Abstract: The present invention relates to a method of implementing a scatternet over a plurality of piconets using different frequencies in a Wireless Personal Area Network (WPAN). In the scatternet implementation method of the present invention, a master of a first piconet transmits a scatternet request to a shared slave, and the shared slave switches a frequency thereof to a frequency of a second piconet and relays the scatternet request to a master of the second piconet. The master of the second piconet transmits scatternet approval to the shared slave. The shared slave switches the frequency to a frequency of the first piconet, relays the scatternet approval to the master of the first piconet, and is allocated resources, which do not overlap each other, by the masters of the first piconet and the second piconet. The shared slave switches frequencies and relays data between the first piconet and the second piconet while synchronizing with both the first piconet and the second piconet using allocated resources.
