12 channel signal jammer
A 12-channel signal jammer is a device that can block or disrupt wireless communication signals across multiple frequency bands. It works by emitting radio frequency signals that are powerful enough to interfere with the targeted frequency bands, thereby preventing any communication from taking place within those frequency ranges.
Typically, a 12-channel signal jammer can block signals in a variety of frequency bands, such as:
GSM 900 MHz
GSM 1800 MHz
CDMA 800 MHz
CDMA 1900 MHz
3G 2100 MHz
Wi-Fi 2.4 GHz
