GPS jamming is the use of frequency transmission devices to block or interfere with radio communications. The types of communications that could be disrupted include phone calls, text messages, GPS systems and Wi-Fi networks. The devices are tailored for consumers who want to ensure privacy or prevent tracking. However, without proper technical knowledge or in the wrong hands, GPS jammers can cause potentially damaging communication disruptions.
The GPS jammer is usually a small, independent frequency transmitter that can send jamming signals within a range of 5 to 10 meters. The device is usually plugged into the vehicle's cigarette lighter or USB/charging port, and requires a small amount of power. Although illegal in many places, you can purchase various types of GPS jammers online, including Wi Fi jammers, Bluetooth jammers, remote jammers and UAV jammers.
