  INTRODUCTION • A MobileJammer Circuit or a Cell Phone Jammer Circuit is an instrument or device that can prevent the reception of signals by mobile phones. Basically, a mobile jammer circuit is an RF transmitter which broadcasts radio signals in the same frequency range of GSM Communication.

  How Mobile JammerWorks? • A Jamming device transmits - same radio frequency of greater power as the cell phone ,disrupting the communication between the phone and the cell phone between the cell-phone base station in the tower. It is called a denial-of-service attack. • For any jammer circuit there are three main important circuit. When they are combined together, the output of the circuit will work as a jammer. The three circuits are : • 1 RF Amplifier • 2 Voltage control oscillator • 3 Tuning circuit

  •This causes interferencewith 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 frequency or tower to phone frequencies.

  Advantages Of MobileJammers • By using the cell phone jammers we can maintain law and order for maintaining peace. • It is very necessary to use cell phone jammers in nasal feared places. This helps the authorities to work their duty softly. • By using the cell phone jammers in the vehicles we can overcome accidents problem which is very helpful to the people. • We can provide security to VIP’s from the anti-social elements.
• 9.
  Disadvantages Of CellPhone Jammers • Cost oriented. • Requires special hardware. • People feel inconvenience. • VIP’s may lose some important calls.
• 10.
  Conclusion • Every technologyhas 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 restrict the communication network between the anti-social elements by using the mobile jammers. Cell phone jammers prevent the students from carrying cell phones to schools/colleges.
