Home Area Network
HAN is short for Home Area Network. HAN is a recently coined term for a small LAN in a home environment, used for lifestyle purposes.

What are the functions of a Home Area Network?
The HAN connects all the sub systems in a Home and make them available for remote monitoring and control using the Internet. Your HAN could automatically turn devices on or off, up or down, and shift your smart appliances to an economy mode based on how you want to conserve energy. The smart meter infrastructure of today will help optimize your smart devices of tomorrow. But there are many devices and appliances in a home. Let’s look at the list of typical sub systems that the HAN would connect to and provide controls for:
Central Heating, Fire detection, Shade controls, HVAC, Lighting, Remote IR Control, Person Alarm and Monitoring (children, elderly, personell) , Burglar AlarM, Object Location Control, Weather station, Internet, VOIP, Solar Energy, Intelligent metering (Gas, Electricity and Water), Garden Irrigation controls, Door and gate controls, Window controls, Remote Appliance Control, Garden Lighting Controls, Swimming Pool Control, Indoor plants irrigation, Advanced light and climate controls, RF Chair, Shower Controls, Multi Media control, Touch Screen Monitoring and Control, Video surveillance and even more
Some Application Highlights:
Advanced Metering Infrastructure (AMM and AMI)
The Market Opportunity for Smart Meters and Home Area Networks (HANs)
Smart metering – the capability for automated, two-way communications between advanced utility meters and utility companies’ back-end IT infrastructure – promises significant benefits in operational and energy efficiency, environmental protection, and improved customer service. Regulation and legislation are encouraging the deployment of smart metering in multiple countries, states, and provinces. It will be the necessary to implement AMM in Europe in order to make it possible for consumers to choose their energy supplier, one of the key-issues of the European Union regarding an open market for energy.
How to build a Home Area Network?
The core of the HAN would be a Programmable Automation Controller that is capable of handling information requests from devices (M2M) and people as well as can take automated actions based on pre-defined parameters. To meet the different requirements of individual users and applications the device should have a modular design. A design with a base unit and expansion modules that can connect to sensors, counters, valves, home appliances and machines. It should have a built-in webserver that is simple to use and provides access to the data collected as well as functions for remote control.
Furthermore we need the software to access information and make remote monitoring and control possible. A web based service can provide an open system to set up devices in the HAN for remote monitoring and control.

The device supporting all this is the Home PAC 8000, a revolutionair design created to automate monitoring and control using all communications channels including wired Internet, GSM, GPRS, RF, and standards such as FRnet, MODbus, Zigbee etc. It has a built-in webserver and can be equipped with (low-cost) modules with analog, digital and relay input and output ports.
