ABSTRACT:
A wireless network system and a method of transmitting or receiving data over a wireless network capable of limiting transmission or reception of request packets by stations existing on the wireless network, where directional communication is performed in a high-frequency bandwidth, while a wireless network coordinator is being changed or while the wireless network coordinator is in a busy state. The wireless network coordinator includes a frame generation unit which generates a beacon frame for forming a superframe; a management unit which determines a state of a network and a wireless network station on the network, and inserts a result of the determination in the beacon frame, wherein the management unit sets a field of the beacon frame which indicates whether an accepting command which is transmitted by a station on or participating in the network can be received; and a communication unit which transmits the beacon frame.
