A wireless signal jammer is a device which blocks transmission by
creating interference. This wireless signal jammer can be categorized into the Radio Frequency (RF) jammer and GSM jammer.
A Radio Frequency jammer is a device used to disrupt or prevent communication via a broadcasted RF signal. It is an RF and GSM frequency disrupter commonly known as wideband radio frequency (RF) and GSM cell phone jammer. Simultaneously, they can blocks all commercial FM broadcast band (87.5 MHz to 108 MHz) and GSM signal transmissions within the jammer’s transmission range. The device can possibly block these frequencies by transmitting a dirty signal (like noise) on the same frequency at which the GSM and radio system operates.
A Radio Frequency jammer is a device that transmits a radio frequency signal on the same frequency at which the radio system operates and the jamming succeeds when the radio sets in the area where the jammer is located are disabled.
