Abstract: The present invention provides an OFDMA system based on a Mesh network. The OFDMA system comprises the Mesh network and several orthogonal and nonoverlapping data blocks divided on a time domain and a frequency domain. Several nodes are comprised inside the Mesh network, and each node is connected with one or more nodes. The data blocks are configured with a reserved gap in front of the time domain. Said several nodes include a control node to which synchronization signals corresponding to the nodes is accessed, so that the signals from the nodes are synchronized with that from the control node. The control node controls and coordinates transmission and scheduling of data blocks of the nodes with communication protocols; and the control node is used for controlling and managing data blocks required together in the Mesh network and their arrangement forms.

Abstract: The present provides a fast access control method of a wireless router based on a message authentication code (MAC) white list, which includes following steps: the wireless router entering into a creation mode controlled based on the MAC white list; the wireless router reducing its wireless signal transmission power; if there is a wireless terminal which attempts to connect to the wireless router in an effective period of time of the creation mode controlled by the MAC white list, storing MAC information of the wireless terminal in the MAC white list; when the effective period of time of the creation mode controlled by the MAC white list expires, completing creation of the MAC white list, and the wireless router restoring its wireless signal transmission power to a normal state. The method enables wireless terminals to quickly, conveniently and securely access wireless signals of the wireless router.
