Future OpenCellID database content
* Add Cellid in long/short-format in measurements_.csv/cell_towers.csv
* Add value RNC (Radio Network Controller) in measurements_.csv/cell_towers.csv (UMTS)
* Add latitude and longitude from the calculated real position in the cell_towers.csv (Real place from the base station)
The actual position from the most cells is the middle from all measurements.
With the value signal maybe it is possible to calculate with the best signals (ASU = 31 or -51 dBm) the best calculated real place from the base station.
The value for the real latitude/longitude can used in example from a clf-import.
At the moment it is a mix with the middle and clf-import with the real position.
The real postion is useful for the apps G-Mon, G-NetTrack or RF Signal Tracker to create a cellfile or show alayer with the base stations.
Calculated middle from the cell:
changeable=1: the GPS position of the cell tower has been calculated from all available measurements
Real position from the cell:
changeable=0: the GPS position of the cell tower is precise; no measurements have been used to calculate it.
Example:
latitude_middle, longitude_middle, latitude_real, longitude_real
* Add the value cellrange.
With the value cellrange you can add the simple way for triangulation (see example google).
For this you use the calculated middle.
Lat=45.641502
Lon=8.812474
Range=1177 m
Example with the calculated middle and cellrange:
