A system is provided that includes first- and second-network subsystems. The first-network subsystem includes a first-network device with knowledge of its physical location and assigned logical address within the first-network subsystem. The second-network subsystem includes a second-network device initially without knowledge of its physical location and assigned logical address within the second-network subsystem. The second-network device has a known spatial relationship with the first-network device. The first-network device is configured to communicate its physical location to the second-network device, which is configured to derive at least partially its physical location based on the physical location of the first-network device, and the known spatial relationship between the first- and second-network devices. The second-network device is further configured to receive an assignment of its logical address within the second-network subsystem using its derived physical location.
