Good news if you plan on calling a cab in London and Birmingham and need some superfast data connectivity - EE is bringing 4G cabs to those cities.The 4GEE Taxis, described as the UK’s first ever fleet of 4G enabled hackney carriages, are now on the road in those locations, noticeable by the bold corporate branding and out there to showcase the company's 4G service. Which is why the service is free as you ride.Each car (of the 50 in total) has been given a hi-tech makeover and fitted with a state-of-the-art MiFi wireless router that acts as a mobile 4G hotspot connecting the cabs to the 4G network.Spencer McHugh, Director of Brand, EE said: 'The first motorised black cabs hit the streets in 1901, nearly 70 years before the first smartphone was available to consumers, now we are bringing this icon of British transport into the 21st century with a 4G make-over. We hope this trial will demonstrate the benefits of a superior online experience as users can browse, download, catch up on emails, Tweet and check Facebook literally at the speed of light. We can’t make taxi journeys any faster but we can certainly speed up people’s smartphones!'The free 4G service will be available for three months with 40 traditional Hackney carriages in London and 10 in Birmingham compatible with 4G.
