Abstract: A wireless communication device may determine that a channel is to be used to transmit an advertisement. The wireless communication device may determine a channel-specific gain associated with transmitting the advertisement via the channel. The wireless communication device may generate the advertisement to include information identifying a channel identifier of the channel and the channel-specific gain. The wireless communication device may transmit the advertisement for locationing based on a received signal strength indicator (RSSI) of the advertisement.

Abstract: Devices and methods for using separate advertisement streams in a single beacon device are disclosed herein. An example beacon device includes at least one processor, a radio transceiver, and a memory. The memory may store instructions that, when executed by the at least one processor, cause the beacon device to receive a set of beacon information captured during a scan period. The instructions may further cause the beacon device to transmit a captured beacon stream (CBS) that includes beacon information from the set of beacon information. The instructions may further cause the beacon device to transmit, to a mobile device, a waypoint beacon stream (WBS) including a protocol data unit (PDU) data payload. The PDU data payload may encode a media access control (MAC) identifier adjacent to a type field indicative of a format for heartbeat data encoded in the PDU data payload.

Abstract: A method in a computing device includes: via a short-range interface of the computing device, detecting a plurality of beacons emitted by another computing device, each beacon containing an identifier of the other computing device; obtaining respective proximity indicators corresponding to the beacons; generating a first set of aggregated attributes from the proximity indicators; storing the first set of aggregated attributes in association with the identifier of the other computing device; and transmitting the first set of aggregated attributes to a server configured to detect physical proximity between the computing device and the other computing device based on the first set of aggregated attributes.

Abstract: A locationing platform may receive, via a mesh network, a locationing communication associated with a waypoint beacon. The locationing platform may identify an entry node of the locationing communication. The locationing platform may determine a waypoint location associated with the waypoint beacon based on locationing information in the locationing communication. The locationing platform may determine a node location of the entry node based on the waypoint location. The locationing platform may configure, based on the node location, a relay node of the mesh network to forward or drop subsequently received locationing communications that are associated with the waypoint beacon.

Abstract: Radio transceiver devices and methods are disclosed herein. An example transceiver device includes at least one processor, a plurality of radio transceivers, and a memory. The memory may store instructions that, when executed by the at least one processor, cause the transceiver device to cause the plurality of radio transceivers to scan over each of a plurality of advertisement channels during a first period; and during a second period of the scan period, cause the plurality of radio transceivers to scan over each of the plurality of advertisement channels. The instruction may further cause the transceiver device to receive a beacon data packet including beacon information that is associated with a beacon device disposed proximate to the transceiver device, and wherein the beacon data packet includes beacon information captured during the first period and the second period.

Abstract: A system for determining a distance between a receiver and a transmitter are disclosed herein. The transmitter includes a first antenna array having a first spatial orientation and is configured to transmit a signal. The receiver includes a second antenna array and an orientation sensor to determine a second spatial orientation of the second antenna array and is configured to receive the signal. A logic circuit is configured compare the first spatial orientation to the second spatial orientation to determine a relative orientation of the second antenna array; determine an angle of arrival of the signal; identify, based on the relative orientation of the second antenna array and the angle of arrival of the signal, a received signal strength compensation value; and calculate a distance between the transmitter and the receiver based on a measured received signal strength of the signal and the identified compensation value.

Abstract: A radio frequency (RF) device includes a spatial orientation sensor and logic circuit configured to determine spatial orientation of the RF device relative to a reference position or relative to a RF transmitter. In particular, the RF device determines a distance between the RF receiver and the RF transmitter based on a received signal strength of the signal and a determined spatial orientation of the RF device, by determining an orientation compensation value from a stored orientation compensation profile and determining a resulting compensated received signal strength. The RF device is thereby able to determine distance in an orientationally-invariant manner.
