## Abstract

Location-Based Addressing (LBA) is a method of controlling and commissioning networked lighting devices. The lighting devices communicate over a wireless network using radio frequency communication protocols. The lighting devices are commissioned or grouped based on their 5 respective locations in a building floor plan or a building architecture. The lighting devices are commissioned to respond to radio frequency communications that correspond to their respective locations. This imposed location-based architecture reduces the amount of transmitted data required to control the lighting devices and, thus, reduces the radio bandwidth required to control the lighting devices. In other words, controlling devices “multicast” instructions and controlled devices “listen” for instructions and act only upon instructions that correspond to their respective location. Hand shaking or two-way communication between the controlling devices and the controlled devices is not required.

## Claims

### Claim 1

A method for controlling one or more devices to be controlled within a control environment wherein each of the one or more devices to be controlled is programmed with one or more location descriptors that identify the physical location of each device and a floor plan of the physical location, the method comprising the steps:
transmitting a control signal to the one or more devices to be controlled containing a location based address that is an n-tuple that describes all or a portion of the control environment and uniquely identifies separate parts of the floor plan of the physical location and a function code; and
programming a playback device configured to store the location based address and function codes corresponding to a sequence of transmitted control signals over a selected time as a program;
wherein the playback device is programmed to transmit the program to the one or more devices to be controlled by sequentially transmitting the control signals over a pre-determined time period.

### Claim 2 (depends on 1)

The method of claim 1 further comprising the steps:
comparing the location-based address to the programmed location descriptors;
performing a function corresponding to the function code when the location based address matches one or more of the programmed location descriptors.

### Claim 3 (depends on 1)

The method of claim 1 wherein the location-based address is generated by concatenating a unique physical address onto a root location based address.
