The expected roll-out of superfast broadband across the district is shown in this new map released by Leicestershire County Council.
Areas shaded in grey will benefit from faster internet speeds first, as private firms such as BT and Virgin Media bring the technology to those areas by 2016.
A £16.9 million contract between the council and BT will see the areas shaded green and dark green benefitting from the faster speeds by the end of March 2016.
It is hoped further investment will see the areas shaded in yellow given access to the improved speeds by 2018.
The council has stressed that the map – which covers the whole county – is not accurate down to home or postcode level but has been produced to give an indication of plans for the roll-out.
More detailed maps will be produced once BT’s planning and survey work has been completed.
Blake Pain, the county council’s cabinet member for economic development, said: This map gives an idea of how much of the county will benefit from the work we are doing with BT and the work of other providers, by 2016.
“It also starts to identify additional areas, where we are planning further investment to secure faster broadband by the year 2018.”
Last month the county council signed a deal with BT to bring faster broadband to rural areas.
The council is investing £4million as part of the deal, with £3.3m from the Government’s Broadband Delivery UK funds and £1.23m from the European Union.
BT is contributing a further £8.3 m.
The work will see phone exchanges updated to enable them to carry more data.
High-speed fibre optic broadband provides download speeds of up to 80Mbps (megabits per second) and upload speeds of up to 20Mbps.
The council says this means a music album can be downloaded in less than 30 seconds and a feature length HD movie in less than 10 minutes, while high-resolution photos can be uploaded to Facebook in seconds.
According to the regulator Ofcom, the current average residential broadband download speed in Leicestershire at the moment is 12.4Mbps, with 10 per cent of homes getting less than 2 Mbps.
BT’s local network brand Openreach will start survey work in the autumn and the first locations to be upgraded will be announced early next year.
The new fibre network will be open to all communications providers on an open, wholesale basis.
