Europe’s largest free WiFi zone is to be rolled out across large parts of London city in time for this summer's Olympic and Paralympics Games.

Mobile operator O2 is to provide the service, which will aim to cover the boroughs of Westminster, Kensington and Chelsea by March.

The network will be powered by devices that will be attached to existing street furniture, including lampposts.

It will be accessible to the areas' estimated 250,000 residents as well as all those expected to travel to the city for the Olympic Games, which will begin in late July.

Cities like Paris have already rolled out large, free WiFi networks however most only offer connectivity in limited areas like parks and train stations.

So far no Irish cities have rolled out free WiFi networks, though individual businesses often offer such services to their customers.
