Sequence diagram for a Wi‑Fi deauthentication attack. Unlike most radio jammers, deauthentication acts in a unique way. The IEEE 802.11 (Wi-Fi) protocol contains the provision for a deauthentication frame. Sending the frame from the access point to a station is called a "sanctioned technique to inform a rogue station that they have been ...
Radio jamming is the deliberate blocking of or interference with wireless communications. [1] [2] In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio. [3] The concept can be used in wireless data networks to disrupt information flow. [4]
Several online retailers and drone technology companies are marketing the sale of radio frequency jammers as drone deterrence or privacy tools. ... disable security cameras or block Wi-Fi networks
The most important method to counter radar jammers is operator training. Any system can be fooled with a jamming signal but a properly trained operator pays attention to the raw video signal and can detect abnormal patterns on the radar screen. The best indicator of jamming effectiveness to the jammer is countermeasures taken by the operator.

Example of a mobile phone jammer, produced by Jammerspro. A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting ...
Ukrainian National Guard personnel display drone jammers and a downed Russian Grifon 12 drone in 2022. During the first two days of the 2022 Russian invasion of Ukraine, Russian EW disrupted Ukraine's air defense radars and communications, severely disrupting Ukrainian ground-based air defense systems. Russian jamming was so effective it ...
