WIPO Patent Application WO/2006/103888

A1

A directivity communication apparatus or the like achieving a low power consumption. A communication system using the directivity communication apparatus or the like. A directivity communication apparatus or the like attempting to shorten the time until a communication establishment following a communication resumption. A communication system using this directivity communication apparatus or the like. A directivity communication apparatus comprising an antenna the directivity of which can be controlled; an information storing part that stores a communication history for determining communication conditions during communication; and a control part that controls, based on the communication history, the antenna so as to enable communication with the other end of communication described in the communication history; wherein a motion vector is calculated from the communication history to estimate the movement position of the other end of communication and further estimate an optimum communication condition, thereby resuming the communication.
