摘要： In a communication system in which a plurality of communication apparatuses form a wireless network and communicate with each other, a communication apparatus establishes timing synchronization by transmitting and receiving a beacon to and from other communication apparatuses. The communication apparatus determines whether or not beacon slots for transmitting the beacon are occupied, and if the beacon slots are occupied, connects to another communication apparatus without transmitting the beacon.

摘要： A wireless communication apparatus, which is capable of operating in an active mode and a sleep mode, comprises an antenna control unit, which controls a half-value angle and a directivity angle of an antenna for communication, and a mode control unit, which controls a change between the active mode and the sleep mode. When the wireless communication apparatus is in the sleep mode, the antenna control unit sets the half-value angle of the antenna to be a larger half-value angle than the half-value angle with respect to the active mode, and sets the directivity angle of the antenna to a predetermined angle.

摘要： A communication system comprises a control station and a child station. The child station decides a communication period between the child station and the control station in order to maintain a connection state in a power save mode. The decision of the communication period is performed in accordance with a predetermined wake-up period, a time-out value that maintains the connection state even when no communication is taking place, and a frame length that is a unit of the communication. The child station decides on the time-out value to be the communication period when the wake-up period is greater than the time-out period, and decides on the wake-up period to be the communication period when the wake-up period is less than or equal to the time-out period. The child station then transmits the decided communication period to the control station.

摘要： A communication terminal includes a first communication unit which has a power supply function by electromagnetic induction and writes or reads information in an active or passive mode, and a second communication unit having a communication capability higher than that of the first communication unit. A mode in which the first communication unit is functioning, the active mode or the passive mode, is determined. Communication via the second communication unit is controlled based on the determination result.
