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: A method of transmitting universal serial bus (USB) frames over a communications channel is disclosed. A USB device receives one or more USB frames from a host device via a network, wherein the one or more USB frames are encapsulated in one or more data packets based on a communications protocol associated with the network. The USB device further synchronizes a local clock signal with a clock signal of the host device using a clock synchronization mechanism of the communications protocol. The USB device then determines a number of USB frames transmitted by the host device and processes the one or more USB frames based, at least in part, on the synchronized local clock signal. For some embodiments, the USB device may receive a frame count value and a corresponding media time value from the host device.

Abstract: In one example, a method includes receiving, by a wireless docking center (WDC) and from a wireless dockee (WD), a request to access one or more peripheral functions (PFs) associated with the WDC, and receiving, by the WDC and from the WD, one or more authentication credentials. In this example, the method also includes determining, by the WDC, whether or not the one or more authentication credentials received from the WD grant access to the one or more PFs to which the WD requests access. In this example, the method also includes permitting, by the WDC, the WD to access a first PF of the one or more PFs to which the WD requests access in response to determining that the one or more authentication credentials grant access to the first PF.
