BT has found a way to get ultrafast broadband speeds out of its existing copper network which could potentially save them billions of pounds in investment in fibre optic cable and offer a combined download and upload speed of 1Gb!
The new technology is called “G.Fast” and BT have done trials with it and had results showing download speeds of over 700Mb and upload speeds at 200Mb over a 66m distance. Over a shorter 19m length of copper the combined speeds are 800Mb download and over 200Mb upload.
Currently superfast broadband is delivered using FTTP (Fibre To The Premises) and FTTC (Fibre To The Cabinet), FTTC is the most widely installed option on BT’s network. However, this new “G.Fast” technology would be known as FTTdp (Fibre To The Distribution Point) and would see the fibre rolled out to telephone poles or junction boxes close to homes and businesses. Because the Fibre is at the telephone poles and junction boxes it usually means that it would be much closer to people’s premises than the street side cabinets meaning that there is less distance for the connection to have to travel down the existing copper network and thus meaning that faster speeds can be achieved.
Dr Tim Whitley, MD of Research and Innovation, BT Group said:
“We see G.FAST as a very promising technology with significant potential – that’s why we’re putting some of our best minds on the case to assess it fully in a purpose-built facility.”
“BT has a long history of pushing the boundaries in telecommunications, from the earliest days of the electric telegraph to today’s global fibre networks, and it’s crucial that we stay ahead of the curve for the benefit of our customers and shareholders.”
BT are soon to open their new ultrafast broadband lab in their research and development centre at Adastral Park in Ipswich where ongoing tests and technologies will be tried and tested.
