Boris Johnson has said that London will get a blanket wi-fi coverage by the time of the 2012 Olympics, with the internet available everywhere.
The London Mayor said his vision was that "every lamppost, every bus stop" in the capital would offer wireless internet access.
So far 22 London boroughs have signed up for the Project WiFi scheme, but no pricing plan has been announced.
The mayor was speaking at a Google event in Hertfordshire.
A similar scheme in the City of London already offers people internet access anywhere.
Mr Johnson also spoke about an upcoming app for Apple's iPhone, which will show locations of cycles for the London bike hire scheme.
"Not only can you see where the bikes are, but you will also be able to tell how many bikes the local yobbos have left there," he said.
The bike hire scheme, which involves cycle docking stations throughout the capital, is due to launch this summer.
