Abstract: Systems and methods are described for determining a peripheral's location based on observations from a plurality of centrals. A central may periodically transmit its location and observations of peripherals to a backend. The backend may match the location of the central with one or more observations of a peripheral to estimate a location of the peripheral. The backend may receive observations of the same peripheral from a plurality of centrals. The backend may aggregate estimated locations to triangulate a more precise location of the peripheral.

Abstract: A method performed by an asset tracking device is disclosed to track an asset. The method comprises receiving, while operating in an extended discontinuous reception mode, a carrier messaging service message from a carrier network, transmitting a connection request to a management server to establish a connection with the management server in response to receiving the carrier messaging service message, receiving, from the management server over the connection, an instruction to use a specified backend check-in schedule until a specified condition is met, and responsive to receiving the instruction, using the specified backend check-in schedule to check in with the management server until the specified condition is met. The method further comprises reverting back to using a default backend check-in schedule to check in with the management server after the specified condition has been met.

Abstract: Systems and methods are described for transmitting broadcasts by Peripherals, receiving the broadcasts by Centrals, and communicating with a Backend by Centrals. Specifically, a Peripheral may generate and transmit an encrypted broadcast packet to a Central, the Central may transmit the encrypted observation information to the Backend, which may decrypt the broadcast packet. Additionally, a Central may transmit a request for authorization to connect to a Peripheral to the Backend. If authorized by the Backend, the Central may connect to the Peripheral. Further, a Central may receive a plurality of broadcasts over a period of time. The Central may store information about the broadcasts and, at the conclusion of the period of time, transmit the information about the broadcasts and the last-received broadcast to the Backend.

Abstract: Systems and methods are described for connection throttling between peripherals and centrals. Connections may enable bi-directional communication between a peripheral and a central to allow for updates to or configuration of the peripheral. The peripheral can send broadcasts to centrals. The broadcasts may contain metadata indicating a time period since the peripheral last connected to a central, a maximum connection distance, and a transmit power or signal strength indicator. The central may use the transmit power or signal strength indicator to determine a distance from the central to the peripheral and may determine whether the distance is within the maximum connection distance. The central may determine to connect to the peripheral based on time and distance thresholds being satisfied. Upon establishing of a successful connection, the central can update or configure the peripheral.
