Title:
LOCALIZATION OF LUMINAIRES
Document Type and Number:
WIPO Patent Application WO/2009/104121
Kind Code:
A3
Abstract:
A node detection system includes an array of nodes (510), wherein each node of the array of nodes (510) has at least at least two, three or four directional antennas (530) configured to have antenna beams in as many directions. The range of each antenna is limited to reach a neighboring operational node of the array of nodes (510) for transmission of a message to the neighboring operational node. A controller (550) is configured to receive messages from the array of nodes (510) and determine the location of each node based on the messages.
