scope:

The rapid increase in the number of smart devices in the home, from entertainment systems to appliances and medical devices and the now near ubiquitous broadband connectivity have created a significant new potential market for service providers. However, in order to exploit this market and provide an integrated customer experience there is a central component which is still missing - a set of standards for the home gateway which will enable interoperability between smart home entities.

Defining smart home related standards for the home gateway can benefit the market in several ways:

• Avoiding duplication of hardware and software and the associated costs of having several disparate systems.

• Providing opportunities for new 'blended' services based on combining data from different HANs and appliances.

• Enabling automated, intelligent reaction to the environment - e.g. demand-side energy management.

The present document defines a smart home system architecture and derives requirements for the Home Gateway
