Abstract: Location-based systems, such as a Real-time Location System (RTLS), are used to locate and track assets such as equipment, people, etc. In order to accomplish high accuracy in determining locations of assets (112-118), the information sent to the location server (108) from sensors (134, 138) should be accurate, relevant, sufficient, and timely. The limitations of a low bandwidth network between the sensors and the location server may pose challenges to reliably determining locations of assets. This invention is related to a hybrid lighting and location system (100), which involves the use of a system control device (106) and lighting devices (102, 104) that may include integrated sensors, transceivers, etc. Different embodiments are disclosed on apparatus, methods and systems to resolve the potential network congestion in such a hybrid system.

Abstract: A system for simultaneous control of a subset of nodes in a wireless network includes a network controller and a plurality of nodes that are communicatively coupled to the network controller. The network controller transmits a custom Zigbee unicast message to a node of the subset of nodes that is assigned as a point guard node upon receiving an instruction to control one or more nodes of the subset of nodes. The point guard node receives the custom Zigbee unicast message and generates an InterPAN broadcast message based on a payload of the custom Zigbee unicast message. The point guard node broadcasts the InterPAN broadcast message as a one hop broadcast message to all the nodes in the radio range of the point guard node. The receiving nodes whose identifiers are present in the payload of the InterPAN broadcast message act on the instruction to change a status thereof.

The user system can also receive, in response to the first initiation signal, a first response signal from the first transceiver of the first electrical device, where the first response signal includes a first identification of the first electrical device. The user system can further measure at least one parameter associated with the first response signal. The user system can also determine whether the at least one parameter is within a range of acceptable values. The user system can further assign the first electrical device to a first group when the at least one parameter is determined to be within a range of acceptable values.
