A system to provide privacy from third party vehicles includes a radio circuit configured to send a privacy indication in a beacon frame; and a movable device including a radio circuit to receive the beacon frame and a motor actuator controlled to comply with the privacy indication.

The use of shielded material in a deployable vehicle arresting and containment device that, when used for the interception of an unmanned vehicle, effectively achieves RF isolation of that vehicle, breaking all external communications with that vehicle. This apparatus, which may have internal and external antennas, could enable a variety of advanced effects such as localized GPS and command and control link spoofing and jamming as well as providing a vehicle for signal intercept and intelligence solutions. Additionally, due to the shielding properties of the arresting and containment device, semi-destructive means such as localized EMPs could be used to damage the encapsulated unmanned vehicle electronics.

A method for communication includes generating a data transmission for transmission to a target receiver, and generating at least one jamming transmission having an amplitude that changes multiple times during the data transmission. The data transmission is transmitted to the target receiver using an antenna array, and the at least one jamming transmission is simultaneously transmitted using the antenna array.

Methods and systems for generating and providing signals to a device, and configuring the device are disclosed. An example method can comprise identifying a device tuned to a first frequency, determining a signal configured to provide interference at the first frequency, and providing the signal to the device such that the device is caused to no longer be tuned to the first frequency.

Systems, methods and apparatus are described for a HERF weapon that may emit high-energy radio waves at a target based on locational information and a frequency associated with the target. The HERF weapon may receive the frequency and locational information from a sensing system. The HERF weapon may emit a high energy pulse toward the target and on the frequency associated with the target to disable or destroy the target without affecting nearby devices. The HERF weapon may allow the user to avoid detection by using a frequency that corresponds to the target's operating frequency.

A portable electronic device including a battery, a metal element, a control circuit and a plurality of impedance elements is provided. The battery is disposed in a carrier. The metal element receives a feeding signal through a feeding point to generate at least one radio-frequency signal.

The control circuit is configured to control the battery so that a plurality of operation signals are transmitted between the battery and the control circuit. The plurality of impedance elements are electrically connected between the battery and the control circuit, and the plurality of impedance elements transmit the plurality of operation signals and block the at least one radio-frequency signal.

An ultra-wideband high-power solid-state transmitter for electronic warfare applications which includes a plurality of wideband Gallium-Nitride (GaN) semiconductor monolithic-microwave integrated circuits (MMICs), a spatial power combiner to sum the aggregate contribution of the MMICs, a wide bandwidth small form factor driver amplifier module to supply the required gain in the transmitter, and a thermal management system.

A Wi-Fi controller identifies a rogue access point from AP scan reports and a rogue station from station scan reports. A connection between the rogue station and the rogue access point is disrupted by notifying a nearby, trusted access point to transmit a spoofed Basic Service Set (BSS) Transition Management Request (BTM-REQ frame) Action frame. In response, the trusted access point generates the frame spoofed with a Preference field value for a rogue BSSID set to a lowest value under a Subelement: BSS Transition Candidate Preference field, and also spoofed having a Preference field value for a trusted BSSID set to a highest value, and further spoofed with the Disassociation Imminent field value is set to 1 indicative of upcoming disconnection.
