There are three types of WiFi jammers, 1 that can block satellite signals. The signal is always transmitted to the device on the ground (or in the air) at two main frequencies: the frequency GPS (civilian L1 band for trackers) is 1575.42 MHz. Frequency GLONASS (civilian L1 band for trackers): 1602 MHz. Because the frequencies are very close to each other, they are blocked by a broadband noise generator and only one antenna is required.

2. wifi jammer that can block the GSM channel segment will interfere with the frequency of mobile operators. Depending on the mode (3G, 4G) and standards (GSM, DAMPS, CDMA), operators can use different frequencies. Therefore, multiple antennas are connected to obstacles to close all areas, and these antennas can work independently.

3. Universal jammer. It applies to all frequency bands, such as mobile operators and satellite signals. It has multiple antennas for interference in selected areas. It also often offers the option of selective operation, the ability to generate noise only at selected frequencies.
