The main driving force behind wired home networking technology is IPTV, especially when service providers offer it as part of a triple-play service, including voice and data services, such as AT&T's U-Verse. Smart grid applications (like home automation or demand-side management) can also be targeted for implementing G.hn-compatible devices with low-complexity profiles.
1.IPTV: In many customers' homes, the residential gateway that provides internet access is not located near the IPTV set-top box. This situation has become quite common as service providers start offering service packages that include multiple set-top boxes per user. G.hn can connect the residential gateway to one or more set-top boxes using the existing home wiring. With G.hn, IPTV service providers don't need to install new Ethernet cables or 802.11 wireless networks. Since G.hn supports any type of home wiring, end users can install IPTV home networks by themselves, thereby reducing costs for service providers.
2.Home Networking: Although Wi-Fi technology is very popular in consumer home networks, G.hn is also suitable for this application. For consumers who don't need to use wireless (such as when connecting fixed devices like TVs or network-attached storage devices), don't want to use wireless (for security reasons), or find it impractical (such as due to limited wireless signal range), G.hn is an appropriate solution.
3.Consumer Electronics: Consumer electronics (CE) can use technologies such as Wi-Fi, Bluetooth, or Ethernet to support internet connectivity. Many products traditionally unrelated to computer use (such as TVs or hi-fi equipment) offer options to connect to the internet or a computer using a home network to access digital content. G.hn is designed to provide high-speed connectivity for CE products capable of displaying high-definition television. Integrated power and data connections can save energy for CE devices. Given that CE devices (like home theater receivers) are often in standby or "vampire power" states, if the homeowner's power connection also serves as a data connection, this would result in significant savings for the homeowner-the devices can reliably turn off when not displaying any source.
4.Smart Grid: Since G.hn can operate over electrical wires, including AC and DC power lines, it can provide the communication infrastructure needed for smart grid applications. A comprehensive smart grid system requires access to every AC power outlet in the home or building so that all devices can participate in energy-saving strategies.
