Appl. No.:

13/612730

Inventors:

Sandip HomChaudhuri - Santa Clara CA, US

Assignee:

Qualcomm Atheros, Inc. - San Jose CA

International Classification:

H04W 52/02

US Classification:

370311

Abstract:

A method of saving power in a wireless network can include determining a plurality of stations associated with an AP. The AP can create station groups using group selection logic. Notably, the group selection logic is transparent to the plurality of stations. A plurality of TIMs can then be sent, each TIM allowing only one station group access to a channel during a predetermined time interval, such as a beacon interval. In another method, a station can determine its sleep duration based on at least one of first information from the TIM to generate random sleep duration, second information regarding previous operation of the station, and third information regarding a status of the station. The first, second, and third information can include the number of stations associated with the AP and having buffered data based on the TIM, historical collisions, and power status.

Assignee:

Qualcomm Atheros, Inc. - San Joe CA

International Classification:

H04W 84/12

US Classification:

370338

Abstract:

Systems and methods are disclosed to provide a bridge for a wireless distribution system compatible with legacy equipment, including the use of a bridge device having two WLAN modules, with the first WLAN module associating with one or more stations and the second WLAN module configured to associating with a legacy access point. Frames received by the first WLAN module are forwarded to the second WLAN module for transmission and frames received by the second WLAN module are forwarded to the first WLAN module for transmission on the basis of address information in the frames.

International Classification:

H04L 9/00

US Classification:

380255

Abstract:

Systems and methods are disclosed to improve performance of a communications device receiving encrypted communications from multiple sources. The communications device is configured to increase the amount of decryption performed using a hardware-based process as compared to a software-based process by reprogramming the hardware to store a shared security key corresponding to a frame received from a source, allowing the hardware-based process to decrypt subsequent frames from that source.

International Classification:

G06Q 30/02

Abstract:

Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A request for content is received from a user device. A content item is identified for delivery to the user device responsive to the request. A location of the user device is determined. A threshold distance is determined that a user is likely willing to travel when visiting a physical location associated with the content item or content sponsor. A bounding region associated with the location of the user device is identified. Location extensions are identified that are associated with the content item. A determination is made when one of the location extensions is included in the bounding region and when a distance between the location extension and a current location of the user is less than the determined threshold distance. The content item is augmented with the one location extension.

International Classification:

H04L 12/741
H04L 29/12

Abstract:

Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes a first radio and a second radio coupled to a processing device. The processing device receives a request from a client consumption device via the first radio and determines a destination for the request as a second mesh network device. The processing device access a master routing table to determine that the second radio is to forward the request and forwards the request to the second radio. The second radio accesses a local routing table at the second radio to determine that a radio of a third mesh network device is a next-hop mesh network device in a first path to the second mesh network device. The second radio sends the request to the radio of the third mesh network device.

Abstract:

Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes multiple radios. A processing device of a first network hardware device scans a channel of the first radio for access point (AP) beacon frames that each contains information identifying a mesh network device in a WMN. The processing device creates a list of a plurality of mesh network device from the AP beacon frames and transmits a location probe transmission by each of the plurality of radios one sector at a time in a neighbor discovery process. The processing device receives metrics of the location probe transmissions received by the plurality of mesh network devices in the neighbor discovery process and configures each of the plurality of radios to communicate with one of a set of neighbor mesh network devices using the metrics in a neighbor selection process.
