Abstract: A system and method for automated discovery of wireless locks in a security system allows installers to assign each wireless lock to a slot on a wireless hub that provides wireless communications to the wireless locks. Device controllers poll the wireless hubs to discover the communications paths to each wireless lock. The device controllers store the information obtained from the polling, and present the information to a control system that manages the wireless locks. This eliminates the current practice of manually updating assignment information on the control system between wireless hub slots and the wireless locks in response to additions, deletions, or relocations of wireless locks within the security system. This is especially useful in installations that include hundreds or thousands of wireless locks within office buildings, hotels, or conference centers.

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.
