1 Intelligent home networking Comfort Safety Energy Efficiency Self-determination

2 Application scenarios for home networking In many areas of everyday life a trend can be seen towards cross-linked devices. While only a few years ago the computer was a device that was connected to a printer, today it is often connected wireless to a DSL router, is part of an internal house computer network and in many cases already connected to the telephone system, the television and a hi-fi system. In future, more and more devices will have the basic capability to communicate with each other. The degree of networking will soon reach a new level. For the user, intelligent home networking opens up new services, improves the personal comfort, increases the security of the living situation, creates new means for saving energy and energy costs, and for the elderly to lead a self-determined life. Important home networking applications with their typical devices and the technologies used Applications Ambient Assisted Living Assistance systems for reminding, controlling, monitoring Medically motivated therapy and activity planning Internal networking Smart Home Smart Metering Consumer Electronics, Computer Networks Controlling domestic appliances, shutters, light etc. Monitoring doors and windows, control during vacations etc MP3 Energy management, controlling heating, domestic appliances and light to save energy Telephone, television, radio, photos, sharing videos/music, games etc. Running SoHo applications, using the Internet etc. Devices Motion detectors Light transmitters Smoke detectors Temperature sensors Window controllers Door controllers Home network Wireless technologies Bluetooth, DECT, RFID, WLAN, ZigBee, KNX etc. Wired technologies Ethernet, Powerline, KNX etc. Other networks elements, e.g. transmission media, memory, routers etc. Access technologies Wired & wireless technologies External networking

3 Smart Home Home automation and safety Living quarters reach a new dimension through intelligent home networking. The kitchen, for example, becomes a communication island, with domestic appliances centrally controlled by touch screens. Living rooms become adventure worlds with the help of innovative technology. The new generation of home control combines the entire control of the building with useful information and entertainment functions. The improvement in personal comfort is accompanied by an increasing safety comfort through a number of cross-linked sensors and devices. Burglaries, fire and water damage can be detected by a large number of different sensors and registered in the house and/or to an external alarm center. The simulation of your presence with time-dependend light and shutter controls protects you against intruders. The alarm system is automatically armed when you leave the house and lock the front door and is disarmed again when you unlock the house. Open doors or windows are signalized when you leave the house. Devices such as cooking plates or irons and unnecessary lights are switched off automatically as you leave the house.

4 Smart Metering Home Energy Management The recording of energy consumption of private households is more and more in the focus of politics and industry. The objective is to control energy consumption, to stimulate energy savings and to promote innovative technology in this sector. Currently there are approximately 43 million meters installed in Germany to measure electricity consumption. One million new meters are installed every year, either within the frame of new buildings or in the course of regular replacement. In accordance with the directive energy end-use efficiency and energy services (2006/32/EC, EDL directive) of the European Union, the customer should be able to transparently observe his energy consumption in the future under the term Smart Metering in order to use energy efficiently. In Germany, the national implementation of the EC directives is effected by the Energy Management Act (EnWG) and the Metering Access Ordinance (MessZV). As of January 1 st 2010, the operators of measuring points in new buildings and buildings that have undergone major renovation must install measuring equipment in accordance with 21b EnWG to reflect the actual energy consumption and the actual utilization time of the user of the connection. By December 30 th 2010 the electricity end user is also to be offered load-variable or daytimedependent rates in accordance with 40 EnWG as an incentive to save energy or to control energy consumption. 2-way communication Monitoring Intelligent domestic appliances Schematic view of the Smart Grid, Smart Metering and Smart Home Infee eeding by the supplier Internet Domestic electrical meter Intelligent energy management Smart Grids Smart Metering Smart Homes

5 Consumer Electronics and Computer Networks In the last few years, communication technology has become enormously important. Today we use the Internet as an information platform as a matter of course. 28 percent of Germans use a broadband connection. High bandwidths are the basis for new, innovative and user-oriented services. Internet television, voice over ip and MP3 downloads are further typical examples of the progressive convergence of various media. Example of networking between computers and consumer electronics Home server laptop / mobile phone Internet video game consoles MP3 Media server PC Embedded systems and network technologies Embedded systems play an outstanding role as key technical innovation drivers for the development of intelligent home networking. They are usually invisibly integrated in a technical environment in the form of processor hardware and software as well as sensor and actuator systems, are responsible for complex control and data processing tasks and introduce intelligence into the devices. Embedded systems are characterized by minimum costs, reduced space requirements, low energy consumption (often they even work independent of energy sources) and the low memory range of the processors. The connections between the abovementioned devices and their logical link-up to form an intelligent home network are ultimately effected by networking embedded systems. By definition, intelligent home networking does not stand for one isolated device. The definition of uniform interfaces and data formats, and the obligation to comply with them, is therefore indispensable
