Abstract
An apparatus operable to disable operation of wireless communications devices, for use within a vehicle, includes a drive circuit coupled to at least one active antenna element to produce interference within at least one wireless communications band of frequencies in response to the wireless communications device transmitting at a transmission power above a defined power threshold for a defined amount of time. The interference may take the form of a bare carrier wave, or may take the form of noise, and is transmitted at sufficient power to interfere with communication between the wireless communications device and a destination device.
