Abstract:
GSM (Global system for mobile communication) is a communication system in which different frequencies operates for communication. It operates at GSM 900MHz & GSM 1800MHz frequency band. In Pakistan PTA (Pakistan Telecommunication Authority) controls different companies for GSM Band. In our project we have designed to block these communications during prescheduled time duration. We are going to make more efficient jamming device that disable communication of GSM from 5m to 7m. And this device automatically ON and OFF after match the time.
