    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: Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. In one example, a first device may transmit a first packet via an NB signal to a second device, whereby the first packet comprises information indicating to the second device a time period for reception of a second (UWB) packet. In this example, the second packet may comprise a first partition and a second partition, whereby the first partition comprises a first plurality of fragments and the second partition comprising a second plurality of fragments. The respective fragments of each plurality of fragments may be transmitted via a UWB signal. The first device may then transmit the first plurality of fragments, and then subsequently transmit the second plurality of fragments to the second device, the first and second pluralities respectively being associated with different fragment types.

    Abstract: Systems, methods, and computer-readable medium are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. For example, a first device may schedule transmission of a packet via a narrowband signal to a second device. The first device may then transmit the packet, whereby the packet conveys synchronization data that is used by the second device to schedule reception of a plurality of fragments, respectively, via an ultra-wideband (UWB) signal. The first device may then schedule and transmit the plurality of segments to the second device via the ultra-wideband signals, each fragment being time-spaced from other fragments of the plurality of fragments by at least a predefined time interval.
