Abstract
A power-saving mode flag generating unitsets a power-saving mode flag to active (non power-saving mode, turning on the power-source) when it receives a reset signal from a MAC unit. Furthermore, the power-saving mode flag generating unitsets the power-saving mode flag to sleep (power-saving mode, turning off the power source) in accordance with a signal-interrupt detection signal obtained by the signal-interrupt detecting unitof the packet monitoring unit. Depending on the state of a packet, the power-saving mode flag generating unitchanges the power-saving mode flag to active or sleep for the data communication area of the packet; however, for the ranging area of the packet, the power-saving mode flag generating unitalways sets the power-saving mode flag to active. A pattern discriminating unitdiscriminates between the data communication area and the ranging area of the packet.
