How Jammers work

Understanding how jammers work may seem like a technical challenge at first, but the reality is simpler than you might imagine. At a basic level, an inhibitor is essentially a radio transmitter. However, instead of sending useful information, it transmits a signal of "noise" or interference.

This "noise" is specifically designed to interfere with and block wireless signals in certain frequency bands. By doing so, the jammer prevents other devices, such as cell phones or radios, from receiving or transmitting information on those bands. Some jammers are capable of blocking multiple frequencies at the same time, while others are designed for more specific targets.


Main Jammer Components

Although there are different types of inhibitors with various specifications, most share certain key components:

  • Antenna: Captures and transmits the interference signal.
  • Oscillator: Generates the signal or "noise" that interrupts specific frequencies.
  • Battery: Power source for the device. Some models can be connected directly to the electrical current.
  • Control Circuit: Allows the user to adjust the frequencies to be blocked and to control other functions of the device.

It is crucial to mention that the effective range of an inhibitor will depend on its power and specific design. While some models can affect devices several meters away, others, especially those designed for personal use, have a more limited range.


Common Uses and Applications of a Jammer
