Apparatus and method for interfering with wireless communications devices in response to transmission power detection
First Claim
1. A method to disable operation of wireless communications devices within vehicles, the method comprising:
- determining whether a transmission power of the wireless communications device is above a defined power threshold;
determining a duration of time the transmission power of the wireless communications device is above the defined power threshold; and
driving at least one active antenna element to produce interference within at least one wireless communications band of frequencies in response to a determination that the transmission power of the wireless communications device is above the defined power threshold for a duration of time that exceeds a defined time limit.

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.

13. A method to disable operation of wireless communications devices within vehicles, the method comprising:
-
determining whether the vehicle is moving above a defined movement threshold; determining whether the wireless communications device is transmitting at a transmission power above a defined power threshold for a defined amount of time; and driving at least one active antenna element to produce interference within at least one wireless communications band of frequencies in response to a determination that the transmission power of the wireless communications device is above the defined power threshold for the defined amount of time while the vehicle is moving above the defined movement threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
