The invention provides a method and apparatus for managing end nodes of a Low-Power Wide Area Network. A mode change command indicating a desire to switch the operating mode of each of a plurality of end nodes is broadcast. A determination is made as to whether all the end nodes have switched mode to match the desired operating mode, and the mode change command is rebroadcast if it is determined that not all end nodes have appropriately switched mode.

Controlling end nodes of a low-power wide area network

A receiver, method, terminal device, visible light transmissive structure and system for decoding light signals and light signals received in an area of overlap of light rays emanating from different lighting devices, each transmitting unique ID data. Light rays () entering the receiver () are optically spread apart in longitudinal direction (x) of an array of photodetectors (). The thus spread light rays () are optically diverged and spread further over the radiant active surface () of a particular photodetector (-), thereby optimizing the amount of light received at a respective photodetector (-).

Receiver, method, terminal device, light transmissive structure and system for visible light communication

This invention generally relates to commissioning in Zigbee Light Link (ZLL) networks. The proposed solution takes advantage of the existing Touchlink procedure in order to enable a controller device joining a ZLL network without having to Touchlink with every single lighting devices comprised in the ZLL network. This way, the one or more lighting devices of the ZLL network may be directly controlled by the newly joined controller device after a single Touchlink thanks to the introduction of a commissioning device. The commissioning device may be configured to provide specific joining information and binding information to the controller device. Further, a timer in the commissioning device may be triggered to lapse after a given period of time where the controller may be disconnected from the ZLL network.

Zigbee light link network commissioning

The present invention relates to a method and an apparatus for failure recovery in a network system, wherein a linked list is created, where each network node knows the network address of its neighbor node in at least one direction, wherein each network node sends a beacon to its neighbor node and has its neighbor node acknowledge receipt of the beacon, and wherein a network node checks with a switch device the port status of a port to which a neighbor node that has failed is connected in order to identify a replacement node.
