DECLARATION OF ORIGINALITY

I understand that all my project work must be my own unaided work. If I make use of material from any other source I must clearly identify it as such in any interviews, report or examinations. I understand that my report must be written unaided in my own words, apart from any quoted material which I must identify in the correct manner. I understand that the work which I shall present for assessment must be work carried out by myself during the project period which has not been previously prepared. Where any such previous work is made use of in the project, I shall make this clear in any interview, report or examinations. I understand that violating of these conditions may result in a mark of zero for the component or component of assessed work affected. Names: Signatures: MUHAMMAD AZEEM AFZAL

ABSTRACT

This handy, pocket-size mobile transmission detector or sniffer can sense the presence of an activated mobile cell phone from a distance of one and-a-half meters. So it can be used to prevent use of mobile phones in examination halls, confidential rooms, etc. It is also useful for detecting the use of mobile phone for Spying and unauthorized video transmission. The circuit can detect the incoming and outgoing calls, SMS and video transmission even if the mobile phone is kept in the silent mode. The moment the Bug detects RF transmission signal from an activated mobile phone, it starts sounding a beep alarm and the LED blinks. The alarm continues until the signal transmission ceases. Assemble the circuit on bread board as compact as possible and enclose in a small box like junk mobile case. You may use a short telescopic type antenna. Use the miniature 9V battery of a remote control and a small buzzer to make the gadget pocket-size. The unit will give the warning indication if someone uses Mobile phone within a radius of 1.5 meters.

ACKNOWLEDGEMENT

My supervisor Mr. Nafees Ahmed have a significant role in my project. I am very thankful to him for his guidance and efforts. He was very understanding and cooperative throughout my degree. It is because of his precious time he devoted for me that I have achieved my goal.

I would like to thank my beloved father, who helped me and encouraged me to achieve my ambition. He gave me hope when I was hopeless. I would also thank to my mum. It is result of her prayers that today I have achieved my goal.

Thanks to BAHRIA UNIVERSITY for providing me opportunity for the research and the lab resources.
