The disclosed subject-matter relates to a method for calibrating an onboard unit of a vehicle identification system, the method comprising: emitting at least one polling message from a first radio beacon; in the first radio beacon, determining a link margin of a communication with a first onboard unit by evaluating a response message of the first onboard unit to the polling message(s); and sending a configuration message from the first radio beacon or a second radio beacon to the first onboard unit or to a second onboard unit with a same characteristic as the first onboard unit to adjust a receive sensitivity or a transmit power of the first or the second onboard unit, respectively, to a level derived from the determined link margin. Alternative embodiments relate to a system and to an onboard unit used in the method.
