Equipment designers and manufacturers need a standard interface specification, which has been agreed to by the service provider, customer premises equipment, and home automation industries.
In-home networks need to be integrated with each other, and integrated with access networks, enabling new differentiated services.
Homes need to be more cost-effectively managed. The lack of a standard has prevented widespread innovation of products and services.
A given residence will have a broadband service provided by a telephone carrier, a cable TV service provider, a utility company, and/or a wireless communications provider through copper wires, hybrid fiber coax, RF transmission, or fiber to the curb (including any combination of these sources and structures). The authors of this document believe that it is essential to develop a set of interface standards between the broadband residential access network(s) and the communication services (the "in-house" networks) required by the residence.
As previously stated, this document will not define a specification, but lay out the concept and design principles. We call this interface between the access network and the residential services the Residential Gateway (RG).
