Location Finder and GSM mapper

Before using this app, its recommended to read the user manual at http://friendscorner.info
This FREE app will find your location based on the GSM Network (NOT FOR CDMA PHONES) in terms of latitude and longitude. It does not require GPS. The location address is also displayed using geocoder. The app also gives information of the the serving cell and neighbouring cells information alongwith their signal strength. The state is updated automatically as one moves from one cell to another. The app is completely FREE OF ADS . The endeavor is to provide a free and user-friendly app , evolving with each passing day based on the positive feedback from users.
Location Finder gives the serving and neighbouring cell LAC and CID. The app uses google api to find network based location using the serving cell CID and LAC. The address obtained using the network location is also displayed.
Internet data connectivity is required for getting location coordinates and its corresponding address. It is advised to change to 2G from 3G as the required LAC and CID data may not be obtained when in 3G mode.
As you move the serving cell is selected by your phone based on the RSSI received of the GSM base station. The app would display the change in serving cell and associated change in coordinates and location as you move. The updation will take place as long as the phone is active and not in sleep mode. When the app is active it would not let the phone go in sleep mode. Its not possible to monitor the cell location and change in signal strength when the phone goes in sleep mode due to hardware and software limitations.
When you physically move with your cell phone along a route , the location of all the BTSs being operated by your service provider along that route are scanned and stored in a sqlite database. These are then shown on a googlemap to give you an idea of the GSM coverage in respect of your service provider.
