What Are Mobile Phone Network Signal Jammers? An Overview

Mobile phones are being misused at a very threatening level nowadays. Right from being a threat to someone’s security to being a weapon for cheating in exams, this technology is being used for some of the worst reasons in the world.

Thankfully technology has not only created phones, but Mobile Phone Network Signal Jammers as well!


What are Jammers?


Jammers are devices that disable any communication from mobile phone or GPS in its effective area. These jammers can be portable as well as stationary. The use of jammers has increased manifold in the last few years and they now find applicability in military, education departments, meetings, VIP security, as well as the corporate sectors.

How do Jammers work?

Mobile phones or any other communication devices work through transmission of radio waves. The nearby mobile tower receives the transmission and sends a signal to the receivers’ mobile, which in turn makes communication possible.

To prevent such communication, jammers transmit signals of the same frequency as the mobile phones and interfere with the mobile’s transmission to the cellular tower. This interference disables the mobile network thus barring it from communication of any sort.

What are the various uses of a Jammer?


The mobile phone network signal jammers are used for various purposes; some of them are listed below:

●    Military area - Highly sensitive areas like military cantonments install mobile phone jammers to disable any transmission for the purpose of security. These jammers prevent the military hub from spying activities as well.

●        Examination Halls - Easy entry of high-tech cheating devices like ultra small Bluetooth devices, pen cameras and mobile phones enable cheating during examinations. Portable mobile phone jammers block the communication of such devices with gadgets outside the examination centre, thus playing a successful role in enabling fair conduct of examinations.


●        Prison Mobile phone Jammers - Mobile phones can easily be smuggled inside the prison and act as a threat to the system’s security as inmates use them to re-establish harmful contacts with their allies. The stationary jammers installed in the prisons act as an excellent tool to prevent such incidents and maintain the sanctity of the system.



The usage of mobile phone signal jammers has increased a lot in the last few years. With the advancement of technology, usage of these jammers has become a necessity for all the reputed educational institutions as well as for high security areas. The mobile phone network signal jammers thus acts as a multi-purpose tool, whether it is needed in an examination hall or in the parliament house.

In this digital era, the term ‘Spectrum Warfare’ has replaced the term ‘Electronic Warfare (EW).’ Spectrum Warfare is a blend of electronic warfare technologies and electro-optical technology. It involves usage of devices like Powerful Signal Jammers for Military , interception, radars, electronic spoofing, infrared sensors, multi-spectral and hyper spectral sensors, visible-light sensors and laser technologies. An enormous amount of strength and accuracy has been infused by the usage of the afore-mentioned technical advancements, thus creating a much better detection system in the armed forces and a higher capacity to combat impending attacks. Currently the radar system is frequently being used to detect real-time enemy actions and to identify their location to help missile launches at the targeted locations. The radar jamming technology offers a perfect solution to warfare threats through emission of radio signals at a specific frequency, which in turn degrades the qu...
