New Fibre to the Premises (FTTP) broadband technology was demonstrated by Openreach to Councillor Jonathan Glanz, Member for West End Ward and lead member for broadband and connectivity on Westminster City Council.
Councillor Glanz helped an Openreach engineer, John Hilliard, 'splice' fibre optic cable in Clifford Street, and discussed how the technology works and the opportunities it offers for Mayfair's economic future.
Councillor Glanz said: "I am delighted that this new way of bringing fibre to the premises is being piloted in the West End and hope that it can be extended throughout the central area of Westminster to allow residents and businesses cost-effective access to ultra-fast broadband which they have long craved."
Andrew Whale, Chief Engineer for Openreach, said: "It's great to see the latest Fibre to the Premises (FTTP) technology being deployed using the new methods we have developed.
"Using micro cables, which are small diameter cables designed to get through busy underground ducts, we are able to avoid costly and disruptive civil engineering work. This in turn makes deployment much quicker and enables FTTP to be available to more customers. It's the first time that we've used micro cables in the West End."
Dr Prabhjot Basra, BT's regional partnership director for London, said: "This is great news for Mayfair. It is the latest development in our continuing drive to make faster internet access as widely available as possible. The faster broadband speeds will make the local businesses even more competitive, helping to secure and grow local employment opportunities."
Councillor Philippa Roe, leader of Westminster City Council and chair of the West End Partnership, said: "Providing modern broadband for businesses and residents in the heart of London makes a major contribution to our city's economic success.
"The West End Partnership and Openreach have been working closely to rollout superfast fibre broadband in Westminster and it is clear that this relationship is already bearing fruit.
"This does not mean we are resting on our laurels. The council's ambition is to see every Westminster business and resident connected to superfast and reliable fibre broadband, and we remain committed to come up with and support new ideas and innovations that will help us achieve this goal."
Openreach recently announced it will make fibre available for a further 360,000 homes and businesses in London in the next two years.
