Claim Text:
1. A wireless transmission device which transmits an Ethernet signal received from a wired transmission path to an opposite station one-to-one via a wireless transmission path and again outputs the Ethernet signal in the opposite station to the wired transmission path, comprising: a traffic-statistics circuit which accumulates traffic volumes of time zone-specific Ethernet signals and operation time zones corresponding to the traffic volumes as statistical data of traffic volume information indicating a correlation between the traffic volumes and the operation time zones, and generates statistical traffic volume information by calculating a most frequent traffic value of a predetermined number of identical time zones for each of the operation time zones based on the accumulated statistical data of the traffic volume information, the traffic volumes being varied for the operation time zones; and an adaptive modulation circuit which suppresses a wireless transmission capacity by decreasing a multi-level number of a modulation scheme in a predetermined operation time zone in which the traffic volume of the operation time zone corresponding to the predetermined operation time zone is smaller than a predetermined traffic value calculated based on the statistical data accumulated in the traffic-statistics circuit.
