Abstract
Provided is an operation method of a wireless personal area network (WPAN) device. In the wireless personal area network (WPAN) device, the WPAN device supporting a plurality of physical layer (PHY) communication modes determines timing for changing a PHY communication mode, with reference to a beacon frame, in order to communicate with devices using various PHY communication modes, and transmits information indicating a PHY communication mode as a parameter of a primitive to a PHY layer, at the determined timing.
