Abstract: PURPOSE: A mesh node synchronization method in a wireless mesh system is provided to modulate a preamble of a neighbor node and broadcasting information. CONSTITUTION: An automatic gain controller transmits a network setup signal received from a neighbor node to a PHY(PHYsical Layer)(S531b). The PHY synchronizes time or frequency by using a preamble of the network setting signal(S532b). The PHY transmits the location information of a starting point of a super frame of the network setting signal to a DSP(Digital Signal Processor). The DSP synchronizes the clock of a mesh node through the location information.

Abstract: PURPOSE: A super frame structure for mesh networking and beacon scheduling method is provided to easily adapt to the conversion of a network environment by executing a beacon scheduling in a distribution method. CONSTITUTION: A join node acquires the neighbor node beacon allocation information of the neighbor node from the beacon of the received neighbor node(S203). The join node selects an empty beacon slot(S205). A node selected by a beacon slot periodically transmits beacon to the corresponding beacon slot(S211). When the beacon is not received from the neighbor node, the joint node forms a network(S207). The joint node selects the beacon slot of a first super frame within space between beacons(S209).

Abstract: PURPOSE: A method and an apparatus for using a frame structure for a wireless mesh network are provided to transmit a network configuration information message and scheduling information for acquisition of resources with high opportunity. CONSTITUTION: A super-frame(SU,100) is the largest unit frame used for a wireless mesh network. Nodes within an OFDMA based wireless mesh network implement communication using the super-frame for data transmission and dispersed connection control. The super-frame comprises one or more frames, one of which is a network control frame(NCF) used by the nodes and the others of which are scheduling and data frames(SDF). The frame is composed of one or more subframes(SF).
