Just a question...
If you thought that someone in the near vicinity had a cellphone jammer about their person, how could you simply locate it?
This is in Europe - GSM. These items are illegal for civilian use in the UK, and I suspect that someone was using one on the train tonight
- for 30 minutes, no-one's cell phone worked in our carriage until we got to a station, then, like a miracle, they all started working again. If I moved to the next carriage (about 30mtrs, my phone started to work again - the signal got better the further I moved from my original carriage. All networks were effected (O2, Vodaphone, Orange), so I suspect that it was a jammer being used with a radius of about
15mtrs or so and when the person got off the train at the station, everything worked. We must have travelled through many cells and network providers in the 30 minutes, so it certainly wasn't network downtime...How could I identify who was using it? I hate the use of cell phones on trains - but this is more of academic interest...
Thanks
