SIGNAL JAMMER

In recent times, the utilization of electronic devices has significantly increased in communication and technology, but there has also been a rise in their misuse, particularly in restricted areas like examination halls and confidential rooms. One of the electronic devices commonly misused is mobile phones, which has become a prevalent issue in different sectors of society. To address this problem, a suggested system has been proposed that can effectively operate in areas where the cell phones are restricted. This system is designed to identify spying and unauthorized video transmissions, as well as incoming and outgoing calls and messages, even when the mobile phone is in silent mode. Also, to enhance security in private networks or block unwanted access to wireless networks. The system is composed of a small-sized detector-jammer circuit that utilizes CA3130EZ to detect RF transmission signals within the frequency ranges and then block the Wi-Fi signals.
