Close to 70 percent of growth in Gigabit subscribers is expected to come from the Asia Pacific region.
Many leading markets will adopt G.fast broadband technology in the next five years, with coverage in some mature countries, potentially approaching 50 percent.
G.fast works best economically in a mature market with copper in the local loop, according to Point Topic, a fixed broadband analyst firm.
Broadband Forum CEO Robin Mersh said operators should take the picture painted by Point Topic as a clear call to action to consider G.fast deployments in their networks.
At the end of last year, the Broadband Forum launched its Broadband 20/20 vision which focuses on specific new broadband home and business opportunities that leverage SDN, NFV, Internet of Things (IoT) and enabled by ultra-fast technologies such as G.fast.
