Normally the jammer is a device to control the signals from the base station. The main aim of this paper is to implement the mobile jammer in Smart Phones through an application that is not necessary to carry a device separately. This will be useful in the areas like School, Universities, Colleges, Library, Prisons and Hospitals to provide the peaceful environment and fraudulent. Only authorized persons can use it. The Functional unit of the setup contains the frequency producing unit, which produce a Noise frequency and blocks the connection between the mobiles and the base station. These can be done with the help of receiving signal capability of mobile phones. Keywords: Mobile jammer, Base station, Blocking signals. [1] INTRODUCTION Mobile jammer is a device that blocks transmission of signals between a mobile and the base station. That is the jammer creates a strong interference to block the signals. And this paper is about the mobile jammer to create a strong interference noise signal that same noise signal which may also be created by the mobile phone via the RF amplifier in the mobile phone. The mobile jammer device broadcasts the signal of the same frequency to the GSM modem. The jamming is said to be successful when the mobile phone signals are disabled in a location if the mobile jammer is enabled. [1] A jamming device transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cellphone base station in the tower. It is Called Denial of Service attack. TYPES OF MOBILE JAMMERS There are different types of mobile Jammers which are given below Remote Controlled Mobile Jammer Adjustable Mobile Jammer School & Prison Mobile Jammer Explosion Proof Mobile Jammer D.Jemimah Sweetlin, R.Shekin Sampath, G.Saravanan 1

Transformer: The transformer is used to transform the 220V AC to the other voltage levels (step up and step down) c. Rectification: The rectification is used to convert the AC voltage to the DC voltage and this process can be done in two methods which are full wave & half wave rectification d. IF Section: The IF section is just a triangular or saw tooth wave generator with the help of Voltage controlled oscillator. [Figure-4] shows the IF Section. [Figure-4] IF Section e. RF Section: The RF section is the heart of the mobile jammer because the output of the RF section is interacting with the mobile. [Figure-5] shows the RF Section.

4 [2] RELATED LITERATURE Azzam et al,[2] have presented two alternative methods for mobile Jammer implementation. Selective Frequency Jamming and Smart Jammer Design. They provide a solution for the problems of durability and cost relatedness. This paper describes Smart Jammer Design that achieves lower power consumption. Vishal et al, [3] have proposed mobile jammer on automobiles. This detect all nearly signals of incoming or outgoing call. It prevents driver mobile phone from receiving signals from base stations. This is done with the help of call handling operations. Sadixya Pradhan et al,[4] made the mobile jammer with a bug system that can receive the Rf section signals even in the silent mode and can detect both the incoming and the outgoing calls and also it can detect the text messages and videos. This gives a beep sound till the transmission gets completed. This is mostly used in the detective world. Sharad et al, [5] have developed a new idea that mobile jammer is done on android application which acts as a transmitter. They have invented an RX and TX application. In the mobile phone that has the TX, this acts as jamming unit and the user has the Rx file that automatically blocks the signals, when they are in range of TX unit. Nareshet al, [6] have done a mobile jamming signal for GSM and CDMA and it blocks for a certain period of time with the help of mobile jammer and ARM7. The time is controlled with the help of microcontroller and real tie clock chip (DS1307). Olumide et al, [7] has developed a jammer device which controls the cell carries in Nigeria. The range of the jammer is around 50 meters on AC and around 30 meters on DC. They conclude that the distance between Jammer and Base station increases, automatically effect of jamming distance will increased. [3] PROPOSED WORK The idea of implementing a technique of mobile jammer in mobile phone through application creates an impact that the mobile phone should contain the device of producing noise frequency. In jammer the RF section takes the role and that is the main heart of it. In mobile that noise frequency should be produced by itself. It is the main problem we face and in other way if the mobile produces a noise frequency the mobile which is producing a noise frequency may have many chances to lose their network connections etc These two are the major problems that we face while implementing this idea. The creation of application can be done and the main task is to produce the noise frequency to disturb the frequency which the mobile phone receives from the base station as same as the jammer produces. The next problem that comes is the noise frequency which mobile phone produces must be equal to the frequency range of 450MHz.The frequency of this range can only block or create a frequency and act as a noise between the base station and the mobiles to cut off the signals, Bluetooth, Wi-Fi, etc These are the major problems that we need to overcome while implementing a mobile jammer in a mobile phones through application.

This already is in market in different format. They have separate device. It is very expensive. No one knows how to operate this device. This application is very useful to government enforcement. It is very secure so only authorized people must use it. It is not expensive. If government happens to face many problems like protest and assassination, it can take one solution to stop this by cutting the network as a whole; people will be affected by this. Jammer when used separately is big and they carry many things. But when application is built in phone, it is easy to carry anywhere. They handle it very easily. [5] 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 calm and peaceful atmosphere in Hospitals Church/Mosques/Cathedral/Temple/Religious establishment. [6] MOBILE JAMMER IN MOBILE PHONES Mobile has the antenna to receive the signals and to send the signal. Then it has the RF section also and by this we can implement a mobile jammer. The circuit diagram given below can be helpful to understand the mechanism. This circuit diagram is the one in a normal phone circuit. This is enough to implement a mobile jammer in a mobile phone. [7] CONCLUSION This paper describes the mobile jamming techniques. With the help of the jammer any particular multimedia application can be disabled. An idea of implementing Mobile Jammer in Smart phones. We can use the jamming device through the Smart phones and controls the signals via Mobiles.
