London's iconic black cabs are set to be the next WiFi hotspots as a free access service will be revolved out early next year, In the latest expansion of internet access on the capital's transport network. Eyetease, a start up based in TechCity, the government-backed technology bunch in Shoreditch, said Transport for London had permitted its plan for advertising-funded WiFi in black cabs. The service will provide passengers free internet access in exchange for watching a 15-second advert every 15 minutes. The hotspots will connect to the internet via 3G or 4G depending on cover. Eyetease hopes the service will especially appeal to tourists seeking to avoid heavy roaming charges on to go online using their smartphone’s own 3G or 4G connection. That means that black cabs will join London Underground and Overground stations in offering free WiFi access. Swathes of central London are also covered now by providers including Nokia and O2. published by "The Telegraph"
