1. A method of commissioning a plurality of lighting devices in a lighting system, comprising:
disposing a plurality of locators at known physical locations within the lighting system;
providing a command to one of the plurality of lighting devices using a unique network address, wherein in response to the command, the lighting device transmits a packet having a constant tone extension (CTE);
using the plurality of locators to each determine an angle of arrival of the packet having the CTE;
calculating a physical location of the lighting device transmitting the packet having the CTE based on the angle of arrival determined by each of the plurality of locators; and
associating the unique network address with the physical location.
