Critics who claims that next generation G.fast broadband technology will fail to live up to expectations are wide of the mark, according to the Broadband Forum, which claims that new developments will offer unrivalled speeds and prove to a be a "giant step" for the industry.
Some pundits have claimed that the G.fast upgrade is simply another form of DSL solution designed to put off the major expenditure required to deploy a full fibre optic infrastructure such as fibre-to-the-premises (FTTP), and say it would also suffer from performance issues due to its reliance on legacy copper lines, to a certain extent.
Other concerns have been raised regarding G.fast’s power set-up, which operates by taking power from the customer's router, and the overall cost and difficulty of rolling it out, but these doubts are unjustified, according to CEO of the Broadband Forum, Robin Mersh.
He said that G.fast is a "giant step away" from DSL, capable of delivering download speeds of up to 800Mb, and will benefit from fast and cost-effective deployment.
It works in a similar way to BT’s existing up-to 80Mb capable fibre-to-the-cabinet (FTTC) solution that is currently being rolled out across the UK, though is designed to operate over copper lines shorter than 250 metres.
It is designed to work alongside solutions such as fibre-to-the-distribution-point (FTTdp) and fibre-to-the-remote-node (FTTRN), which would help to reduce the run of copper cable between street cabinets and homes by replacing more it with a fibre optic line, providing a major speed boost.
Mr Mersh added: "Those who think G.fast is just another DSL technology are way off the mark – G.fast is coming fast and it’s going to make an enormous difference for service providers and their customers.
"G.fast is borrowing the best from ADSL and VDSL to create a new generation of technology that is lower in power, more efficient, faster and easier to install."
The standard is currently going through its final approval process, which is set for completion by Q3 2014, with the first Huawei-based trials of G.fast taking place at the Adastral Park facility near Ipswich, where speeds of more than 800Mb have frequently been achieved.
