Not cell GSM encryption. Encrypted data over 3G/Edge carried by GSM. Big difference.
And how to track the UAV with sectorised antennas?
To improve the cellular coverage the mobile base station antennas are given small tilt(around 2-3 degrees) towards the intended area (houses). Then also signals are not very great inside some of the rooms. I doubt this can be used to control the drones which operates at high altitudes and are very dangerous if gets out of control. In addition, I suppose these drones will be operating mostly in farmost places not in big cities, how it is possible to get a good mobile coverage there. You have to install a base station and microwave link for mobile everytime you go to new remote location. The most feasible and safe option is to use dedicated communications satellite. I suppose this is the only reason launch of new UAV is getting delayed.
ISRO is fabricating dedicated communications satellite for Indian Armed forces with the inputs from DRDO to provide all weather encrypted communication over the nation. It is easy to imagine that it would have the provision for remote controlling of drones and unmanned combat vehicles, must for precision strike and control.
The most simple option for pak is to use drones at a line of sight and keep the mobile tracking stations within the operating range. Once they sort out the satellite problem, it could be implemented later.
