METHOD FOR RADIO COMMUNICATION BETWEEN A RADIO BEACON AND AN ONBOARD UNIT, AND RADIO BEACON AND ONBOARD UNIT THEREFOR

摘要

The invention relates to a method for selective radio communication between a radio beacon and an onboard unit of a vehicle passing the radio beacon. The method includes, in the onboard unit, determining the current heading of the onboard unit and transmitting information thereon to the radio beacon; and, in the radio beacon, checking whether the heading indicated in the heading information is within predetermined boundaries, and if so, carrying out a radio communication with the onboard unit. The invention further relates to a radio beacon and to an onboard unit for carrying out this method.
