IN-VEHICLE CELLULAR DEVICE BLOCKER TO RESTRICT CELLULAR USE FOR OPERATOR

摘要

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.
