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
