Abstract: Devices in a wireless network, such as wirelessly networked lighting devices, utilize two different types of radios, e.g. implementing two or more protocols such as Bluetooth and WiFi. Such radios operate in overlapping frequency bands of the RF spectrum. Time Division Multiplexing (TDM) of the two types of radio operations mitigates interference between the protocols competing in the spectrum overlap. In the examples with lighting devices, a driver of the light source provides a data bus that may be used as an auxiliary communications channel to implement TDM access by the radios to the overlapping frequency bands.

Abstract: Examples of a system and a method for asset tracking are provided. The system includes wireless communication nodes in a space that receive a basic message including an asset tracking tag identifier and a basic message sequence number transmitted by an asset tracking tag. The wireless communication nodes measure a received basic message signal attribute, and transmit a node asset message including the asset tracking tag identifier, the basic message sequence number, a node identifier, and the measured signal attribute of the received basic message to an edge gateway. The edge gateway may receive the transmitted node asset message transmitted by each of some number of the wireless communication nodes and rank respective node identifiers extracted from the received node asset messages based the measured signal attribute. The edge gateway forwards an aggregated message to a fog gateway for obtaining an estimate of the location of the asset tracking tag.

Abstract: A lighting system includes lighting devices and an update manager. The lighting devices include various hardware versions and/or functionalities. The lighting devices are queried to determine existing hardware versions and/or functionalities. The query is sent via a wireless mesh network of the lighting system. An Over-The-Air (OTA) update includes multiple different lighting device programming images, where each image corresponds to one of the existing hardware versions and/or functionalities. The OTA update is delivered via point-to-point connections between the update manager and some number of lighting devices and/or between the lighting devices. Upon receipt, individual lighting devices determine whether a lighting device programming image is needed and/or which of the lighting device programming images is appropriate.
