A year-long trial of a new free WiFi network is being launched today by Connecting Cambridgeshire and The University of Cambridge.
The new network will be ready for when the Tour de France comes to Cambridge on Monday 7 July.
The free WiFi will allow people to keep up-to-date with friends, work or study on the move, and share their experiences of events such as the Tour de France.
The service is being provided through BskyB-owned The Cloud, which has over 22,000 hotspots across the UK.
Cambridgeshire County Council, Cambridge City Council and the University of Cambridge have worked together to set up the free public access WiFi, which builds upon existing University networks to bring lasting benefits for the city and beyond.
It is the first step in making WiFi technology more widely available as part of Connecting Cambridgeshire's programme to improve connectivity across the county.
More than 20 new WiFi access points have been installed on lighting posts, CCTV poles and public buildings at key locations, including Parker's Piece, King's Parade, the Senate House and the market area. They include traditional looking lamp posts that have been specially engineered to host the latest WiFi technology discretely.
Councillor Steve Count, leader of Cambridgeshire County Council, which leads the Connecting Cambridgeshire programme, said: "This new free public WiFi service in central Cambridge is a fantastic example of the difference we can make for residents, visitors and students by working together.
"Developing wider public access WiFi and improving mobile coverage is part of Connecting Cambridgeshire's drive for better connectivity across the county, which is vital in an increasingly digital world. This trial paves the way for improving wireless connectivity across the city and beyond."
Jon Holgate, head of network at University of Cambridge, said: "The University of Cambridge has taken this opportunity to invest in free public WiFi because of the value of extending our existing University networks and bringing a lasting legacy for the city, which everyone can benefit from."
