Zusammenfassung:	A method for synchronizing wakeup signals transmitted by a plurality of readers to at least one radio tag includes monitoring, by a first reader, for a first wakeup signal transmitted by a second reader. If the first wakeup signal is detected by the first reader, the first reader transmits a second wakeup signal having a duration ending at substantially the same time as the first wakeup signal. If the first wakeup signal is not detected by the first reader, the first reader transmits a third wakeup signal having a default duration. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
