Abstract: Systems and methods of limiting wireless discovery range are described. A method may include determining, at a first device, a discovery range threshold that limits a distance from the first device at which a second device is operative to decode a discovery message. The method may include adjusting a transmission attribute at the first device based on the discovery range threshold. The method may include sending the discovery message in accordance with the adjusted transmission attribute.

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.

Abstract: Techniques are provided for validating a mobile device in a passive digital key system. An example method of validating a mobile device includes determining a positioning measurement for the mobile device relative to a reference point, obtaining a measured distance with at least a first transceiver, obtaining a calibration distance based at least in part on the positioning measurement for the mobile device, computing a validation distance based at least in part on a difference between the measured distance and the calibration distance, and validating the mobile device based at least in part on a comparison of the validation distance and a threshold value.

Abstract: In one example, a method includes performing, by a wireless dockee (WD), a plurality of operations to wirelessly dock with a wireless docking center (WDC) such that the WD may access one or more peripheral functions (PFs) associated with the WDC. In this example, the WD includes a docking service, an application service platform (ASP), and one or more peripheral services that each correspond to at least one PF of the one or more PFs associated with the WDC. In this example, the method also includes interfacing, by the docking service and with the ASP, to perform a first subset of the plurality of operations, and interfacing, by the docking service and with the one or more peripheral services, to perform a second subset of the plurality of operations.
