G-NetTrack - fieldtest/netmonitor application for UMTS/GSM/LTE/CDMA/EVDO network

Hello,

Can somebody test this fieldtest/netmonitor android app on LTE and tell how it works.

 

Here is the link to Google Play:

G-NetTrack

 

Short description and screenshots:

This is a fieldtest/netmonitor application for UMTS/GSM/LTE/CDMA/EVDO network.

The application monitors the serving CELLID, LEVEL, QUAL, MCC, MNC, LAC, technology, cell serving time and neighbor cells CELLID/PSC and LEVEL.

Using the EVO LTE, I circumnavigated a local LTE site. Here is a screen cap of my results:

For comparison purposes, here is a screen cap of one sector on the LTE engineering screen:

A few conclusions...

 

We may have found an app that displays physical cell ID on all handsets. Note the integer values 129, 130, 131. They do not differ by the typical 169 interval, but that could be market dependent. This is also the first Android app I have seen that ostensibly identifies LACs, which are the GSM/W-CDMA/LTE equivalent of CDMA1X NIDs. The interesting thing about LAC 43 above is that it shares the same number with CDMA1X NID 43 in this area. So, I surmise that Sprint is numbering and shaping its LTE LACs to match its CDMA1X NIDs in many/all cases.

 

Now, boomerbubba really needs to take a look at these findings...

First of all thank you for your cooperation.

I updated the app. Try the new apk here.

CQI is "-" since it is not reported. I am trying to get MCC and MNC correctly (310 120). Tell me if it works now.

LTE Cellid is not PCI since it is 8bits reported (0-255) and not 0-503.

It is very likely that planners chose NID=LAC.

"Device is not compatible" I think. I already returned it to Verizon.

 

I have not seen this. The app uses GoogleMaps API, so if is not available it won't install but then the message is "Application not installed". Maybe it does not meet some of the requirements in the "Permissions" tab in app description in Google Play.

Note2 here. I noticed when on EVDO it shows the NID as the LAC. Haven't been able to check it out on LTE yet and see if it shows the LTE sector IDs. That would be cool if it does.

eHRPD shows as 4G instead of 3G and also my eHRPD RSSI is reporting the Sector ID as signal strength. Note2

Pretty neat app, though. Would love to see channel, too.

I really like the map tracking feature. Worked great on my Sprint Note 2. But didn't track on my T-Mobile Nexus 4.

When I look at the LTE engineering screen, the serving cell does not change, and I have been sitting at my desk for the test, yet the log shows it is connecting to different cells. As often as the log shows it changes, should I have seen the service cell change?

I have seen it change when I move from the west side of the tower to the east side.

With the update it does not log down any info while connected to ehrpd on the main screen. I dont know if it any different for cdma or lte

 

Same for lte, see that cqi is fixed. I have a hard time reading the dark blue rsrp (which is labeled incorrectly see below.) on the black background, probably the same for the dark gray. See 1st post screen shot. Also noticed what use to be rsrp in previous version is now rssi.

 

reread post, please don't take anything wrong , just relaying what I see. Love the app!

I found the error and fixed it. Here is updated v4.7 version on Google Play.

Thanks for your feedback. We have GSM/UMTS network and is not possible to test for CDMA phones.

 

Yes, looks like those issues are fixed, and the color is now just white for values. Just one question? I don't see the cell phone towers when looking at the map with cell selected. Should it be displaying them for Sprint?

 

Thanks for the app!!!

    • Sounds like an awesome project—keep us posted on how it’s going! Also—if you’re able to figure out logging, I can work with you to get the data uploaded to SignalCheck. 
    • Yesterday, I saw a post on Facebook from an old friend about the Evolve III Maestro, a $60 laptop (at Micro Center) that apparently has an LTE modem in it.  Specifically, the Quectel EC25-AF*.  The nearest Micro Center was sold out of new ones, but offered open box at $48.  So for $51 after tax, I walked out this morning with one.  An absolute steal. I backed up the Windows product key and then put Kubuntu 22.04 on it.  I spent a lot of time today trying to get the build tools installed so I could get the wifi module installed and running, and once I did that, I pretty quickly got to sending it modem commands, which I've never done before.  I don't have a SIM in it yet, but it does seem to function as it should.  (I figured out the command to get Timing Advance values out of it, but without a SIM, I doubt it would have such values.) Now I'm trying to puzzle out how to write some kind of script or small program to use it for logging purposes.  I think I've worked out how to send commands to it from bash using socat, but I need to pick specific commands to run.  I'd actually like to replace some of my phones with this if I can get it to record cells, with GPS, and cycle through a set of bands repeatedly.  My current phone collection consists of 9 phones other than my main S21FE, and they require babysitting while I'm logging.  It'd be nice to pare that down to a more reasonable number and let the computer do the work, hopefully in the back seat with less babysitting. - Trip ===== * Per the spec sheet, it supports B2/4/5/12/13/14/66/71.  That'd cover all of Verizon and US Cellular LTE, all but B29/30 on AT&T, and all but B41 and Sprint Keep on B26 for T-Mobile. 
    • More bizarre.  I just updated my other Ace without issue. - Trip  
    • Looking over the data so far, bidders can go back and reopen bidding on licenses that appeared settled. In the list below, not all counties are listed and only states with excess demand.  Typically 3 licenses per county for rural areas and some urban areas. Here is how many licenses per state had demand greater than supply: State count AK 3 AL 14 AR 3 AS 6 AZ 9 CA 12 CO 76 DE 6 FL 10 GA 66 GU 3 HI 3 IA 99 ID 47 IL 39 IN 43 KS 231 KY 23 LA 14 MA 5 MD 16 ME 1 MI 86 MN 9 MO 79 MP 12 MS 73 MT 69 NC 26 ND 109 NE 18 NH 13 NJ 6 NM 51 NV 24 NY 13 OH 29 OK 9 OR 30 PA 24 PR 25 SC 20 SD 83 TN 76 TX 236 UT 49 VA 22 VT 5 WA 65 WI 59 WV 26 WY 29
    • Looks like Dish has already taken back the 5x5 of n71 they leased to T-Mobile, and instead of narrowing NR here T-Mobile has gone for broke and made 600 NR-only. They can afford to do that here thanks to B12, and don't need to do that west of here because they weren't leasing 600 from Dish. Does mean that Dish is 10x10 for n71 here (which explains the 30ish Mbps upload peak I saw yesterday). Darned speculators hogging the remainder of the band So T-Mobile is running 140 + 15x15 MHz sub-6 NR here. AT&T is 40 + 15-45x15-45 (15x15 n5, occasional 15x15 DSS on n2 and/or n66 though I haven't seen both in the same area). VZW is 60 + 15x15, with the latter being n2 DSS. Wonder how soon VZW will try n48.
