2 Fraunhofer IIS Wireless Positioning and Communication Technologies 130 scientists/engineers in Nuremberg provide: n GNSS SatNav receiver technologies n Localization in WLAN-, DECT- and sensor networks n Different high resolution local positioning systems based on TOA, Phase or AOA n Inertial sensors, Sensor fusion n Wireless communication technologies: DECT, sensor networks, telemetry, n RFID n Applications in Production (Industry 4.0), Logistics, Automotive and Sports based on CPS
3 Smart Objects and Cyber-Physical Systems (CPS) Cyber-Physical-Systems Enabler for Smart Applications End of life Life cycle of the»cyber-physical System«Birth thing smart Smart Objects or Cyber-Physical Systems are based on microelectronical systems which n have their own identity, n create images of the real world based on different sensors, n analyze, store and process data describing the real world, n actively change reality using different types of interfaces and actuators, n use digital networks for communication between each other, with the environment and with the user himself, n use or offer globally available data and information services.
4 A pragmatic Framework for the Analysis and Design of Problem Solutions based on CPS Industry 4.0 and Cyber-Physical-Systems End of life Life cycle of the Cyber-Physical System Birth thing smart User Needs along the life cycle process Solutions delivered by different types of solution providers based on internet and Cyber-Physical Systems technologies The Internet of things IoT could be understood as the continuum of user-oriented problem solutions which are incorporating internet technologies as well as Cyber- Physical Systems Solution provider
