Aims of The Project
•To create a platform that will be able to sustain a wide rangeof applications irrespective of protocols and type of networksused.
•The platform must be able to support different bouquet ofservices for the benefit of the customers.
•Operation must be easy and secured with an appropriatequality of service.
•Both Home Control and Audio Video applications mustseamlessly co-exist on the same platform.
•To produce a demonstration system that will encompass thespirit of TEAHA.

Middleware - TAHI Open Architecture.
� « A description of methodologies of an open architecture for technology andservice delivery »
� The TAHI Initiative has defined an open architecture outline which providesguidelines on how to construct and deploy platforms for pervasive delivery ofservices.� Main features of the Architecture
� The recognition of entity groups in the delivery of a service that areinterdependent
� That each entity group will need (in sequence) an association with the nextone
� That each entity may be described in terms of an Object that characterises theparameters of that entity
� That any service will need Agents to negotiate between its source andrecipient entities, entity by entity
� That for some services the requirements of service delivery are different tothose that control the delivery

Development of a low cost RFcommunication solution
� To validate the usability of low-cost, low-power wirelessnetworking solutions (Zigbee) for future home applications.
� The Household Appliance Industry needs to improve the availablecommunication components to be used in a mass market.
� The Zigbee Alliance is defining an ultra low-cost, low-power wirelessnetworking solution, suitable for application such as remote control,home automation, toys and games, industrial sensors, meter reading…etc.
� Integration of TEAHA concept into one of the prominent RF solutions(Zigbee)

Development of an ultra low costpowerline communication solution
� To investigate, define and develop an ultra lowcost power line solution for seamlessinterworking
� Ultra-low cost powerline� In order to allow secure connectivity of some
devices, an ultra low cost solution consists inphysically separating network communicationfrom the device, by including very simplededicated connection from the device to thenetwork communication systems. (proxyapproach)
� investigate issues such as noise, compliance toEMC standards, coexistence with otherpowerline networks ….

The development of advancedresidential gateway subsystems
� To define and develop an end-to-end solution for the dynamicdelivery of managed services and applications into the home, basedon one or several Residential Gateway(s).
� Residential Gateway end-to-end solution� The end-to-end solution will encompass a RG, a Gateway Operator-
Aggregator, Service Providers.� Enhancements in the three main components (Addition of Business
Intelligence to the Aggregator, interconnection with legacy systems,exchange of information among subsystems by means of Web Services)
� Based on open architectures (TAHI)
