G.hn (Gigabit Home Network) is a recognized term for the most advanced type of home networking technology. Its basic technical standards G.9960 and G.9961 were developed by the International Telecommunication Union(ITU) and promoted by the HomeGrid Forum industry association and other organizations.
Instead of high quality Ethernet cables, G.hn uses any kind of twisted pair and coax cables as well as power lines for data transmission and reaches comparable speeds.
The idea behind G.hn technology is that you can use your existing telephone and TV cables for home networking instead of having to equip the building with new Ethernet cables, which would require a lot of work and expense. G.hn technology is very easy to use - even for private consumers and technical laymen.
G.hn Standard is designed for the transmission of Ethernet packets of any kind. It can be used flexibly - even on the "last mile" for Internet connections.
The most important features of G.hn from the user's perspective are:
Advantages of G.hn compared to other technologies
By the way, the G.hn approach is not completely new. It is the successor of HomePNA - a standard for home networks via telephone and TV cabling developed between 1990 and 2009. HomePNA achieved data rates of up to 320 Mbps and was used extensively in the USA and several other countries. Many former HomePNA sponsors now support G.hn. In May 2013, the HomePNA alliance and the HomeGrid Forum merged. Meanwhile the association is called GiGA Wire Alliance.
