There is a gps jammer that can only interfere with gps signals. But there are many jammers that will not only block gps signals, but also other signals, such as mobile phone signals, WiFi signals, Bluetooth signals, remote control signals, 5G signals, etc. This kind of jammer is a WiFi jammer, which can block many different signal frequency bands. It is also called a multi-power signal jammer.
The gps jammer was originally created by the government for military organizations and spy agencies. It is mainly used to confuse the enemy or interfere with the enemy's remote control missiles or bombs. This makes GPS jammers very popular, especially for high-power drone jammer equipment can intercept the WiFi GPS frequency band used by the drone, forcing the drone to lose its target, land or return to home.
GPS jammers are becoming more and more popular in commercial drivers. One of the most practical applications is the supplier or delivery driver. The supplier installs a GPS tracker on the vehicle to facilitate the acquisition of their location for real-time tracking and delivery. Drivers want to have lunch at their home or go home to find a forgotten item without having to do a lot of explanation because of GPS tracking on the vehicle. The range of most civilian GPS jammers is sufficient to cover the largest vehicles, providing users with a hidden and invisible environment.
