ABSTRACT:
Provided is a wireless network system and a method for transmitting and receiving data in the wireless network, which have a particular time period for a beam search in a superframe thereof in order to enable stations, which carry out directional communications with a high frequency bandwidth, to efficiently perform a beam search. A wireless network coordinator in the wireless network system includes a media access control unit generating a beacon frame which constitutes a superframe including at least one channel time block; a bandwidth management unit setting a specific channel time block among the channel time blocks to a time period during which a packet for a beam search is transmitted and received among stations in a network; and a transmission unit transmitting the beacon frame having information on the setting through a predetermined communication channel.
