Ofcom has re-affirmed its intention to offer a â€˜new framework for investment' in Britain's broadband networks. The media regulator has challenged the industry to back the proposed rollout of super-fast broadband networks across the UK. Ed Richards, Ofcom chief executive, outlined the proposals and stressed that a regulatory framework would be put in place that enabled operators to "make and keep a rate of return that is commensurate with the risks they are taking"."We want investment in a competitive environment," he explained. "Over the last few weeks there has been a step change in the level of interest and engagement on Next Generation Access issues from a range of companies and organisations."Ofcom plans to launch a new regulatory framework for super-fast broadband networks this September.
