Abstract
A short-range wireless communication device is disclosed that is able to ensure QoS of a communication and reduce power consumption by controlling allocation of a period occupied by the communication and by controlling a communication rate within the period occupied by the communication. The short-range wireless communication device receives or transmits beacons in a beacon period, allocates a communication-occupied interval in a super-frame between two adjacent beacon periods, and carries out a communication in the communication-occupied interval in conformity with a predetermined protocol. The short-range wireless communication device includes a control unit that dynamically sets and changes a communication rate in the communication-occupied interval and a number of slots constituting the communication-occupied interval.
