| 20080240017 | Method and apparatus of establishing connection in wireless local area network - An access point and a method to discover an associated station in a wireless network is presented. The access point scans the wireless network in order to discover one or more associated stations and establishes a connection with the discovered station. | 10-02-2008 |
| 20080240092 | ARRANGEMENTS FOR CONTROLLING MULTIPLE MAC INTERFACES - 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. | 10-02-2008 |
| 20080285536 | Method and apparatus for concurrent operation of wireless communication protocols - A method and apparatus of coordinating operation of two or more subsystems implementing different wireless communication protocols is disclosed. The method comprises coordinating operation of a first subsystem implementing a first wireless communication protocol and at least one other subsystem implementing at least one other wireless communication protocol by merging requests from the first subsystem for pre-scheduled access and real time access into a single request for access for the first subsystem. The method comprises merging requests from the at least one other subsystem for pre-scheduled access and real time access into a single request for access for the at least one other subsystem and arbitrating between the single requests for access for each subsystem to allocate access to the first subsystem and/or the at least one other subsystem. | 11-20-2008 |
| 20080287158 | Method and apparatus for multi-radio traffic arbitration in wireless communication protocols - A method and apparatus of coordinating operation of subsystems implementing different wireless communication protocols is disclosed. The method comprises coordinating operation of a first subsystem implementing a first wireless communication protocol and at least other subsystem implementing at least one other wireless communication protocol by arbitrating between conflicting real time requests for access from the first subsystem and the at least one other subsystem based on a respective type and priority of the requests. | 11-20-2008 |
| 20090034460 | Dynamic bandwidth allocation for multiple virtual MACs - Communication bandwidth on a single physical interface (PHY) in a wireless device is allocated among multiple virtual media access control layers (MACs) based on need. Excess bandwidth may be aggregated in a single virtual. MAC for power savings. | 02-05-2009 |
| 20090046673 | METHOD AND APPARATUS FOR IMPROVED DUAL CHANNEL OPERATION AND ACCESS POINT DISCOVERY IN WIRELESS COMMUNICATION NETWORKS - A method and apparatus of coordinating Time Division Multiple Access operation of wireless communication devices is disclosed. The method comprises an access point announcing a Quiet Period to one or more clients of the access point and transmitting as part of Target Beacons and probe responses an indication to the one or more clients that the access point will be absent from the communication channel for a period of time. The method also comprises the one or more clients establishing a connection with the access point after the Quiet Period when the access point is present on the communication channel on the basis of the indication. | 02-19-2009 |
| 20090052467 | METHODS, APPARATUS AND SYSTEMS CONFIGURED FOR HETEROGENEOUS SECURE ASSOCIATIONS IN WI-FI PAN - 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. | 02-26-2009 |
| 20090323570 | Techniques for management of shared resources in wireless multi-communication devices - An embodiment of the present invention provides an apparatus, comprising a network adapter configured for wireless communication using more than one technology, and wherein the network adapter is configured to share a plurality of shared hardware components by limiting access to the air to one comm only at given time by designating one comm that owns the shared hardware components as a primary comm and all other comms are secondary comms, wherein the primary comm allows the secondary comms to use the shared hardware components when it is in an idle-state but when the primary comm returns from the idle state, it claims ownership of the shared resources and the secondary comms release the shared resources. | 12-31-2009 |
| 20090327767 | Techniques for distributed management of wireless devices with shared resources between wireless components - An embodiment of the present invention provides an apparatus, comprising a network adapter configured for wireless communication using more than one technology using distributed management and wherein the network adapter is configured to share a plurality of shared hardware components by automatically turning all other comms to OFF when one comm is turned to ON. | 12-31-2009 |
| 20100075612 | Advertising desired range in a wireless network - 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. | 03-25-2010 |
