Today’s report in the Sunday Times that jamming equipment is being installed to prevent drones flying over sensitive sites should come as no surprise. My understanding is that at least one Premiership football club have been using jamming technology for some time to prevent drones flying over their ground.
It does raise some interesting questions. Outside of the security services jamming of radio signals, such jamming is illegal under the Wireless Telegraphy Act 2006, so there is the issue of ensuring that any blocking of signals is being carried out legally. The scope of the blocking is a further matter of concern. There is it seems the strong likelihood that radio signals will be affected outside of the immediate zone of protection. Whilst the jamming technology may be set to block signals on the commonly used frequencies for drone flying, what of drones being flown outside of those frequencies?
A further question is if jamming technology is blocking the signal to a drone, what will happen to the drone? Will it just fall to the ground, potentially causing injury? So who would be liable?
