Those infuriating moments spent on the pavement waiting for your smartphone to download a street map, pixel by pixel, may soon be over, as technology companies push towards a future of free public wireless internet for all.
Virgin Media has announced plans to create a free wi-fi network to cover all of London, to compete with the often unreliable 3G mobile phone network and a patchwork of other wi-fi services.
In a speech to investors, Virgin Media's chief executive, Neil Berkett, said it planned to provide the service "in the not too distant future".
Virgin Media was in "quite advanced negotiations" with London councils over permission to install wireless routers across the city, he added.
The capital, like many other UK cities, is already served by BT Openzone, one of the largest wi-fi networks. However, BT charges for access to non-BT customers.
