 Gbit), but it has virtually no relevance to mobile telephony. Regardless of what "somebody says", Ethernet on modern fiber, microwave, coax, and even satellite media can move enormous amounts of data very, very quickly and for very long distances. Essentially all modern public communication (read: "The Internet") uses the various IEEE Ethernet protocols in transmitting and receiving its data.
  18. tommym65
    Maybe we need some clarification here: "Ethernet" is the data protocol which provides packetization and error checking for whatever data you may want to transmit: Ethernet can transmit voice, video, html, or any other type of data. Ethernet can be carried on virtually any type of physical medium, including copper, coax, fiber, and microwave. The type of physical medium may determine the maximum and sustainable speeds of transmission, but does not determine the format or content of the data. Older cellular technology tended to use specialized, proprietary data protocols, primarily because Ethernet imposes a fairly large amount of overhead for error checking, addressing, etc., and the older physical media (e.g., T1) were so slow that using the Ethernet protocol caused unacceptable delays or loss of data. However, the newer physical media are fast enough to easily pass large amounts of data (including high quality standard voice and, in the future, VoLTE) using Ethernet. Thus, worrying that "Ethernet" backhaul will be too slow for "4G" communication is like worrying that leather seats will affect your car's brakes: It's comparing apples and boomerangs.

    Additionally, although 75% of Chicagoland sites have had some NV work done, far fewer than 50% are NV-complete. Thus, a given site may have 4G LTE or 3G improvements or 800 voice, but may be waiting for additional improvements., [Robert: What the heck are you doing posting replies at 2:45 in the morning? You, young man, should be asleep! ]

    Better to take a byte out of AT&T and Verizon.

    At Lake in the Hills Airport this morning: I had 3 consecutive tests over 30 Mbps, so the download speed is not a fluke. I could see the tower from my car window. LTE is slowly creeping to the Far Northwest Suburbs!
  22. tommym65
    No. LTE solves ALL of life's problems. That is why we are all addicted to this forum.
  23. tommym65
    It works, but seems to have very limited resolution. You are better off loading Google Maps into Safari, then having it place its icon on your iPad desktop.

    I can't stop myself. I just can't stop myself! . . . Ebenezer: You, boy!! You, in the street!! Boy: Who, me, mister? Ebenezer: Yes, you!! (A remarkable boy! A delightful boy!) Boy: What 'cher want, mister? Ebenezer: Do you know the poulterers over in Irma Street? Boy: I do! Ebenezer: The one with the fat crow hanging in the front window? Well, tuppence for you if you run over and have them deliver that crow to the Bob Herron Family on Sprint Lane! And double that if you do it in less than 5 minutes! (There, that should take care of Bob and Tiny AJ and all the Herrons!) Sorry, I just couldn't resist, in the spirit of the season and all that. And you, Robert, are a true and honest gentleman. You cannot imagine how much S4GRU folks appreciate your effort and attention to detail. (Irma? Why that's just up County Road J from Gleason. EVERYBODY knows that!)

    Become an S4GRU Sponsor and you will be able to see the exact locations of Sprint towers in McHenry County, and their exact current status. (A hint to the non-sponsors: There are many Sprint towers out here in far suburbia, but the number with operating LTE is somewhat low.) Also, the Sensorly.com Sprint 4G map is a very good indicator of where 4G is all over Chicagoland, because lots of people seem to be doing the mapping. Verizon has better 4G here, but AT&T coverage currently appears to be no better than Sprint, and may not be as good. Also, current Clearwire antennas show up on Clear.com's coverage maps, if you drill down to the right map resolutions. They are often not co-located with Sprint antennas.
