Abstract
A sender communication device includes a communication unit for sending a communication signal to a receiver communication device, and a communication controller for controlling setting of communication channels used for the communication unit as well as for setting, when sending the communication signal, a sending period of the communication signal substantially not shorter than a receive confirmation period of all communication channels in the receiver communication device. A receiver communication device includes a communication unit for receiving the communication signal sent from the sender communication device while switching over plural communication channels, and a communication controller for controlling switching of the communication channels and for setting a communication signal receive-waiting opportunity, in which a first communication channel is used, substantially higher than a receive-waiting opportunity, in which a second communication channel is used. It is thus possible to avoid radiowave interference while saving electric power and lowering delay.
