Wireless Transmission Device And Wireless Transmission Method

Abstract: This wireless transmission device is provided with: a wireless reception unit which receives wireless frames in which LAN signals which include timing packets and error detecting codes are multiplexed and converted into a wireless output signal from a wireless transmission channel and demodulates the frames and detects signal errors of the wireless frames on the basis of the error detecting codes within the wireless frames in order to calculate the wireless frame error rate; and a holdover switching unit which in the case that the wireless frame error rate exceeds a threshold switches from a timing recovery mode in which a clock and a timing pulse are output with a period and a phase which has been recovered from timing packets to a holdover mode in which the clock and the timing pulse are output with a period and a phase which had been saved at a time when normal.
