If we now understand how waves propagate in space and what happens when they meet, we can really understand how signal interference works.

Let's say we have a smartphone. These devices typically operate in a frequency range of hundreds of megahertz to a few gigahertz (which means their waves oscillate millions to billions of times per second, making them radio waves).

In order to block any cell phone / cell phone, a destructive signal jammer must be generated using the radio waves from that cell phone. Devices with radio interference actually saturate the room within a certain radius, with a radio wave precisely matching the frequency of the cell phone. The only difference between the two waves is that they are out of phase (inverted wave - see the pictures above).

The product of this activity is a "white noise" RF wave which destructively interferes with the waves of the cell phone signal jammer. Therefore every mobile phone in the affected radius shows an announcement "No signal".

The same principle applies to other forms of radio interference such as drone congestion, WiFi and GPS congestion, etc.

The Ninth Circle Court ruled a few days ago that it is perfectly legal for the police to attach a GPS tracking device to a person's vehicle without their consent or without an arrest warrant. The police could do this even if the person did not have a criminal background. This is alarming news for any free person who values ​​their right to privacy, and it allows the police and other government agencies to easily spy on anyone they choose without legal implications. Thanks to the GPS jammers available at the Jammer Shop, GPS tracking devices that are used to track and monitor the whereabouts of people can still be turned off. Among the various specialized GPS jammers made by the Jammer Store, the GJ6 jammer is probably the best. It can block any GPS device, thus protecting you from espionage. It's small, light, and easy to carry around like a commercially available handheld gps jammer. However, you can also plug the GJ6 jammer into the mains of any building or vehicle and use it like a standard desktop GPS jammer, which makes the GJ6 very versatile. The GJ6 jammer has a set of antennas that have been specially designed to produce an extremely strong jamming effect. The high-capacity rechargeable battery and built-in fan ensure that the GJ6 works long before it needs to be charged, and without overheating. A cell phone jammer with similar advanced features can also be purchased from the jammer shop.
