MOBILE JAMMER
[attachment=57169]
Types of Jammers
Type A
-large number of oscillators
-interferes large amount of communication
spectrum
Type B
-”Intelligent Cellular Disabler Devices”
-detectors communicate with Base Station
-prevent the authorization of call establishment
Type C
-”Intelligent Beacon Disablers”
-compatible terminal is disabled
-eg. blue tooth technology
Type D
-jammer with a receiver
-jams the signal only when there is link between the base station and the mobile
-less electromagnetic pollution
Type E
-Faraday’s cage- blocks virtually all the EM waves
-EMI sheilding techniques
- EMI - Electro Magnetic Interface
-”quiet conference rooms”
Conclusions
High power and low power jammers
Variation in sizes
Easy to handle
