Patent number: 8559548Abstract: The radio communication device offers data communication with no adverse effect of EMI radiation. In response to EMI radiation detected by the radiation detector, the controller changes the normal communication mode into the avoidance communication mode. In the avoidance communication mode, the transmitter prepares a transmission packet so as to satisfy the following relational expressions: T1=T0/2/M and T2=T0/2 (where, T0 represents the cycle of an AC power source; T1 represents the transmission time; and T2 represents the transmission cycle). The transmission power changer determines the transmission power by multiplying T2/T1 to the transmission power in the normal communication mode. The transmission rate changer determines the transmission rate by multiplying T2/T1 to the transmission rate in the normal communication mode. The transmission packet is transmitted in synchronization with the stopping time of EMI radiation detected by the timing detector.Type: GrantFiled: August 26, 2010Date of Patent: October 15, 2013Assignee: Panasonic CorporationInventors: Yoshishige Yoshikawa, Katsunori Tanie, Hiromi Toyota
