Inside a building, location-aware systems are required as alternative technologies to GPS for location-based applications, such as navigation services and robot controls. To solve this problem, the authors studied construction and maintenance method of buildings in which location information is liberally available to users throughout life-cycle of the buildings. This paper describes a new location-aware system based on RFID tags distributed in reinforced concrete slabs. This system is developed for buildings with bare concrete slabs such as manufacturing facilities and warehouses. To examine accuracy of location estimation, we implemented the system in about 200 m^2 of floor space in a multipurpose laboratory. As a result, the location estimation error was approximately 50mm on average. We also developed an inventory management system for a robot which automatically collects data such as IDs and current locations of materials and equipments.
