Abstract: Disclosed is a wireless communication module capable of waking up a wireless communication device in a park state based on a connectionless broadcast and a method thereof. A synchronization information transmitting unit broadcasts synchronization information that includes an address of a personal area network user (PANU) and a clock information. A parameter setting unit sets window parameters that include size and repetition of a random access window. An information generation unit generates a window supporting information indicative of whether a random access window is supported or not. A window management unit activates and inactivates a polling access window and a random access window generated based on the window parameters. The PANU, which is synchronized using the synchronization information, is unparked through the random access window based on the window supporting information.
