"...the average speed of a UK broadband connection of 24 megabits per second (Mb/s)"
Hahahahahaha!!
Funny! Tell us another one!
Researchers from University College London's (UCL) Optical Networks Group have demonstrated a 1.125 Tb/s data transmission rate as part of their investigation into the capacity limits of optical transmission systems. Their study was published in Scientific Reports under the title "Increasing the information rates of optical …
Well, if you believe the Virgin Media junk mail then 24Mbits is akin to a snail crawling up a pane of glass?
OTOH, the BT Backhaul can't take even 10% of this so why are we even bothering to discuss speeds that will probably never be reached until 2116. Even then the last mile will still be over single strand twisted pair copper PSTN quality wire so anything over 80Mbits is more than could be expected even with a following wind and les than 50ft to the Fibre Box.
