  • Patent number: 7724683
    Abstract: Arrangements for controlling multiple media access control interfaces are disclosed. In one embodiment a method for controlling the interfaces can include setting up a transmission configuration for a first and a second media access control (MAC) interface, sending a transmission utilizing the first MAC interface and sending a transmission utilizing the second MAC interface. During subsequent communications communication performance parameters can be determined that are related the “multi”-MAC transmissions. Based on the communication performance parameters the transmission configuration of the first MAC interface and the second MAC interface can be modified to improve communication performance.

  • Patent number: 7697481
    Abstract: Embodiments of the present invention provide devices, systems and methods of seamless layer 2 handover between heterogeneous networks for a hybrid wireless communication device. For example, an apparatus includes a first wireless transceiver able to operate in accordance with a first wireless communication protocol, a second, collocated, wireless transceiver able to operate in accordance with a second wireless communication protocol, and possibly shared radio frequency components. A method includes a fragmented handover procedure in which a network entry procedure is divided into atomic operations which may be performed during short, orderly, absences from the active network. The method further includes orderly switching back to the active network for any data or connection-management transactions, until the fragmented handover is completed and layer 2 connections are established at the second network. Other features are described and claimed.

  • Publication number: 20100075612
    Abstract: In various embodiments, a network device may transmit its desired proximity range in the form of a proximity information element (IE) in a beacon or a request frame. The IE may contain threshold values for a Receive Channel Power Indicator (RCPI) and a Receive Signal to Noise Indicator (RSNI). Only devices that receive the beacon or request frame with measured signal values at least as great as the RCPI and RSNI values will respond. Devices that receive the beacon or request frame with measured values less than the RCPI and/or the RSNI should not respond, thus reducing the volume of communications on the network at that time.

  • Publication number: 20090052467
    Abstract: An embodiment of the present invention provides a method for heterogeneous secure associations in Wireless Fidelity Personal Area Networks (WiFi PAN), comprising designating as a regular mobile node (MN) a MN which establishes a security association with a PAN Master as it advertised by the PAN Master and designating as an outstanding MN as a MN which establishes a security association which differs from that advertised by the PAN Master; and differentiating by the PAN Master between subscribed and not subscribed multicast packets and if a currently processed frame is sent to a subscribed multicast address and both the Regular MN and the Outstanding MN are subscribed to the multicast address, then the PAN Master will convert the frame to unicast and will send to each subscribed Outstanding MN using its unicast security model and to regular MN as regular multicast frame.

  • Publication number: 20050070279
    Abstract: There are presented a method, device and system for selecting channels to be scanned by a wireless device that seeks to associate with a network. A wireless device such as for example a station 20 may determine the area in which it is located, identify channels used for association in such area and select such identified channels for scanning. The invention may order the identified channels for scanning based on prior associations of the station or based on characteristics of such channels or of access points transmitting on such channels. Such criteria may be collected and stored in an associative history of a station, which may include, for example, the time of past associations on a channel, the performance of an access point in prior associations or other criteria.

  • Publication number: 20040264413
    Abstract: A device, system and method for scanning channels on a wireless network. A device receives packets or other information for a channel and determines, from the received packets information regarding the channel. If the information indicates the channel is not desirable, before an informational packet (e.g., a beacon frame) is received, the device switches to a different channel for scanning.
