WiFi jammers can disrupt communications

A wireless signal WiFi jammer is a device used to block the signal transmission of a device operating through signal reception. We seem to get rid of unexpected interference and live a safer life. Our mini phone jammer is wireless and portable. It looks like the shape of a mobile phone and is very portable. It can effectively block GSM and 3G signals as well as WiFi and GPS signals. After special adjustments, the following mobile phone frequency ranges can be destroyed: GSM (850-970 Mhz), GPS (1500-1600 Mhz), WiFi (2400-2480 Mhz). The wifi jammer emits low-power radio signals to cut off communication between the base station and all nearby mobile phones. But it will not interfere with mobile phones with a working radius of less than 10 meters! Moreover, its appearance definitely looks like a spy gadget. Moreover, it sells for only $99, so anyone can afford it.

The (usually deliberate) transmission of radio signals can disrupt communications by reducing the signal-to-noise ratio. The other type is unintentional interference, which occurs when the operator broadcasts on a busy frequency without first checking whether it is in use, or cannot hear the radio using that frequency. This can also happen when the device is transmitting a signal accidentally (for example, a cable TV device that is accidentally transmitting on the emergency frequency of an airplane). This concept can be used in wireless data networks to disrupt the flow of information. Some countries will use radio WiFi jammers to prevent foreign radio stations in border areas from reaching the country.
