Blocking the mobile phones signals with the help of jammer
Mobile jammer is used to prevent mobile phones from receiving or transmitting signals from the base stations. Mobile jammers can be used in practically any location, but are used in place where a phone call would be particularly disruptive like Temples, Libraries, Hospitals, etc. As with other radio jamming, mobile jammers blocks 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 phone unusable. Upon activating mobile jammers, all mobile phones will indicate “NO NETWORK” or there will no actual two-way communication. Incoming calls are blocked as if the mobile jammer is on, when the mobile jammer turned off, all mobile phones will automatically re-establish communications and provide full service.
