Abstract: In some aspects a first electronic device may detect a triggering condition for enabling control of a second electronic device. Upon detection of the triggering condition, the method can include determining an increased rate of transmission of advertising signals of a wireless protocol transmitted from a wireless transceiver of the first electronic device. The method can include transmitting a plurality of advertising wireless signals at the increased rate using the wireless protocol. The method can include receiving, from the second electronic device, one or more responses to the advertising wireless signals. The method can include determining a distance measurement based on the one or more responses. Responsive to the distance measurement being less than a threshold value, the method can include enabling control of one or more components of the first electronic device or the second electronic device by the other device. Numerous other aspects are described.

Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. Ranging between multiple mobile devices can present challenges due to clock drift between the devices resulting in missed messages due to collisions between ranging messages. Techniques can be implemented to reduce the number of collisions by designating time slots for ranging sessions based on timing from a coordinator mobile device. Alternative techniques allow for splitting up channels at different time amount different pairs of devices. The ranging techniques can be used to share information between devices with a predefined distance for applications such as augmented reality.

Abstract: Embodiments of the present disclosure are directed to, among other things, improving data security with respect to data collection, verification, and authentication techniques associated with obtaining and transmitting identity information. For example, an identification credential may be received (e.g., via a short-range communications protocol such as iBeacon) by a first device from a second device. The credential may be associated with a second user of the second device. The first device may verify the credential and, if valid, an additional option to approve a secure communications channel may be presented at the first device. If the additional option is selected, a secure communications channel may be established between the first device and the second device.

Abstract: Embodiments of the present disclosure are directed to, among other things, improving data security with respect to data collection, verification, and authentication techniques associated with obtaining and transmitting identity information. For example, an identity credential may be secured using biometric information associated with a user, the biometric information being obtained using a first biometric input method of a plurality of biometric input methods. When the user is later authenticated, the authentication may be based at least in part on determining that the user has selected a biometric input method that matches the biometric input method used to secure the credential as well as providing biometric information that matches the biometric information used to secure the identity credential.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a ranging protocol between two wireless local area network (WLAN) devices. In one aspect, the ranging protocol may be adjusted based on channel quality of a wireless medium between the WLAN devices. For example, a quantity of ranging frames and bandwidth for the ranging frames may be adjusted based on the channel quality. In some implementations, the channel quality may be determined using setup messages for the ranging protocol without a wireless association between the WLAN devices. The ranging protocol may be useful for range determination in an indoor environment where a WLAN is deployed. In some implementations, the ranging protocol may be used to determine a location of a WLAN device.

Abstract: Techniques disclosed herein are generally directed toward providing at least one security feature for an FTM session. More specifically, an initiating STA can include a security feature in an initial FTM request (iFTMR), determine whether a received FTM frame contains information responsive to the at least one security feature, and complete the FTM session accordingly (including terminating the FTM session if the FTM frame does not contain correct information responsive to the at least one security feature). Embodiments may include a security feature such as nonce values and/or generated (or partially-generated) media access control (MAC) addresses.

Abstract: In a procedure for determining distance (or angle) between a pair of electronic devices wirelessly connected to one another, a current session may be temporarily suspended on request and thereafter the current session may be resumed. Temporary suspension and resumption of the current session may, for example, eliminate starting a new session between the pair of electronic devices and repeating a determination of parameters that were initially agreed upon in the current session. Temporary suspension of a current session may be signaled wirelessly, by one electronic device to the other electronic device, for example, by setting a specific value in a specific field, to signal that the current session is to be paused now, in a frame or message transmitted from the pausing device to the to-be-paused device. The current session may be resumed without repeating determination of the initially-agreed upon parameters, by transmitting a frame to initiate measurement exchange.
