G.Fast technology is a faster version of DSL that can offer speeds of 1Gbps over a distance of up to 250 meters using copper. TeliaSonera has focused on TV and entertainment services, and the demand for capacity from customers is constantly increasing as a result. The field trial demonstrates that the G.Fast technology meets not only the requirement of current services, but also offers the bandwidth for future broadband and video services, such as 4KTV, which has four times the resolution of HDTV and consumes 100Mbps bandwidth per channel.
