Abstract
A system and method for the commissioning of a lighting system is disclosed. The lighting system includes a plurality of lighting devices and a plurality of locators. Each lighting device includes a light emitting element and a wireless tag. After the lighting system is installed, each lighting device transmits one or more packets that contain a constant tone extension (CTE). This CTE allows the locators to determine the angle of arrival of the incoming packet. By combining the angles of arrival from several locators, it is possible to ascertain the physical location of the lighting device that transmitted the CTE. In this way, the physical location of each lighting device can be correlated to its network address.
