Cell Map

Cell MapHaving trouble getting a signal? Want to know where your local cell towers are?

Cell Map plots the location and strength of all the cell transmitters that your phone is connected to. Just move closer to one for a better signal!

Cell Map can even locate transmitters that are too weak to make a call from, ideal for areas with poor signals.

Currently only supports 2G connections but many 3G and 4G transmitters are often located on the same tower.

Hi, does my 4.0.4 android have to be set to 2G only for this app to work? Will you be upgrading the app for 3G and 4G?
How long should it take to aquire radio signal? On the signal level, what do the different colors indicate? Thanks, Ken

Hello,

In 3G mode it really depends on your device rather than the Android version, unfortunately some manufactures haven't fully implemented the system calls necessary for acquiring the cell locations.
The signal level colours range from red through through to green to indicate low to high respectively. As with the location the actual signal level reported varies between manufactures.
I intend to add 4G support at some point, I just need to get my hands on a 4G capable phone.

Can this app detect a stingray being used? Like a tower in motion, or a new tower that wasn't there before?

Surveillance instruments are designed to act as a bona fide device so cannot be detected by standard hardware. If these can be found it would require very specialist knowledge and hardware.

Love this app and use it on my phone a lot as I live in the outback of Wales where towers are rare.
Is there anyway I can run it on my Linux laptop with Zte dongle and three network to find which tower I am using. There are only 3 towers on the local tv relay masts in my area and all are slightly obstructed by hills.
can't put the sim in my phone as it's data only.
Thanks, Alan

Good to hear it's useful, unfortunately Linux doesn't provide the required access to the radio that Android does so I won't be able to write a Linux version.

What does this mean?
This app used to work on my galaxy s5, but doesn't now.
Now I get this message repeatedly and connected towers never show.
How can I get the app to function again?

Thanks

Thanks for the feedback, I hope to have a fix for this issue in the next few days.

Downloaded 1.4.2 - still doesn't work, which is too bad as this was really useful when it did work.

I've had some more feedback about the issues I hopefully I'll be able to fix them soon

Hello,

is it possible to integrate openstreetmap as map and the Mozilla Location Service as alternative?

Hi Jörg,

I hope to be able to add both at some point, not sure when though.

Hello,

your app is very good. Is it possible to include following features?

- Show the range/accuracy as a circle from the actually cellid
- Integrate Openstreetmap as a layer (Possible to choose between google and openstreetmap) i like too
- I like Mozilla Location Service too. Use the api from MLS or the downloaded data from https://location.services.mozilla.com/downloads for a Offline Geolocation as a internal database
- Import clf files (http://nobbi.com/monitor/filesen.html#cilalist.clf)
- If cellid is cached, go directly to this point (Not Lat/Lon 0,0) and use the latitude/longitude from cached cellids
- Add mcc, mnc, lac, cellid in the export file

Best regards.

Sebastian
