Abstract
An apparatus operable to disable operation of driver side 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 movement of a vehicle above a defined threshold. The active antenna element being mounted proximate a driver side seatback and/or visor. 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 driver side wireless communications device and a destination device.
