RF Jamming

Radio Frequency or RF Jamming is one of the easiest methods of defeating a wireless system – the wireless equivalent of cutting the wires on a traditional wired system. The open medium nature of WiFi makes it vulnerable to various attacks, among them, attacks against availability is wifi jamming. WiFi jamming sends a lot of noise in the environment, making it impossible for other nodes to send messages through available channels.

Types of RF Jamming

AirGuard is capable of detecting four types of RF jamming:
  1. 1.
    Constant Jammer:
    Continually emits a radio signal that interferes with communication.
  2. 2.
    Deceptive Jammer:
    Constantly injects regular packets to the channel without following CSMA/CA procedure.
  3. 3.
    Random Jammer:
    Intermittently emits the jamming signal.
  4. 4.
    Reactive Jammer:
    Jam and simultaneously sense/discern/detect the legitimate transmission.

Detecting RF Jamming

AirGuard adopts unique technologies to detect all types of RF jamming while keeping a very low fail rate on the detection. That is, the system would not easily treat massive transmission of WiFi data as an RF Jamming attack. In contrast, the signal interference sent by a jammer can be efficiently detected in seconds.
