Signal Jamming
Signal jamming deliberately interferes with a wireless or radio signal to reduce or deny availability.
Mechanism
Interference raises the noise floor or otherwise prevents legitimate receivers from reliably decoding transmissions.
Indicators to watch
Sudden signal-to-noise degradation, retransmission spikes, channel-wide packet loss, and geographic/channel-specific interference.
Concept diagram
Defensive controls
Use spectrum monitoring, resilient channel planning, wired fallback paths, redundancy, physical controls, and incident response procedures.
Recommended security control
Wireless spectrum analyzer / WIDS
Only study RF interference in compliant, controlled environments.
