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.
