Public wireless will serve 1.2m people in the West Yorkshire city centres.
Leeds and Bradford will soon each be getting a city centre network of free Wi-Fi hotspots.
Arriving early in 2013, and partly financed by the government's Urban Broadband Fund, it's part of a wider plan to create 'super connected' cities through public access to high-speed wireless.
Virgin Media Business will deliver the Wi-Fi - serving an estimated 1.2 million people across both West Yorkshire cities - using the same 4G LTE technology as successful trials in Bristol and Newcastle. It offers potential download speeds of up to 90Mb.
Councillor Keith Wakefield, leader of Leeds City Council, said: "I'm delighted our citizens, visitors and businesses will be among the first in the country to benefit from a free, fast, accessible city centre Wi-Fi service."
Leader of Bradford Council, David Green, added: "The super connected city initiative means a great deal for Bradford, as we're a growing city with a big economy. Local residents will be able to take advantage of the opportunities that enhanced broadband connections will bring."
The first hotspot locations will be the Briggate in Leeds and Bridge Street in Bradford, followed soon after by Millennium Square in Leeds and City Park in Bradford.
Leeds was recently named Britain's 'Wi-Fi Capital' by Sky Broadband, after it was found to have the highest proportion of people connecting to public wireless compared with other UK cities.
