Technological advances have made possible the concept of remote communication, to be able to communicate with someone who may be a large distance away. Devices like wireless, radios, TVs, Telephones and satellite are, at their simplest, communication devices made for the transfer of information, be it text, audio or video, from sender to receiver over a large distance at great speed. While this has opened up a new world of opportunities to communicate with virtually anybody on the planet in a heartbeat, this also creates a curious dilemma for some government institutions like law enforcement and military. If these institutions do not want any criminals or opposition army to be able to communicate or create backdoors, the process to stopping the communication has become many folds difficult than it was in the pre-electronic era. This gives way to the field of electronics known as communication disruptors.
Communication disruptors are electronic devices used by military, government or law enforcement institutions to block any unwanted communication. The process is used heavily in warzones or during police actions to freeze out unwanted communication by the enemy/criminals. It is also utilized in sensitive government areas to ensure no unauthorized communication takes place.
The main principal of communication disruptors is based or frequency disrupting or radio jamming, blocking out specific frequency waves to travel through the area where the disruptors are installed stopping anybody to send or receive any transmissions.
Radio Waves Signal Jammer its Types, Techniques and Backdoors
Remote Communication of information has become an essential part of the lives of modern human beings and thus any attempts at disrupting this communication should be practiced with as much caution as possible. Civilian use of communication disruptors is a criminal offence in most countries and thus the main application of the technology is in the government sector organizations. However even the government’s use of blocking of communication can not or should not affect the lives and basic human rights of its people.
Jamming the communication is done through the use of a transmitter of the same frequency and modulation as the target receiving equipment. The transmitter, with enough power, can override signals and prevent them from reaching the receiver instead sending the more powerful signal of its own.
It is generally divided in to groups, Obvious and Subtle jamming.
Obvious jamming isn’t meant to hide the fact that the communication has been disrupted and thus can be heard on the receiving equipment. It usually transmits some sort of noise or music.
Subtle jamming on the other hand is used to secretly shut out the communication while giving the illusion that it is working correctly. Subtle jamming blocks out all the noise ensuring the people at the receiving won’t have any knowledge of the attempted message sent there way.
Digital wireless jamming of modern wireless signals like Bluetooth or WiFi is possible with very little power because of the lack of strength of the signals.
Scenarios of Application
The applications of frequency disruption are many and varied, and not all of these applications are legal and ethical. The legal application of the technology is with the government sector organizations like police, intelligence and army. The legal and ethical Jamming can be used in following different scenarios in these organizations.
- Battlefield and warzones
- Hostile situations in a civilian area
- Police raids on criminal hideouts
- Unauthorized communication in sensitive areas like military bases
- Cross border communication jamming
