摘要： A system for facilitating communications in a mesh network is provided. One or more devices of the mesh network may participate as routing nodes to provide range extension for any other devices in the mesh network that would otherwise be out of range from one another. In one or more implementations, Bluetooth Low Energy (BLE) may be used as the physical transport of the mesh network.

摘要： A monitoring device may monitor its proximity to a monitored station. The monitored station may transmit a proximity indicator to the monitoring device. For example, the proximity indicator may include the received signal strength of a signal sent by the monitored station. Wireless interface control circuitry at the monitoring device may monitor the status of the proximity indicator for changes. If one or more criteria set by an application processor are met by a detected change, the wireless interface control circuitry may send a status update to the application processor. In the criteria are not met, generation of the status update may be forgone. The application processor need not monitor the proximity indicator status and may remain in a reduced power consumption mode for longer periods.

摘要： In some aspects, the disclosure is directed to methods and systems for virtual angle-of-arrival (AoA) or angle-of-departure (AoD) tracking for virtually tracking multiple Targets. The wireless devices (e.g. Tracker and Targets) may participate in a mesh configuration and share data within the mesh. A first device may purport to be a virtual tracker, while acting as an AoA or Angle of Departure (AoD) Target. The devices being tracked (e.g. virtual targets), may instead operate as Trackers. Processor- and energy-intensive calculations may be distributed to the virtual targets and transmitted via the mesh for aggregation at the virtual tracker.
