Determine Signal Strength of your Radios with SIGLOG
While this may not be an app for the common folk like myself, there are people like network engineers who may find this kind of applications useful. XDA member stephj has developed an app whose sole purpose is to log certain parameters coming from the radio devices in your phone. The app logs things like cell signal strength, GPS coordinates, Network ID, among others.
The app’s interface may not be as sleek as some of the latest Sense SDK type apps, but it does what it is supposed to do. It creates a log, which gets updated with the new parameters after the app polls the different radios. So, if you are interested in knowing about how good/bad signal you have, take a look at this app.
I wrote it a few months back whilst digging around in part of the RIL.
Written in Win32 C++ it’s lean, mean, rather basic, but it does the job. It requires a phone with GPS, as it calls the Microsoft intermediate GPS driver.
Once it is running, it checks the GPS and phone status every 5 seconds. If the signal strength has changed since the last reading, it writes a record out to \SIGLOG.TXT in the root directory of your device, in the format:-
Latitude,Longitude,Signal Strength,Mobile Country Code, Mobile Network Code,Location Area Code, CellID eg.
In this case the 090 is the signal strength, 0 to 100
