Moving from G.hn to G.hn Wave 2 at "up to 1 gig." G.hn has grown beyond home powerline into a legitimate contender for in-building broadband. KT, using Marvell chips has been offering hundreds of megabits since late 2014. KT reaches several million apartments now and intends to cover 95% of Koreans who can't get fiberhome by the end of 2017. That puts G.hn a year or more ahead of G.fast.
KT, working with Ubiquoss and Lightworks, has begun exporting the system. They have a deal with Turk Telecom and a demonstration building in Barcelona near Mobile World Congress. As you can see from their pr below, they plan a strong export campaign; the picture is the cover of their slick brochure.
G.hn is not as complex as G.fast with vectoring and many other features. That means it's simpler and cheaper. Chano Gomez of Marvell believes Wave 2 can match today's G.fast chips. I haven't seen test data from an independent source.
