  • Patent number: 8730960
    Abstract: Described herein are techniques that provide for the transmission of a multicast stream that can resend frames that were not received using the partial state block acknowledgement mechanism. In an example embodiment, an access point reserves a channel for a transmission opportunity of a sufficient length to allow the sending of multicast data, block acknowledgement request, and receipt of a block acknowledgement. Optionally, the transmission opportunity may be of sufficient length to enable packets that re resent to be sent during the transmission opportunity, thereby preventing other stations on the channel from gaining control of the channel. Alternatively the access point may employ an appropriate backoff between TXOPs to AP prevent (T)DLS traffic to the recipients of the multicast stream. The access point does not send any frames from other queues during the transmission opportunity.

  • Publication number: 20140105395
    Abstract: In an example embodiment, a wireless device is operable to advertise a policy on the inclusion of the wireless device in a radio frequency map. For example, the wireless device map transmit a signal comprising a field in an extended capabilities information that indicates whether mapping of the wireless device is permissible. As another example, the wireless device may perform certain actions, such as changing media access control address, changing transmit power, and/or vary response times to prevent accurate mapping of the location of the wireless device.

  • Patent number: 8669902
    Abstract: In an example embodiment, there is disclosed herein, an apparatus comprising an interface and location determination logic coupled with the interface. The location determination logic receives data representative of measured signal strengths for a wireless device from a plurality of receiving devices at known locations via the interface. The location determination logic determines an estimated location based on the measured signal strengths and a first transmit power for the wireless device. The location determination logic determines a revised transmit power for the wireless device based on the measured signal strengths from the plurality of devices at known locations and the estimated location. The location determination logic determines a revised estimated location based on the measured signal strengths and the revised transmit power for the wireless device.

  • Publication number: 20130279349
    Abstract: Described in an example embodiment herein is a technique for generating a heat map representative of a radio frequency environment based on data representative of antenna pattern, antenna orientation, access point height and a path loss model. In particular embodiments, the base heat map can be corrected based on neighbor access point (AP) signal strength measurements, such as received signal strength indications (RSSIs) that are added over a base heat map. The neighbor RSSIs may be adjusted to a point underneath the AP.

  • Publication number: 20130064175
    Abstract: A wireless access point device configured to serve wireless client devices in a wireless network monitors transmissions sent by direct clients capable of forming ad hoc networks with one or more other direct clients. Profile data is stored for each detected direct client. The profile data indicates device type and services of the direct client, as well as potentially other information. The wireless access point receives from a direct client a request for information concerning one or more other direct clients, and sends a response to the direct client containing information for other direct clients based on the stored profile data.

  • Publication number: 20110176434
    Abstract: In an example embodiment, a wireless device is configured to associate with a first access point on a first frequency. The wireless device listens for a predefined frame, which may be sent by neighboring access points or other wireless devices. When the wireless device receives a signal comprising a predefined frame, the wireless device acquires a parameter, such as signal strength, for the signal. The wireless device sends the parameter for the signal to the first access point.
