Abstract: Disclosed is a system and method for determining output transmission power for radio signal transmission, from an interception transmitter and from an announcement transmitter, respectively, to at least one announcement receiver, wherein each announcement receiver is in a respective motor vehicle, the method comprising: receiving an input signal to be suppressed; determining a first field strength of the input signal, at a first frequency fI, at a position POSR; determining a first transmission power of a first radio signal, intended to be transmitted by the interception transmitter, needed to suppress the input signal at an interception transmission distance; determining a second field strength of at least one of atmospheric noise and the input signal at a second frequency fA, at the position POSR; and determining a second transmission power of second radio signal comprising an announcement to be transmitted by the announcement transmitter to the at least one announcement receiver.
