1. Start the GPS device
2. Start the application, select the GPS device (only at the first run)
3. the program works automatically, records each cell you are passing by
3. export the records in a text file using the 'Export' command,
MCC, MNC, Cell ID, Latitude, Longitude, signal strength, LAC,
name of cell are saved in a tabulator delimited text file.
crossed: GPS is not connected
rotating: GPS connected, but position is not accurate yet
rotating slowly: valid position from GPS device.
Displays position in WSG 84 format, the name (if defined) or the ID of the currenct network cell with the signal strength in dBm, the current speed and the number of cells recorded in database.
Animation: estimates and visualizes the neighbourhood of the current position using the distances between the center of the passed cells, from tree (large distances) to skyscrapers (small distances).
Bar: visualize the efficiency for collecting (for the last 20 cells):
- dark grey: new cells in database;
- light grey: modified cells;
- no fill: unmodified cells.
You can import a previously exported file into the database. Only detected database files will be displayer. You will be offered to clear the existing database first, otherwise database will be merged with the imported content.
UPLOAD TO SERVER
Initiates a connection to our server storing thousands of the positions of network cells, and sends the modified records since the last upload to us. Server sends back the number of new and modified cells in database on server. Please help us to maintain and enhance our database. This database is available for registered users (upon request).
HOW DOES IT WORK
The application continuously monitors changes in cell ID and signal strength, and stores the 2 farthest positions with the highest signal strength for each cell. When exported, these positions are averaged to make the centre of the cell.
