A modular jammer designed for the 5400–5700 MHz frequency range is a radio frequency (RF) interference device focused on disrupting wireless signals operating in the upper portion of the 5 GHz band. This range includes part of the U-NII-2 Extended and U-NII-3 bands, widely used for Wi-Fi 5 (802.11a/n/ac) and increasingly for Wi-Fi 6 (802.11ax), wireless video transmission, and some drone communications.
