As a Radiocommunications Specialist, I just thought that I would let you know of a very little known nasty practice that goes on in many of the worlds Hotels!
Have any of you ever wondered why your GSM Cell Phone suddenly fails to function whilst in the Hotel????
Well, a device called a Cell Phone jammer(Denier)may often be used, very illegal here, as Ofcom would have their nuts off if they found out, is used to jam the signals from the Cell Tower to the phone, forcing the user to make that all important call on the actual IDD Hotel Room telephone!!
Pretty lame huh!!
I know the company here that makes them, and ships them abroad for that use.
The only time they are used here in the UK, is to render phones inoperable in the prescence of VIP visits, as the Mobile Networks are used as trigger devices

So there you have it!!
The next time your Cell Phone fails to work in an overseas Hotel, when you know that you just got a signal outside it will now know the probable cause!
Sometimes when I notice it, I want to say something, but the poor Receptionist probably wouldn't have a clue what I'm saying, Lol

Any of our tecchie friends on the forum, pls feel free to comment.


The point of the thread is, everything in the world seems to be about money!
