Olivier Ropars, senior director of mobile commerce at eBay Europe, which compiled the report that suggests that the 4G mobile network could provide a boost to the UK economy, said:
Consumers today want convenience and speed.
The arrival of universal 4G will bring with it a more immersive, instant and intimate shopping experience than ever before - putting the most exciting features of mobile retail as we know it into high definition.
It won't just turbo-charge the way we shop. It will truly give us the ability to shop anytime, anywhere.
That means an extra £1.8 billion of consumer spending up for grabs.
