Abstract: A wireless transmission system includes an active wireless communication apparatus, a standby wireless communication apparatus, and a selecting apparatus for switching an operation. The standby wireless communication apparatus receives a signal transmitted from an opposing apparatus. When the standby wireless communication apparatus detects a failure information indicating that a failure has occurred in the active wireless communication apparatus as a result of reception, the standby wireless communication apparatus performs notification that the failure has occurred in the active wireless communication apparatus. The selecting apparatus that has received the notification performs switch control for switching the operation. Accordingly, it is possible to continue communication in a short switching time in case of a failure while maintaining high frequency utilization, for example.

Abstract: An outdoor fault monitoring device carries out radio maintenance communication with a maintenance terminal, positioned at a remote place, wherein a fault monitoring function part monitors occurrence/non-occurrence of a fault in a primary device function part. Upon detecting occurrence of a fault, the fault monitoring function part activates a radio maintenance communication function part. Alternatively, the fault monitoring function part deactivates the radio maintenance communication function part due to non-occurrence of a fault. In this case, it is possible to deactivate the radio maintenance communication function part upon detecting disconnection of a radio maintenance communication. Thus, it is possible to improve security against communication jamming created by a malicious person. Additionally, it is possible to suppress power consumption and to reduce a processing load by preventing unnecessary radio communication.

Abstract: A wireless LAN terminal (AP) transmits a data frame to a counter wireless LAN terminal (STA-j), and receives an ACK frame from STA-j. AP measures a response time from the transmission of the data frame to reception of the ACK frame, and measures a transmission interval time from the previous transmission of the data frame to STA-j to the current transmission. AP includes a memory to store a predetermined set transmission interval time and a set response time for said terminal station. AP re-transmits the data frame when the transmission interval time does not exceed the set transmission interval time and the response time exceeds the set response time, and stores the response time in said memory as the set response time, when the transmission interval time exceeds the set transmission interval time.

Abstract: In a wireless LAN communication system in which the data transmission rate is asymmetric between an upstream channel and a downstream channel, a wireless band is effectively used. The transmission rate of an ACK (reception acknowledgement signal) is variably controlled between an AP (Access Point) and an STA (mobile terminal station), based on the number of retransmissions of a user data frame. Specifically, control is performed as follows. The number of retransmitted frames is counted, and if the value is greater than a predetermined value M, which means that the transmission quality of an ACK is poor, the ACK transmission rate is brought one level down. The number of successive successful frames is counted, and if the value is greater than a predetermined value N, which means that the transmission quality is good, the transmission rate is brought one level up.
