Many more UK homes and businesses look set to take advantage of i3 Group and Fibrecity's fibre-to-the-home (FTTH) broadband service in the coming year.
Consumers in Bournemouth and Dundee are already benefitting from the 100Mb next-generation services, but new Fibrecity networks are now being planned for Derby, Halton, Nottingham, Plymouth and York.
The urban areas will be included in an expansion programme designed to reach more than one million premises over the next four years.
Elfed Thomas, Chief Executive of i3 Group, said the firms are moving forward with plans to bring open next-generation internet connectivity to homes across the UK.
"The antiquated copper 'last mile' is the biggest problem for connectivity speeds, slowing them down significantly by the time the network reaches the home and the consumer is trying to access services," he commented.
"Only a true FTTH connection will ensure we have a solution that will see us through several decades rather than being outdated in a few years."
Some 35,000 consumers in Bournemouth have already signed up to the pioneering 100Mb broadband service, which also has the capacity to provide temporary 1Gb bursts for instant downloading.
