Wales-based fibre-optic broadband provider H20 has announced that Dundee will become Scotland's first FibreCity.
The company plans to start work on the project - which will involve laying fibre-optic cabling in the city's sewers - in the next six months.
It is expected that residents and business will be able to benefit from download speeds of up to 100 Mbps.
Convener of Dundee city council's economic development committee Joe Morrow said: "This £30m private sector investment and other technological advances being pioneered in Dundee, cement the city's moves towards becoming a hub for information age products and services."
H20 said that businesses will be able to transfer files between multiple sites with no time lag, while households can look towards higher-quality services such as IPTV and video streaming enabled by the ultra-fast connections.
In early May, the company announced that Bournemouth will be the first UK city to receive the fibre-optic service. More than 88,000 homes and businesses in the area will be able to connect once work is completed.
