wifi jammer send electromagnetic waves at a frequency that will be broadcast throughout the area. The radio will cover and suppress the frequency band that receives this wave, thereby blocking the radio from broadcasting another band, making it impossible for the broadcast to correctly distinguish this band.
The transmission of radio signals disrupts communications by signal suppression. The other type is unintentional interference, when an operator sends a signal on a busy frequency without checking in advance whether it is in use, or cannot hear a radio using that frequency. Signal interference can also occur when a device accidentally transmits a signal. This concept can be used in wireless data networks to disrupt information flow. Some countries are accustomed to using radio interference to prevent foreign broadcasting stations in border areas from reaching the country.
