just what to know GSM jammer applications
i know they can be use in
Hospitals ( but how)
Gas stations ( when mobile phone transmite electro-magnitic waves and jammer also do that then why jammer is batter then the mobile phone :roll:
The chances are a hostital ward is within a Faraday cage. It isn't specifically for GSM but any Electro-mag wave's that could interfere with sensetive equipment
I think what Styx is saying is that they use a Faraday cage. A faraday cage is just a metal enclosure. EM radiation can't penetrate metal more than a tiny thickness (with the exception of gamma rays and other super high energy EM). So if you enclose your area in a fine metal mesh EM can't go in or out. Its completely passive and generates no EM.
As an interesting side note: EM does penetrate metal a small distance. Photo diodes actually have a layer of aluminim on top as one of the contacts for the diode; the aluminum is so thin that light shines through it.
