Mobile jammer is used to prevent mobile phones from receiving or
transmitting signals with the base stations. Mobile jammers effectively
disable mobile phones within the defined regulated zones without causing any
interference to other communication means. Mobile jammers can be used in
practically any location, but are used in places where a phone call would be
particularly disruptive like Temples, Libraries, Hospitals, Cinema halls,
schools & colleges 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 jammers for government
switched over to sell these devices to private entities.
As with other radio jamming, mobile jammers 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 jammers , 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 jammer 's 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 organisation to very high power military jammers to jam a
