Reactive Jammer Systems

There is a fundamental difference between permanent and reactive jammers. Permanent jammers are always in transmission mode and interrupt any communication in one or several frequency ranges. Reactive jammers consist of a detector and a transmitter. Under normal circumstances the transmitter is deactivated, and the detector checks one or several frequencies. As soon as a communication is noticed in the defined frequency range, the control system actuates an alarm and activates the jammer that prevents the communication using a jamming signal. The advantages of a reactive jamming are a significant reduction of electricity consumption and lower radiation exposure.

The following signals can be jammed:

  • Amateur radio
  • Broadcasting News
  • Predecessor GSM
  • GSM (3G)
  • UMTS (4G)
  • LTE (5G) Mobiltelefon
  • GPS (US)
  • Galileo (Europe)
  • GLONASS (Russia)
  • Beidou (China)
  • QZSS-SAIF (Japan)
  • IRNSS / GAGAN (India)
  • Satellite Com
  • WLAN
  • Bluetooth
  • Radio remote controls, Hand-held transmitter
