ABSTRACT:
A wireless communication apparatus capable of adjusting a time interval between slot sections in accordance with the amount of traffic in a piconet. The wireless communication apparatus has a transceiver for sending and receiving data to and from an external device, a beacon channel generator for generating a train of beacon slots during a park mode, with a constant interval, a slot section calculator for calculating the time interval of the trains of beacon slots consecutively generated based on a coefficient of slot utilization and a wakeup ratio, and a controller for controlling the beacon channel generator for allowing the trains of beacon slots to be generated at the time interval calculated by the slot section calculator. The beacon channel generator sets up an access window for activating the data communication with the external device, after the trains of beacon slots are generated. Accordingly, the wireless communication apparatus can cope with the change of traffic characteristics of piconet environment, as the time interval of the trains of beacon slots can be adjusted according to the coefficient of slot utilization and the wakeup ratio of the slot section.
