    The likely 1x800 site, based on two 1x800 and one 3g offset sectors is in West Michigan market south of Grayling, MI on I 75 near Little Mud Lake For more details (premier): http://s4gru.com/index.php?/topic/5107-lte-800-band-26-sites-accepted-discussion/page-172#entry511229 plus a few above that.

    It should likely say Sprint? B4 if it not band 25, 26, or 41. plmn also dorked. Keeps you on your toes

    Tengen31 found the first b26 3x3 (in Two Harbors, MN), so I am certain he will sent diagnostics.

    The Nokia Mini Macros are smaller than the Airspan Air Harmony 1000 and 4000s. The Mini Macros are believed to be fiber fed and do have CA. We have only seen the Air Harmonies using Band 41 for backhaul and transmitting on another B41 single carrier. Sent from my LG-LS997 using Tapatalk

    The geographic box for the twin cities would be lie between 45.4 and 44.6 latitude and -92.8 and -93.6 longitude. Theses boxes do not need to be that exact. If 02A was found inside this box it would be Clearwire, elsewhere it would be Sprint. I would just use this for Boost, likely Virgin, and other Sprint MVNOs such as freedompop. There may be better solutions. You could allow these users to define what GCI markets are Clearwire like LTE Discovery, as it is unlikely that most users would transverse the county. The very few places with both would just have to settle for LTE where the GCI sector or earfcn could not distinguish the band. There are always some inaccuracies. So it can be done much better than today. Where this should rank in terms of priorities is a totally different issue. We are always constrained by limited time and resources. Other to-do items likely have greater benefit.

    I can think of other options http://s4gru.com/index.php?/topic/3060-signalcheck-android-app-to-monitor-your-2g3g4g-lte-signal-strengths/page-209#entry510970 You could also convert the plmn to Sprint's or pretend you do not have it. A setting might be needed for other Sprint Networks. Note that this is an even market Clearwire GCI as well.

    You see the same type of plmn flattening with freedompop in former nTelos areas, which is reported as Sprint which then conflicts with NE Sprint GCI. Likely need to put these special GCI areas with different base plmns in geographic boxes to be converted back to typical plmn. Of course what is the real plmn? Neither Boost or Freedompop maintain the network so they likely don't care / used for billing purposes. Then you have the issue that for regular Sprint users as mismatched plmn is a sign of questionable data, so converting the plmn for them is likely a bad choice. Sent from my LG-LS980 using Tapatalk

    Here is a screenshot showing some of the key changes for Sprint customers (highlighted): 1) LTE will now display the correct band. There is a lot more Band 41 out there than people thought. 2) MM is for Mini Macro, which has allowed Sprint to greatly expand Band 41 coverage due to far lower costs 3) On most Android 7.x devices you can see the earfcn and frequency midpoint without being rooted (some Samsung devices are not compliant). 4) On Android 7.x phones you can also see the earfcn for neighbors, which can sometimes help to find small cells. Airspan Air Harmony smalls are also indentified (SC) along with Magic Boxes (MB) and Triband Antennas (TB). Sent from my LG-LS997 using Tapatalk

    ingenium confirms status bar icon fix: https://lh3.googleusercontent.com/-1juLNX8kHmc/WVTa5SitVQI/AAAAAAABZeg/tS8HBeBEtwsYY1AgZE8lnsj_-n8KTKt4wCL0BGAYYCw/h2048/166603684631723242%253Faccount_id%253D1

    No issue with RSRP = 0 seen in either my or UPdownLoAD's logs from today. Logs were cleared or deleted.

    Android 5.0 logs had no unexplainable differences between before and after SCP RC1. Have two phones testing for whether RSRP = 0 in logs was a fluke or a real issue. Hope to report tonight.

    Received another GSM log. GPS is present. One erroneous entry for Verizon. 140 entries include these carriers: AT&T, T-Mobile, Movistar, entel, Starhub, Smart. Looks good as far as I can tell.
  15. dkyeager
    Ran through another 70000 records before and after release candidate 1 (RC1), also android 7.x. No issues. GSM data looks good from what I can tell. Gives you everything since the beginning of the log file. Correctly identified overseas carriers. Latest records were missing GPS data, so more data is being gathered for 1 day since we only had a very small sample. A couple of new LTE records in a very small small sample came back 0 RSRP, so running more data to check them out using a clean database. Will run a comparison of Android 5,x data before and after in the morning. Log generation appears faster.

    Only rarely do you see other carriers in the same band. Band 41 for example only then sees a carrier one or two away from current, thus if you are on 3rd carrier you don't see small cells or magic boxes immediately. If you stay in one spot for a while, for example a restaurant, it will find it in 15 minutes or so and then stay with the small cell. Same is true with multiple carriers in band 25. It prefers to stay with the one you are on even when driving by another b25 carrier that is stronger. You can use this to your advantage when hunting. Sent from my LG-LS997 using Tapatalk

    I have compared imex99 logs before and immediately after this release candidate update. No unexplained differences with about 90,000 records total. GSM file was empty, which is logical. I checked band display across all Sprint bands, they look fine. The one error that I got, that Mike could not and no one else replicated, with having 1x and LTE signal levels in the status bar still exists. I recommend that it be put in a possible bug list so this update can get out the door.

    I can confirm that zero is a valid PCI. We have it at a number of sites and bands on Sprint. Sent from my LG-LS997 using Tapatalk

    Sprint has changed Wi-Fi Calling to be compatible with Calling Plus (limited VoLTE) so you don't drop calls leaving Wi-Fi. It appears to need Andoid 7.x hence it likely broke the oldest Wi-Fi Calling as seen with the LG G4 which is on Android 6.x. Now uses AMR-WB codec (adaptive multi-rate - wideband) for HD Voice. Thus these phones we are finding can use Calling Plus, they just can not originate Calling Plus while on LTE like the two announced devices. How is the VoLTE limited? Lack of total priority over regular data along the data path is a key missing item, known as quality of service or QoS. The packet classification could be missing on the phones or all the equipment along the route does not know how to handle the type of service flag. Likely the phones lack packet classification since ToS has been around for 15 years or so. A person with one of the two select phones with full Calling Plus can answer this by testing voice calls while doing a data intensive task like watching an action movie with constantly changing scenes or doing speed tests.

    The LG G5 Wi-Fi Calling worked, but turning off Wi-Fi killed the call. On latest firmware, which is one month behind the LG V20 in terms of security patches.

    I looked up the US frequencies for that area. Always possible there are conflicts with Mexico. Here are the uncontested frequencies. Note that one lease may go away in a year. Sprint Call ID start finish bandwidth expires earfcn WQL202, B486 2496 2502 6 39680 WND375-L000001878 2518.5 2535 16.5 6/25/18 39957~ WND375-L000001878 2578 2584 6 6/25/18 40500 WQL202, B486 2618 2624 6 40900 Sprint would be clear in the immediate area into Imperial County CA. Here is the unabridged version: https://docs.google.com/spreadsheets/d/12La02ReEXzlVbz760c0H0XWOQB4Xt2HrM202-_WzO5c/edit?usp=sharing It is quite possible that they have another 5mhz, which could then use uncontiguous CA soontm when it becomes available with the latest phones at that time. If this B41 is from a small cell that other carrier could be the GCI sector 01, else 01 could be another sector from the site as well as 00 or 03.

    LG G4 Wi-Fi calling no longer appears to work. It did a few months ago. Thus not testable by me. This phone is one off the last firmware and not Android 7 (promised, but not in a fully tested state, by the end of the year by LG - who knows if it would make it to Sprint phones.) LG G4 Wi-Fi Calling still works, just very selective about which Wi-Fi it will use.
  25. dkyeager
    I suspect Airspan Air Harmony 1000 or 4000 either as a small cell or in groups of two or three at the site with simple b41 antennas. (edit: spotted photos of a site). If an Air Harmony was fiber fed, that could be the second carrier. If it is a split sector and that is a virtual GCI, what others do you get when you walk around the site?
