A "low-rate" version of the original WPAN protocol was used as the basis of ZigBee. Despite originally being conceived as a standard for low power machine-to-machine communication in industrial environments, the technology has been found to be well suited for integration into embedded "Smart Home" offerings that are expected to run on battery for extended periods of time. ZigBee utilizes mesh networking to overcome the distance limitations associated with traditional WPAN in order to establish a single network of addressable devices spread across the entire building.
