Next-generation fibre-optic broadband services in the UK will realistically average out at 45Mb, one expert says.
Broadband expert at UK Web Media, Tom Newton, has pointed to next-generation network in Japan and South Korea as evidence that 100Mb services rarely come near to their potential speed.
Mr Newton told Broadband Finder that users of next-generation services in the Far East regularly enjoy connection speeds up near the 50Mb mark, with a doubling of speeds possible in coming years.
He said: "In Japan anything below 40Mbps is considered to be 'slow'. If examples from both here and overseas are anything to go by, promises of 100Mbps or even 200Mbps seems to be just that."
Virgin Media has plans to offer its customers 50Mb broadband by the end of the year.
