Thread: Question about cell phone security

It's more likely that they are worried about unshielded electronics then you being a spy. That's why you aren't allowed to use phones on planes. Electronics (specifically radios) that aren't properly shielded against microwaves can be disrupted if you use your phone.

So they could tell in that sense or would just see that someone used a cell phone?

I'm just trying to understand that part...I understand the security risks and why they don't want cell phones in those areas...but the electronic side of it confuses me..

if your phone's on, it's transmitting all the time
(it needs to be in almost constant contact with the nearest phone mast - this is so the phone network knows which mast to send your incoming calls to)

because it's transmitting all the time, they can monitor any phone use by monitoring the right frequencies
plus, if they're determined, they can triangulate your position to within a few metres

*edit*
btw, somewhat relevant
