Abstract
Detecting and jamming a wireless network using an intelligent jammer comprises determining that a signal source is an unlicensed signal source, synchronizing the intelligent jammer with the unlicensed signal source, determining a time and a frequency of a protocol signal associated with the unlicensed signal source, and transmitting a jamming signal according to the time and the frequency of the protocol signal. A system for detecting and jamming a wireless network comprises a first intelligent jammer, and an Intelligent Detection and Jamming Server (IDJS) coupled to the first intelligent jammer.
