A cell phone jammer is a device that blocks signal reception between a cell phone tower and a cell phone. These devices were developed for the military and law enforcement, originally as a response to cell phone jammer. station signal. But the main problem is that Jammer cannot be detected. Threats such as unleashed explosives and hostage-taking. Low power jammers can block calls at a range of approximately 30 feet (9 m). Higher powered cells create a cell-free zone the size of a football field. Devices used by law enforcement can shut down service within 1 mile (1.6 km) of the device.

Can Police Detect Laser Jammers?

A laser jammer is a device that returns a "no response," or cosine error, when aimed at a vehicle with a police lidar gun. When a lidar gun shows this error, officers won't know if the vehicle is equipped with a laser jammer, or if they simply aren't targeting the vehicle correctly.

It is mainly used in prison cells, military installations and courts. With certain limited exceptions, use by federal law enforcement agencies is authorized under applicable statute.

What is the range of the jammer?

The range of an interfering device depends on its power source and location. Starting with portable jammers, jammers come in all shapes and sizes capable of jamming signals within a range of about 30 feet. For larger devices it can go up to 1 mile. When activated, the GPS jammers generates jamming signals within a 5 to 10 meter radius to interfere with the reception of GPS satellite signals.
