A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. One mobile device acting as a beacon device can define a ranging round including an initial timeslot and a plurality of non-overlapping response slots for discovering and performing ranging with any mobile device in a vicinity of the beacon. The beacon can broadcast a ranging request including a beacon device identifier at a request time. A first mobile device can transmit a first acknowledgement message during a first response slot. A second mobile device can transmit a second acknowledgement message during a second response slot. The beacon device can calculate a first distance from the first mobile device and a second distance from the second mobile device based at least upon information in the first and second acknowledgement messages.

One to many ranging techniques

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.

Simulator for nearby interactions of devices

Systems, methods, and computer program products for determining a location from non-line-of-sight (NLOS) signals are described. A processor can determine that multipath interferences of a signal reaching a receiver through different paths that are close in lengths may be mistakenly interpreted as additional time shift, (e.g., additional time delay or, in some cases, time advance) of the signal in calculating a timing of the signal. The processor can determine the possible differences between path lengths and then determine an amount of the additional time shift. The processor can determine a shift correction to remove effects caused by the additional time delay from the timing calculation.

Correcting interference of non-line-of-sight signals

A method of sharing data is disclosed. A request from a client node to access data in a share associated with a server node is received. A communication from a management nexus is received. The communication includes a confirmation of an identity of the client node and a confirmation of an authorization for the client node to access the data in the share associated with the server node. The client node is allowed to access the data in the share associated with the server node based on the communication from the management nexus. However, the data is not sent to the management nexus.
