Abstract: Various aspects provide for receiving identity information from a station (STA) that identifies the STA as a sensor-type STA, determining whether communication attributes of the STA correlates with communication attributes expected for a sensor-type STA, and determining that the identity information received from the STA is false when the one or more communication attributes of the STA is uncorrelated with the one or more communication attributes expected for a sensor-type STA. Additional aspects provide for initiating one or more remedial actions upon determining that the identity information is false. The communication attributes may pertain to packet size, inter-arrival time, and/or inter-arrival time variance. The remedial actions may include blocking a future communication with the STA, communicating a warning message to the STA, and/or assigning the STA to a particular access window. Communications by the STA may comply with aspects of Institute of Electrical and Electronics Engineers (IEEE) 802.11ah.

Abstract: This disclosure relates to techniques for synchronizing playback of media data between a source device and one or more sink devices in a Wireless Display (WD) system. WD systems enable mobile devices to share a local display of the source device with remote sink devices. The techniques of this disclosure include a management procedure at the source device to select a universal queue size for the source device and the participating sink devices. The source device selects the universal queue size based at least on supported queue sizes of the source device and the sink devices. The media packets are then held in queues having the universal queue size at the source device and the sink devices. The uniform queue size combined with compensation for transmission delay enables each of the devices to begin processing the media packets at the same time.
