Intelligent FM signal jamming system

World is seeing a rapid growth in mobile communication and along with it is becoming difficult to maintain secrecy. There are device developments going on to mitigate this problem. The paper proposes a Mobile detection device which can be used as a metal detector to detect cell phones from the range of few centimeters to few feet's depending upon the Cell phones transmission strength and other parameters. Moreover there is high probability of secret leakages of defense meeting and big gangs use technological means to target high value item or for terrorist activities. This paper presents and proposes a mobile jammer that provides service denial for high security zones and is also used by the high profile person while travelling to avoid technological techniques of tracking.
