For example, in case of the information processing device 100 constituting a slave station, the control unit 160 is capable of acquiring predicted reception power of a desired packet transmitted from a master station connected to the information processing device 100 on the basis of a reference signal (such as beacon) transmitted from the master station. For example, reception power of a beacon (latest beacon) received immediately before (or value calculated on the basis of beacon) may be designated as predicted reception power. In addition, for example, average reception power of beacons in a certain period (or value calculated on the basis of average) may be designated as predicted reception power of a desired packet. In this case, an average may be calculated with lowered degrees of importance of old beacons, and raised degrees of importance of new beacons.
