Abstract
A method of enabling at least some of plurality of nodes to join a wireless network, where each operates according to a wireless networking protocol and each is a component of a lighting system. An initiating unit wirelessly broadcasts a discovery request using a protocol of the network, according to which each other node only responds to the discovery request as broadcast from the initiating unit on condition of being within a predetermined range. Hence one or more in-range nodes each respond to the discovery request from the initiating unit and thereby join the network, while one or more out-of-range nodes do not respond. One or more of the in-range nodes also act as relaying nodes, to re-broadcast the discovery request for receipt by one or more of the out-of-range nodes. One or more of the out-of-range nodes respond to the re-broadcast discovery requests, thereby joining the wireless network.
