How
does a Mobile Jammer work?
A
cell phone jammer is an instrument used to prevent cellular phones
from receiving and transmitting mobile signals to a base station.
The jammer effectively disables cellular phones in the area.
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 phones unusable.
A
mobile phone signal jammer is used to stop cell phone use in the
building. The jammer also stops Internet use through Wi-Fi
network and even blocks Bluetooth
connections. The cell phone signal jammer also puts an end to text
messaging, so students cannot SMS
each other, while the teacher is trying to teach.
The range of a personal cell phone jammer can be from 10 meters to
100 meters. The jammer can also work at a distance or behind
walls. Portable cell phone jammers are small and pocket-sized, and
look like cell phones themselves. The jammer fits into a pack of
cigarettes, so it is easy to hide. The jammer works well, even
when it is in an enclosure. Larger cell phone jammers are more
powerful and have a range that can be measured in miles.
A cell phone jammer has three antennas, one each for GSM, 3G and
DCS. The jammer works by broadcasting a white noise signal or a
wave bubble. First, you have to charge the jammer for at least an
hour. Then, you have to plug in the jammer, and turn it on, so
cell phones in the proximity will have no service available and
all calls are lost. Some cell phones switch to searching, which
means their signal is knocked out. When you turn off the jammer,
the signals normalize.
