RF Jamming
- •
def
- •
intentionally transmitting interfering wireless signals to deny wireless communication, decreasing the signal-to-noise ratio at the receiving device
- •
- •
distinguish from
- •
unintentional interference (e.g., a microwave oven or fluorescent lights) — jamming specifically means someone deliberately wants your network to fail
- •
- •
types
- •
constant (random or legitimate frames), random timing, or reactive (only jamming when it detects someone else trying to communicate)
- •
- •
note
- •
needs to be physically close to be effective; locating a jammer requires directional antennas and an attenuator ("fox hunting")
