  • ABSTRACT

    Mobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base stations. Mobile jammer effectively disable mobile phones within the defined regulated zones without causing any interference to other communication means Mobile jammer can be used in practically any location, but are used in places where a phone call would be particularly disruptive like Temples, Libraries, Hospitals etc. As with other radio jamming, mobile jammer block mobile phone use by sending out radio waves along the same frequencies that mobile phones use. This causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable. Upon activating mobile jammer, all mobile phones will indicate "NO NETWORK. Incoming calls are blocked as if the mobile phone were off. When the Mobile jammers are turned off, all mobile phones will automatically re-establish communications and provide full service. Mobile jammers effect can vary widely based on factors such as proximity to towers, indoor and outdoor settings, presence of buildings and landscape, even temperature and humidity play a role.

    Chapter 1

    INTRODUCTION Communication jamming devices were first developed and used by military.

    Where tactical commanders use RF communications to exercise control of their forces, an enemy has interest in those communications. This interest comes from the fundamental area of denying the successful transport of the information from the sender to the receiver.

    Nowadays the mobile jammer devices are becoming civilian products rather than electronic warfare devices, since with the increasing number of the mobile phone users the need to disable mobile phones in specific places where the ringing of cell phone would be disruptive has increased. These places include worship places, university lecture rooms, libraries, concert halls, meeting rooms, and other places where silence is appreciated.

    Mobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base stations. Mobile jammer effectively disable mobile phones within the defined regulated zones without causing any interference to other communication means Mobile jammer can be used in practically any location, but are used in places where a phone call would be particularly disruptive like Temples, Libraries, Hospitals etc. Mobile jammers were originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosives. The civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise & reckless invasion of privacy. Over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities.

    As with other radio jamming, mobile jammer block mobile phone use by sending out radio waves along the same frequencies that mobile phones use. This causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable. Upon activating mobile jammer, all mobile phones will indicate "NO NETWORK. Incoming calls are blocked as if the mobile phone were off. When the Mobile jammers are turned off, all mobile phones will automatically re-establish communications and provide full service. Mobile jammers effect can vary widely based on factors such as proximity to towers, indoor and outdoor settings, presence of buildings and landscape, even temperature and humidity play a role.

    The choice of mobile jammers are based on the required range starting with the personal pocket mobile jammer that can be carried along with you to ensure undisrupted meeting with your client or a personal portable mobile jammer for your room or medium power mobile jammer or high power mobile jammer for your organization to very high power military jammers to jam a large campuses.
