Abstract: In a communication system, a first wireless communication apparatuses belonging to a communication group receives a connection request frame including a notifying security level from a second communication apparatus outside of the communication group. The first communication apparatus stores a reference security level peculiar to the communication group, which is selected from security levels depending on one of encryption methods including non-encryption and encryption strengths. In the first communication apparatus, the notifying security level is compared with the reference level, and a response frame including one of a connect rejection and a connection permission is described, is generated and transferred to the second communication apparatus. The connect rejection represents a rejection of connection to the second communication apparatus and the connection permission represents a permission of connection to the second communication apparatus.

Abstract: A communication device includes a receiver, a transmitter and an interruption module. The receiver receives an allocation signal indicating a first period usable by the communication device and a second period usable by a plurality of communication devices including the communication device. The transmitter transmits a transmission signal in the first period.

Abstract: A communication device includes a first receiver, a second receiver, a communication module, and a controller. The first receiver receives an operation signal from a remote controller. The second receiver receives a radio signal with a specific frequency. A power consumption of the second receiver is less than that of the first receiver. The communication module is capable of transmitting the operation signal to a first communication device. The controller controls power supply to the first receiver and the communication module and starts power supply to the first receiver and the communication module if the second receiver receives the radio signal. The communication module turns to a standby state if the first receiver does not receive the operation signal after start of power supply to the first receiver.
