UMTS/GSM/LTE/CDMA/EVDO Network Monitor and Drive Test tool

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

Download G-NetTrack Pro - full version here:
G-NetTrack Pro (Trial Version) on Google Play -
G-NetTrack Pro video demonstration:

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

LEVEL and QUAL depend on technology:
- 3G - RSCP and ECNO
- 4G - RSRP and RSRQ

Only for 4G also SNR and CQI are monitored.

The reported measurements depend on the phone and are not available on all mobiles. For example most phones do not report RXQUAL on GSM and only some report ECNO on 3G.

If LEVEL is -200dBm that means your device does not report correctly and you have to search for a software update from your device manufacturer.

***NEW*** G-NetDiag - online tool for visualization and postprocessing of text log files is available - check G-NetDiag section on

***NEW*** Phone measurement capabilities survey - go to Menu-More-Measurement Capabilities and see if your device reports correctly CELLID, LEVEL, QUALITY, NEIGHBORS. Share your results and see the results from the survey for different phone brands.

There are two modes in which app could be used - instant and log modes.

1. Instant mode - this is a quick mode for fast measurements
- start the app
- enable the mapview (Menu - Enable Map and GPS)
- select measurement (LEVEL, QUAL, CELLID, DL-bitrate, UL-bitrate, Speed)
- when you finish with measurements you can export the observed measurement to kml or take a screenshot.

2. Log mode - this is more sophisticated mode. You can also start optionally voice and data sequences (that's why you see in the app permissions "Services that cost you money - Directly call phone numbers") in order to monitor the network for blocked and dropped calls and to measure upload and download bitrate. Don't lock the phone while the log is running.
- start the app
- select what measurements you want to log (Menu-Settings)
- start log (Menu - Start Log)
- the app starts to create kml and text tab export for the selected measurements
- it also creates event kml and text file - for cell reselections, handovers, Call Start, Call End, Call Drop, Call Block
- when you are finished with measurements press End Log button
- you can find kml exports and tab exports in folder G-NetTrack_Logs on sdcard

Using application you can easily pinpoint network problems like:
- blocked calls
- dropped calls
- bad coverage - low RXLEVEL
- low uplink and downlink data throughput
- lack of dominant server causing lot of cell reselections and frequent service interruptions - when the serving cell time is small
- weak 3G coverage - when you have a lot of reselections between cells on 3G and 2G

- if you have information about the sites you can create cellfile and you can view sites on map - see the screenshots. Put the file in the folder G-NetTrack_Logs/cellfile. Go to G-NetTrack section on for instruction how to create file and sample file.
- option to load cellfile, show cellname labels and serving cell line is in Menu - Settings
- if you add too many cells to cellfile the performance of the app could be slowed on some mobiles when the Map tab is active

For log files new point is created when the distance difference is >15m or cellid has changed. The icon size varies with technology - size2G < size3G < size4G.

KML log file can be used with Google Earth or G-NetLook in order easily to view measurement results.
Text log file can be used with G-NetDiag, for statistical purposes or imported in MapInfo in order to create coverage maps.

If you use antivirus software allow the app to create folders and write on sdcard.

Hi man, you're doing a great job making G-Net Track work with Android.
I enjoyed using it with WM6.1 on an HTC Touch HD that unfortunately broke last year.
Is there any WP7 version in your current/future plans?

Updated to 3.5

New things:

Added automatic voice call sequence - the events CALL START, CALL BLOCK, CALL DROP and CALL END are included in events.kml and in events.txt file.
App should be in foreground in order sequence to run.
if it is in the background the sequence is paused.
How to set parameters:
- click [EDIT]
- change the values
- click [SAVE]
Note: In 3G during the voice call cell parameters are not updated. So in 3G use short calls.
In order not to be charged you can call number which is not answering

Updated to 3.6

Now you can measure the download bit rate.
Data sequence is added to program functionality - type target URL and start data sequence. New kml file for DL bitrate is created.
Choose bigger file in target URL in order to have bigger download speed.

Where do I find documentation on what all those values mean and value indication?

seems to work on my sprint touch pro 2 , just saying that it worked since there was a comment on how it didnt work on cdma

also the g-netspeed app gives a different speed than ookla's speed test app, wondering which is more accurate if anyone knows.

Ookla test is based on download and upload of file to their specified server (usually the closest server). G-netSpeed estimates the speed to locations that you choose, that's why you get different results.
I am trying to make G-nettrack to work with Cdma, but we don't have cdma here. So if somebody is willing to try cdma version just send me a message.
