• There are 5,600 telephone exchanges in the UK through which broadband reaches homes. But there are 150,000 power substations reaching around 98 per cent of homes. In many cases fibre could be strung up alongside power lines to homes instead of digging up roads.
• The UK has an extensive schools network with a Government requirement for each to have a minimum standard of broadband connectivity. Primary schools typically have 20 megabits per second and secondary schools 100 megabits. In some cases these are already being used to provide broadband to local councils, businesses and homes.
• At the same time hundreds of millions of pounds are being spent to upgrade health service networks, councils around the UK are planning network upgrades and the Department of Energy and Climate Change is co-ordinating an £11 billion smart metering programme which will entail physical installation visits to over 30 million households and businesses as well as an always-on communications network.
