Mobile communications industry gathers in Barcelona for MWC 2015

Mobile World Congress will as usual not feature Apple - and nor will users be represented - but it remains the industry's biggest show in town

The world's largest mobile technology event kicks off on Sunday with more than 86,000 salespeople, software engineers, chip designers, device makers and television crews arriving in Barcelona for the five-day event.

With Facebook's Mark Zuckerberg headlining, alongside Google rising star Sundar Pichai and the omnipresent Will.i.am, who has moved from recording music into designing electronic wristbands, the Mobile World Congress will fill the halls of two separate exhibition centres and take over countless unofficial venues around the Catalan capital.
