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: 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: 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.
