3 Introduction Cell phone jammers are devices that create a temporary "dead zone" to all cell phone traffic in their immediate proximity 3
4 How cell phone jammer works A jamming device transmits - same radio frequencies of greater power as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower. It's a called a denial-of-service attack. 4
5 This causes interference with communication of cell phones and towers to render the phones unusable. On most phones, the network would be out of range. So Jammers work by either disrupting phone to tower freq.. or tower to phone frequencies. 5
6 Jamming techniques Type "A" Device: JAMMERS Type B Device: INTELLIGENT CELLULAR DISABLERS Type C Device: INTELLIGENT BEACON DISABLERS Type D Device: DIRECT RECEIVE & TRANSMIT JAMMERS Type E Device: EMI SHIELD - PASSIVE JAMMING Amity university rajasthan 6
7 Jamming techniques 1. Type "A" Device: JAMMERS This type of device comes equipped with several independent oscillators transmitting jamming signals capable of blocking frequencies used by paging devices as well as those used by cellular systems control channels for call establishment. 7
8 Jamming techniques 2.Type B Device: INTELLIGENT CELLULAR DISABLERS Unlike jammers, Type B devices do not transmit an interfering signal on the control channels. The device, when located in a designated quite area, functions as a detector. It has a unique identification number for communicating with the cellular base station. 8
9 Jamming techniques 3. Type C Device (Intelligent Beacon Disablers) Unlike jammers, Type C devices do not transmit an interfering signal on the control channels. The device, when located in a designated quiet area, functions as a beacon and any compatible terminal is instructed to disable its ringer or disable its operation, while within the coverage area of beacon. 9
10 Jamming techniques 4. Type D Device (Direct Receive & Transmit Jammers) This jammer behaves like a small, independent and portable base station, which can directly interact intelligently or unintelligently with the operation of the local mobile phone. The jammer is predominantly in receive mode and will intelligently choose to interact and block the cell Phone directly if it is within close proximity of the jammer. 10
11 Jamming techniques 5. Type E Device (EMI Shield - Passive Jamming) This technique is using EMI suppression techniques to make a room into what is called Faraday cage. Although labor intensive to construct, the Faraday cage essentially Blocks or greatly attenuates, virtually all electromagnetic radiation from entering or leaving the cage - or in this case a target room.

20 Types of jammer device Types of cell phone jammer device There are many types of cell phone jammer device which is used in our daily life.as we take a example of class room,where we does not want to use of cell phone than there we can use cell phone jammer device.by this we can produce the interface between the cell phone base station and cell phone. resulting it disconnect the cell from base station.and we can not receive the any calls from base station. For this there are many types of cell phone jammer devices which is given as below: Contd.
21 Remote Control cell phone jammer Adjustable cell phone Jammer School &Prison Phone Jammer Explosion Proof cell phone jammer Police & Mila try Phone Jammer Portable Cell Phone Jammer

23 Application To maintain the complete silence in library and lecture hall To avoid fraud in examination hall To avoid disturbance in class room For providing security in business conference, board of directors rooms, seminars, etc., For providing calm and peaceful atmosphere in Hospitals Church/Mosques/Cathedral/Temple/Religious establishment 23
24 Future scope of Jamming Technology While the law clearly prohibits using a device to actively disrupt a cell-phone signal, there are no rules against passive cell-phone blocking. Companies are working on devices that control a cell phone but do not "jam the signal. 24
25 Conclusion Every technology has good aspect as well as bad aspect the important thing is,how we are using it. Cell phone jammers are very useful to the society from the anti-social elements. We can save our national leaders. we can restrict the communication network between the anti-social elements by using the cell phone jammers. Cell phone jammers prevent the students from carrying cell phones to the colleges. As every thing goes fine, it is very necessary to implement in all the colleges 25
