Cable networks could meet Europe’s Gigabit Society target within two years


Cable networks based on DOCSIS 3.1 technology


could help the European Commission achieve its Gigabit Society ambition eight years ahead of schedule and at a lower cost than fibre-to-the-premises (FTTP). That’s the conclusion of a report by telecoms consultancy Communications Chambers, commissioned by media multinational Liberty Global. The European Commission’s

Gigabit Society strategy lays out broadband targets of one gigabit to socio-economic sites, such as schools, hospitals and large businesses, and a minimum of 100Mb/s for all households, using technology that has an evolutionary path to gigabit speeds. The report finds that a range of technologies – including G.fast close to the end user, DOCSIS and FTTH – are capable of meeting these targets. Robert Kenny, founder of

Communications Chambers and co-author of the report, said: ‘Thanks to investment already under way by cable operators, gigabit broadband will be available to roughly half the premises in Europe by 2018 – far ahead of the Commission’s target of 2025. This will allow the Commission (and member states) to focus elsewhere, where interventions are necessary.’ FTTP and DOCSIS 3.1 aren’t


mutually exclusive – as described in our report ‘Cable Conundrum’ in Fibre Systems Spring 2015, which outlines the options for cable operators looking to upgrade their networks. Indeed, cable operators often choose fibre when expanding into new areas. However, DOCSIS 3.1 over existing HFC networks is in principle a cheap upgrade; Liberty Global expects it to cost $22 (€20) per home, according to the report. Such low costs mean that DOCSIS 3.1 is likely to see widespread deployment without any need for government subsidy.

The report warns that an


over-prescriptive policy focussed solely on FTTP risks jeopardising future investment. ‘The wrong intervention could be wasteful, or even damaging. For example, support for an expensive and slow-to-deploy technology could drive up prices and paralyse investment in other technologies which might have delivered improved performance more quickly,’ Kenny declared. He cites the situation in Australia, where the government’s original FTTP strategy – later transmuted to a mixed-technology approach – deterred investments by commercial operators in alternative broadband technologies in the short to medium term. The report was launched


alongside a new initiative by Liberty Global, called GIGAWorld, which outlines the operator’s plans to bring gigabit broadband speeds to customers in the 12 European countries in which it operates under the consumer brands Virgin Media, Ziggo, Unitymedia, Telenet and UPC.
