Abstract
A radio communication apparatus includes a receiving section, a power supply section and a control section. The receiving section receives a radio signal when electric power is supplied, and the radio signal has a preamble field for storing a preamble pattern. The power supply section supplies the electrical power to the receiving section and stopping the supply of the electrical power in response to a supply stop signal. The control section generates the supply stop signal when presence of the preamble pattern can not be detected from the radio signal received by the receiving section, in a state in which a frame synchronization is established.
