Abstract
In general, in one aspect, the disclosure describes a narrow beam jammer to generate jamming signals for the regional cellular frequency ranges for use in vehicles. The narrow beam is directed at the location of the driver so that jamming and detection of communications is limited thereto. The initiation of the jammer may also be based on other parameters such as vehicle speed and Bluetooth synchronization. Other embodiments are described and claimed.
Claims17
A cellular device jammer integrated with a vehicle, comprising
- a jamming signal generator to generate jamming signals for defined frequency ranges associated with regional cellular communications;
- and
- a narrow beam antenna associated with the defined frequency ranges and directing a beam at an operator of the vehicle, to receive RF communications initiated from location of the operator and to transmit the jamming signal to the location.
