Broadband operator O2 has welcomed a report which suggested spectrum usage by telecoms groups should be capped.
An investigation by the Independent Spectrum Broker, revealed earlier this week, stated that network sharing may have to be enforced on internet service providers to ensure the government's Digital Britain plan is a success.
Under Digital Britain, every household in the UK would have access to a broadband connection with a speed of at least 2Mb.
Chief Executive of Telefonica O2 UK, Ronan Dunne, said: "Spectrum allocation is a complex question.
"Throughout the process we've looked for a solution that delivers the government's vision for Digital Britain, while ensuring we can continue to deliver a great customer experience."
Mr Dunne added that he was "pleased" with the discussions so far and that there could now be a wider debate on the plans.
Following the publication of the report, the government said it was preparing an official response to be announced next month.
