ABSTRACT:
In a method of selecting one or more transponders, the time duration of a reference interval is transmitted by the base station to the transponders in the header section of an information packet, each transponder compares the respective time durations of the reference interval and of a first time interval, and the further selection of the transponder depends on the result of the comparison.
