GPS signal is the main way to control the UAV. Generally speaking, there is a certain distance from the control to the UAV in the signal propagation, and the signal is relatively weak at this time. Therefore, it is easier to use the drone jammer to counter the drone at this time, and it becomes easier to interfere with the GPS signal. Most consumer drones choose GPS signals for flight control, and these GPS signals are not encrypted, and drone jammer seize this vulnerability to take action. Currently, drones can land or return by sending strong jamming signals and suppressing control signals. by this principle. The device can be used after the drone is powered on to send jamming signals of all frequencies to the drone, allowing it to leave the operator's control and land automatically without receiving any control signals to keep the protected area safe.
Now, "no-fly zones" are set up in some of the secret areas. Many drone manufacturers have built-in components with "no-flying zones" that keep drones from flying in certain areas. Even flying into the "no-fly zone" from somewhere else will cause the drone to land itself automatically. To this end, as long as the drone jammer simulates the GPS ground signal and determines the geographic location, the drone can make a forced landing. At present, the domestic UAV jamming technology is still in the developing stage. Due to the continuous updating of UAV technology by UAV manufacturers, the current technology mainly uses signal shielding for UAV interference.
In order to have a communication equipment, we need a receiver and a transmitter. Interference is created by blocking the signal from the receiver. If the receiver signal is blocked, the IED (Enhanced Explosive Device) will not explode. The FCC tests and approves equipment used in correctional facilities. Hutchinson stressed that "this legislation will crack down on criminal enterprises and protect innocent victims and government officials from criminal harassment and threats." In fact, Texas state authorities said Richard Taylor (Richard Taylor Tabler) used a contraband cell phone to send threatening calls to state senators. In addition, authorities report that bold attempts, such as using slingshots to shove mobile phones through prison walls for unauthorized use by prisoners, are increasing.

When a wave jammer is used, the ability of prisoners to use cell phones is greatly reduced.
