The ways with human use to communicate with one another have changed a lot recently. The ways of communication have improved a lot over the years, and have made transition from hand written letters all the way to signal communication.

Wireless signal communication is one of the most advanced and seamless technologies in use these days.However, signal technology came with the invention of signal blockers as well.Signal jamming (bloqueador de celulares) can be easily done by blocking the signals of one device by colliding them with signals of same frequency and high power. When this happens, the receiver stops working properly because of the signal interruption.

History of Signal Jamming

Signal jamming was first widely used in the world wars and the Cold War to block signals of enemies. Jammers were used to block any type of communication between spies and their countries.

However, things started changing after the cold war. When the Soviets were defeated, the west made huge leaps in technology and research. Moreover, when signal jamming was not in much need, it was labeled illegal in many areas. The government, military, and other agencies still use signal jammers For certain applications.

Different Types of Signal Jamming

There are two different types of jamming, which are mechanical and electrical.

Mechanical jamming is older as compared to the second type. This type of jamming usually worked by using reflectors to send back the signals to its resource to confuse it.However, a problem with the devices was they were big, and easily detectable as well. So, this con of mechanical signal jammers defeated their purpose, which as privacy and security.

The second, and more modern type of signal jammers is electrical jammers. These devices are really small, and interrupt the signals by colliding them with signals of same frequency but higher power.
