IPTV was the primary driver behind the development of wired home networking technology, particularly when it was provided by a service provider as a triple play service, meaning it was supplied in addition to phone and data services like AT&T's U-Verse.G.hn-compliant devices with low-complexity profile implementations can also be aimed at smart grid applications like as demand side management or home automation.
1.IPTV:The IPTV set-top box is often not in close proximity to the domestic gateway that offers Internet connection in many customers' houses. When service providers begin to provide service bundles with numerous set-top boxes per customer, scenarios like this become increasingly typical. Using the current house wiring, G.hn is able to link the residential gateway to one or more set-top boxes. IPTV service providers do not need to set up new 802.11 wireless networks or Ethernet connections when using G.hn. End consumers may build the IPTV home network on their own because G.hn supports all types of house wiring, which would save the service provider money.
2.Home networks:G.hn is meant to be used in this application as well, even though WiFi technology is widely used for consumer home networks. G.hn is a suitable option for users in circumstances where connecting wirelessly is not required (connecting a TV or other stationary device to the network, for example), is undesirable (because of security concerns), or is not practical (because of the limited range of wireless signals).
3.Consumer electronics: Consumer electronics (CE) Products that use Wi-Fi, Bluetooth, or Ethernet technology can provide Internet connectivity. Many items that aren't typically connected to computers-like TVs and hi-fi systems-offer the ability to connect to a computer or the Internet via a home network in order to access digital material. High-speed connectivity to CE devices that can display high-definition television is the aim of G.hn. In CE devices, integrating the data and power connections may result in energy savings. Home theater receivers and other CE devices, which frequently operate on "vampire power" or standby, can save homeowners a significant amount of money if they use their power connection for data as well. This is because the device can be programmed to switch off when it is not showing any data.
4.Smart grid: G.hn can offer the communication infrastructure needed for smart grid applications since it can operate over wires, including AC and DC power lines. Reaching into every AC outlet in a house or building is necessary for a complete smart grid system to enable all devices to take part in energy-saving techniques. G.hn was included to the list of smart grid standards "for which it believed there was strong stakeholder consensus" by the US National Institute of Standards and Technology in September 2009, as part of an early draft of the "NIST Framework and Roadmap for Smart Grid Interoperability Standards".G.hn was taken out of the final "Standards Identified for Implementation" version in January 2010.
