There's also a fresh, new standard that spans all wired media in homes, called G.hn (Gigabit Home Networking). Having one standard for powerline, coax, copper wire and plastic optical fiber allows vendors to make just one product for use with all those media, its backers say. G.hn is based on standards from the ITU (International Telecommunication Union) but doesn't interoperate with the technologies out there now. Last month, G.hn backers HomeGrid Forum announced they had issued their first certification of silicon. On Monday, Sigma Designs announced a G.hn chipset for distributing video, data and voice over coax, powerlines and copper wire. The company expects the CG5200 to be in volume production by the second quarter.
