  • Dual level prioritized vehicular repeater system
    Patent number: 5056152
    Abstract: A second level of vehicular repeater units is added to a conventional repeater system. The secondary vehicular repeaters may be specialized units, such as, motorcycle units that may be rendered inoperative due to battery drainage. The present invention provides that no secondary vehicular repeater shall transmit if a primary vehicular repeater is in the area. Only if there are no primary vehicular repeaters in an area will a secondary vehicular repeater transmit, and then, the present invention provides a prioritization arrangement so that no one secondary vehicular repeater is overly burdened by constant operation.
