  • Patent number: 7801098
    Abstract: An integrated circuit radio transceiver and associated method comprises a multi-mode device operable to support personal area network communications as well as traditional wireless local area network communications. In one embodiment, IEEE 802.11 protocol IBSS communications are used to transport Bluetooth communication data packets. Thus, the multi-mode device is operable to establish traditional BSS communications with an Access Point in addition to establishing peer-to-peer communications with another multi-mode device to transport the Bluetooth communications over the 802.11 IBSS communication link.

  • Publication number: 20090235066
    Abstract: Aspects of a method and system for protected MAC sequence numbers, as well as secure block acknowledgment (block ACK) with protected MAC sequence number are presented. In one aspect of the system a communicating station (STA) may protect the sequence number (SN) field portion of transmitted protocol data units (PDUs), for example data MAC layer PDUs (MPDUs), or frames. In another aspect of the system, starting sequence number (SSN) information communicated via control frames, such as block acknowledgment request (BAR) and block acknowledgment (BA) frames, may be protected. In another aspect of the system, communicating STAs may exchange management frames to enable the protection of SN information in data MPDUs and/or the protection of SSN values in control MPDUs.

  • Publication number: 20080239988
    Abstract: Aspects of a method and system for network infrastructure offload traffic filtering are disclosed and may include a networked device, or station, which may communicate one or more filters to an infrastructure networking device. The infrastructure networking device may utilize the filters to implement filtering rules upon traffic received by the infrastructure networking device on behalf of the station. Based on the filters, the infrastructure networking device may determine whether to transmit received traffic to the station via a network, or whether to discard received traffic. The infrastructure networking device may perform traffic shaping based on the filters.

  • Publication number: 20080219196
    Abstract: Aspects of an infrastructure offload wake on wireless LAN (WOWL) are described. An aspect of the system may include a networked device, or station, which may communicate one or more filters to an infrastructure networking device. The infrastructure networking device may utilize the filters to perform pattern matching operations on frames or packets received from the network for delivery to at least the station while the station is in an inactive, or low-power, state. When pattern matching operations performed at the infrastructure networking device indicate receipt of a frame or packet on behalf of the inactive station, which matches at least one of the filters, the infrastructure networking device may store an indication value. The indication value may denote receipt of at least one frame or packet that matched at least one of the filters, which were communicated to the infrastructure networking device by the station.

  • Publication number: 20080175379
    Abstract: An integrated circuit radio transceiver and associated method comprises a multi-mode device operable to support personal area network communications as well as traditional wireless local area network communications. In one embodiment, IEEE 802.11 protocol IBSS communications are used to transport Bluetooth communication data packets. In another embodiment, a direct link comprising direct packet transfers without beaconing is performed between the multi-mode device and another multi-mode device. Thus, the multi-mode device is operable to establish traditional BSS communications with an Access Point in addition to establishing peer-to-peer communications with another multi-mode device to transport the Bluetooth communications over the 802.11 IBSS communication link or over an IEEE 802.11 direct communication link.

  • Patent number: 7197548
    Abstract: For each node, elapsed periodic time intervals are provided and counted since the transmission of a link integrity indication frame, a frame which can be received by all other nodes on the network and which contains a source identifier. Frames are received from a sending node and a node state status and a current received frame source address are maintained during each periodic time interval. Upon expiration of the periodic time interval, if the node state status is not indicative of network traffic and a count of the elapsed periodic time intervals since transmission of a link integrity indication frame is greater than a predefined count limit, a link integrity indication frame is transmitted.

  • Publication number: 20060173978
    Abstract: Methods and systems for enabling communication of information within a network are disclosed herein and comprise receiving at a first communication device located within a network, configuration information from a network service provider for configuring a plurality of communication devices located within said network. The first communication device located within the network can be configured based on at least a portion of the received configuration information. In response to a user input at a second communication device located within the network, at least a portion of the received configuration information can be communicated from the first communication device to the second communication device located within the network. The network service provider can be coupled to the first communication device via a wired connection. The network can comprise a wireless network.

  • Publication number: 20060083377
    Abstract: A method and apparatus for providing improved security and improved roaming transition times in wireless networks. In the present invention, the same pairwise master key (PMK) from an authentication server can be used across multiple access points and a new pairwise transition key (PTK) is derived for each association of a station to any of the access points. A plurality of access points are organized in functional hierarchical levels and are operable to advertise an indicator of the PMK cache depth supported by a group of access points (N) and an ordered list of the identifiers for the derivation path. Access points in each level in the cache hierarchy compute the derived pairwise master keys (DPMKs) for devices in the next lower level in the hierarchy and then deliver the DPMKs to those devices. An access point calculates the PTK as part of the security exchange process when the station wishes to associate to the access point. The station also computes the PTK as part of the security exchange process.

  • Publication number: 20060039305
    Abstract: Certain aspects of a method for enabling exchange of information in a secure communication network may comprise encapsulating authentication enablement information comprising data for configuring at least one 802.11 client station. One or more 802.11 client stations may be configured without disrupting access to any other 802.11 client station that is already communicatively coupled to the network. The encapsulated authentication enablement information may be authenticated using an extensible authentication protocol (EAP).

  • Publication number: 20060039341
    Abstract: Certain aspects of a method for enabling exchange of information in a secure communication system may comprise configuring at least one 802.11 client station via authentication enablement information comprising data that specifies a time period during which configuration is allowed. The data that specifies a time period during which configuration is allowed may comprise a configuration window open field, which indicates a period when a configuration setup window is open. At least one client station may be configured via the authentication enablement information comprising recently configured data, which indicates whether at least one configurator has configured at least one other client station within the time period during which the configuration is allowed.
