Patent number: 11304163Abstract: A wireless communication apparatus includes a transmission/reception unit, a measurement unit, a physical layer, an acquisition unit, and a control unit. The transmission/reception unit transmits/receives packets to/from a communication peer. The measurement unit starts measuring a time period after a predetermined time from an end of the packet transmitted to the communication peer. The physical layer detects a synchronization code included in the packet transmitted from the communication peer and generates a synchronization detection signal. The acquisition unit acquires a measured value by the measurement unit when receiving the synchronization detection signal. The control unit has a function to change the physical layer to a physical layer with a different error tolerance, and calculates a propagation delay by subtracting a length of a synchronization code from the measured value and judges whether to update the physical layer or not depending on the propagation delay.Type: GrantFiled: August 26, 2020Date of Patent: April 12, 2022Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA ELECTRONIC DEVICES & STORAGE CORPORATIONInventor: Fumitoshi Hatori
