IMPLEMENTATION OF
HIGHLY EFFECTIVE MOBILE
/ CELL PHONE JAMMER
MOBILE / CELL PHONE JAMMER Cell Phone Jammer is an instrument to prevent cellular phone from receiving and
transmitting the mobile signals to the base station.
Mobile Phone Jammer can block all kinds of mobile
phone's ringing sound at all places such as church,
mosque, library, Movie Theater and meeting room
The Cell Phone Jammers are a necessity for
accomplishing a more cultured society because there
is a growing demand for silence at places like hospital,
libraries and Movie Theatres
MOBILE JAMMERS – OPERATING PROCEDURE Jammers block cell phone use by sending out radio
waves along the same frequencies that cellular
phones use. This causes enough interference with
the communication of cell phones and the towers to
render the phones unusable.
On most retail phones, the network would simply
appear out of range. Most cell phones use different
bands to send and receive communications from
towers. Thus jammers can work by either disrupting
phone to tower frequencies or tower to phone
frequencies.
Small devices tend to use the former method, while
larger more expensive models may interfere directly
with the tower. The radius of cell phone jammers can
range from a dozen feet for pocket models to
kilometers for more dedicated units.
The power of the 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
CELL JAMMER - HISTORY
Cell phone jamming devices were
originally developed for law enforcement
and the military to interrupt
communications by criminals and
terrorists.
Some were also designed to foil the use of
certain remotely detonated explosives.
The civilian applications were apparent,
so over time many companies originally
contracted to design jammers for
government use switched over to sell
these devices to private entities.
Since then, there as been a slow but
steady increase in their purchase and use
especially in major metropolitan areas
CELL PHONE JAMMER – HOW IT WORKS
A phone jammer transmits low power radio signals to cut off communications between cell phones and cell base stations.
It does not interfere with any communications other than cellular phones within the defined regulated zone. Upon activating a phone jammer, all
idle phones will indicate "NO NETWORK."
Incoming calls are blocked as if the cellular hand phone were off. When the phone jammer is turned off, all cell hand phones will
automatically re-establish communications and provide full service
