1 Motivation
The continuing demand for an ever-increasing device connectivity to offer new services to the customer and to optimize the installation and management of infrastructure will require the development of new networking technologies. As an example,
- The continuing customer demand for ever higher bit rate data services (e.g., QoS aware), high-speed Internet access and other innovative services, and the ongoing needs of network operators to leverage in-premises connectivity for distributing within the home IPTV and other applications.
- There is a growing interest worldwide in providing support for the integration of new technologies and applications aimed at sustainably addressing energy independence and modernization of the aging power grid, e.g., utility scale renewable energy sources, distributed energy resources, plug-in electric vehicles, and demand-side management. For supporting the above technologies and applications, it is necessary to ensure the availability of a modern, flexible, and scalable communications network that will tie together the functions of "monitoring" and "control." Information and communication technologies will allow utilities to remotely locate, isolate, and restore power outages more quickly, thus increasing the stability of the grid. Information and communication technologies will also facilitate the integration of time-varying renewable energy sources into the grid, enable a better and more dynamic control of the load, and will also empower consumers with tools for optimizing their energy consumption.
Whilst the focus of the group is in-premises networking, some technical developments may be needed to adapt these technologies to other contexts (e.g., access, industrial).
These new technologies will require the development of new Recommendations and enhancements to existing Recommendations covering all requirements and implementation aspects of new deployments. These studies will include, but are not limited to physical layer transport, the transport of higher layer protocols, the management and testing of in-premises systems, security aspects, spectral management aspects and energy saving techniques as well as the definition of communication network architectures and requirements.
The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility:

The target audience for this question are the technology suppliers, chipset vendors, equipment vendors, cable operators, service providers and utilities active in the domain of providing networking solutions for their users or infrastructures. A global audience will be targeted to facilitate a unified approach to support this broad scope of applications.
