Abstract: A method includes receiving a first instance of code to be simulated for a first mobile device and a second instance of code to be simulated for a second mobile device, and generating, on a graphical user interface, a first representation of the first mobile device and a second representation of the second mobile device. When a request for a ranging measurement between the mobile device representations is received, a first pixel representative of a first location of the first representation and a second pixel representative of a second location of the second representation is determined, and a separation value between the first and second pixels is determined. A ranging value is determined based on the separation value and provided to the first instance of code in response to the request, thereby enabling the first instance of code to simulate a physical ranging measurement between two physical devices.

Abstract: Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for passive beacon communication techniques. Transmitting devices (e.g., beacons) can transmit advertising messages using a first wireless protocol to provide timing for ranging messages for one of more ranging messages over a second protocol (e.g., UWB). One or more receiving devices can determine using signal strength if the devices are within a threshold range to perform communication techniques. Various ranging communications techniques can be used to determine a range between the receiving device and transmitting device. Other techniques can be used to passively calculate the angle of arrival for transmitter signals. The angle of arrival information can be used for precise position locating for the receiving device or to indicate interest in information provided by the one or more transmitting devices.

Abstract: Certain embodiments are directed to techniques (e.g., a device, a method, or a non-transitory computer readable medium storing code or instructions executable by one or more processors) for many-to-many communication techniques for coordinating communications among a group of mobile devices that can be performed by a first mobile devices. The first mobile device can transmit a request to establish outgoing pairwise ranging sessions with other mobile devices of the group. Each of the mobile devices of the group of mobile devices can establish ranging sessions with the other mobile devices. Each mobile device can act as both an initiating device and a responding device for the ranging session. The first mobile device can detect one or more redundant ranging sessions the mobile devices. The first mobile device can identify whether to keep or terminate each of the one or more redundant ranging sessions based on a common criterion.

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.
