  • Patent number: 8340054
    Abstract: An apparatus and method of a wireless network timing transmission of multiple BSSID beacons is disclosed. One method includes a method of a wireless access node within a wireless mesh network timing transmission of multiple BSSID beacons. The method includes the access node identifying multiple personalities of the wireless mesh network, wherein a separate MAC address corresponding with each of the personalities. The access node assigns a beacon type for each of the personalities. During each transmission frame, the access node consecutively transmits a plurality of the beacon types, wherein the different beacon types are consecutively spaced during transmission by a predetermined period. The predetermined period is substantially less than a time duration of each transmission frame.

  • Patent number: 7983225
    Abstract: An apparatus and method of a wireless network timing transmission of multiple BSSID beacons is disclosed. The method includes identifying multiple personalities of the wireless network, wherein a separate MAC address corresponding with each of the personalities. A beacon type is assigned for each of the personalities. During each transmission interval, a plurality of the beacon types are consecutively transmitted, wherein the different beacon types are consecutively spaced during transmission by a predetermined inter-frame spacing, wherein the predetermined inter-frame spacing is substantially less than an air-time duration of each transmission interval.

  • Patent number: 7924749
    Abstract: An apparatus and method of identifying long links within a wireless network is disclosed. The method includes identifying long links within a wireless network. The method includes a first node estimating a link quality of a wireless link between the first node and a second node of the wireless network. The first node uni-casts packets to the second node. The first node monitors a packet acknowledgment success rate. The first node identifies the wireless link to be a long link if the link quality is above a link threshold, and the packet acknowledgment success rate is below an acknowledgment threshold.

  • Publication number: 20070201393
    Abstract: A method of optimizing link transmission parameters between access nodes within a mesh network is disclosed. The method includes each access node within the mesh transmitting packets at N different combinations of data rates and power levels. Each receiving node that receives the data packets at one or more of the N combinations, selects a most desirable one of the received combinations. The receiving nodes indicate to the transmitting nodes the selected most desired combination for transmitting to the receiving node.
