Patent number: 9357481Abstract: In a wireless transmission device provided with an adaptive modulation circuit and a control method for the adaptive modulation circuit, an Ethernet signal received from a wired transmission path is transmitted to an opposite station one-to-one via a wireless transmission path and the Ethernet signal in the opposite station is again output to the wired transmission path. A traffic-statistics circuit which accumulates a traffic volume of a time zone-specific Ethernet signal as statistical data is provided. A wireless transmission capacity can be reduced by decreasing a multi-level number of a modulation scheme in a time zone in which the traffic volume is small based on the accumulated statistical data.Type: GrantFiled: June 7, 2012Date of Patent: May 31, 2016Assignee: NEC CorporationInventor: Kaichiro Saito

Patent number: 9032242Abstract: A link failure information transmission unit 130 of a transmission device 100 transmits link failure information indicating a fault in a link group to an opposing transmission device, upon detection of a fault in one or more of wired transmission lines belonging to any of link groups of the transmission device 100. Upon receiving the link failure information from the opposing transmission device, a link control unit 140 disconnects wired transmission lines included in a link group in the transmission device 100 corresponding to the link group in the opposing transmission device indicated by the received link failure information among the link groups of the transmission device 100. When the occurrence of a fault is notified in a system where transmission devices connected through an inter-transmission-device transmission line transmit signals of multiple wired transmission lines connected to the transmission devices, deterioration in communication efficiency of the entire system is avoided.Type: GrantFiled: October 28, 2011Date of Patent: May 12, 2015Assignee: NEC CorporationInventors: Motohiro Mukouyama, Kaichiro Saito

Patent number: 8761693Abstract: A traffic amount calculation portion calculates a traffic amount caused by transmission signals received by a transmission signal reception portion. An average traffic amount calculation portion calculates an average traffic amount that is an average of the traffic amount in a nearest predetermined interval. Further, a modulation method setting portion changes a modulation method used by a modulation portion based on the calculated average traffic amount. In addition, a transmission portion transmits transmission signals by using a transmission power amount corresponding to the modulation method used by the modulation portion.Type: GrantFiled: September 27, 2010Date of Patent: June 24, 2014Inventor: Kaichiro Saito
