Abstract :
The radio request of passive wirelessly interrogable surface acoustic wave sensors is discussed. The parameters of the measurement process are divided to the contributions of the sensor, the radio channel and the radio request method. The measurement bandwidth and an example for an actual radio channel are discussed. For matching of the method to the measurement problem, the parameters of different radio request methods are estimated
