Abstract: Methods of an access node of a wireless network controlling beacon transmission are disclosed. The method includes the access node detecting a presence of a client device, and the access node controlling air-time of beacon transmission based on whether the access node detects the presence of a client device.

Abstract: This application describes a system for contraband and weapons detection. The system comprises a coplanar sensor array, electronic drive circuitry, a data acquisition circuit, a video frame grabber, a video camera, and a computer control unit with a control module installed. Properly constructed and aligned, the system allows for the detection of very small magnetic moments, which surround ferromagnetic materials. This ferromagnetic detection allows users to screen personnel for contraband electronic devices and concealed weapons.

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.

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.

Abstract: A method and apparatus for controlling transmission air-time available to a wireless node within a wireless network is disclosed. The method includes occupied by transmission packets. The method includes the wireless node monitoring air-time available to the wireless node for wireless transmission. The wireless node controls wireless transmission of neighboring wireless devices if the air-time available is detected to be lower than a threshold.

Abstract: An apparatus and method of an access point suppressing probe responses is disclosed. The method includes the access point receiving a probe request from a client device. The access point determines a quality of a link between the access point and the client device based on the probe request, and the access point communicates to other access points, a client identifier and the quality of the link between the access point and the client device.

Abstract: An apparatus and method of an access node of a mesh network providing a client with wireless link quality information is disclosed. The method includes the access node receiving a probe request from the client. The access node generates a probe response to the probe request. The probe response includes an indicator of the received signal strength of the probe request, and at least one mesh network path quality parameter.

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.
