Abstract
A device and method for jamming wireless communication devices where the jamming signal is derived from the downlink signal of the base station and processed with a time delay sufficient length as to prevent the base station receiver from correctly processing the responding uplink signal from the targeted wireless communications device. Such wireless communication jamming device can be used by law enforcement and authorized government entities to block the operation of wireless communication devices such as cell phones within a target area.
Claims25
A method of jamming communication of a wireless communication device within a target area, the method comprising:
- receiving a target signal downlinked from a base station communicating within the target area,
- delaying the target signal to create a delayed target signal,
- amplifying the delayed target signal to a predetermined power level greater than the power level of the downlinked target signal as received from the base station,
- creating a jamming signal by amplifying the delayed target signal to the predetermined power level and sufficiently increasing the predetermined power level to a degree sufficient to induce the wireless communication device to lock onto the jamming signal, and
- causing the wireless communication device to uplink on a sufficiently delayed basis to be incorrectly processed by the base station.
A system for jamming communication of a wireless communication device within a target area, the system comprising:
- a jamming assembly including at least one jamming circuit comprising a signal delay device,
- a receiving antenna assembly disposed and structured to receive a downlinked target signal,
- said signal delay device operative to establish a predetermined delay in communicating the downlinked target signal,
- said one jamming circuit comprising a power amplifier operative to amplify power level of the downlinked target signal as received by receiving antenna assembly,
- a transmitting antenna assembly structured to emit jamming signal within the target area,
- said signal delay device, said power amplifier facility and said transmitting antenna facility collectively operative to create a delayed jamming signal having a sufficient power level to induce the wireless communication device to lock onto the jamming signal.
