Mobile World Congress 2015 brought together 2,000 exhibitors and tens of thousands of delegates under one roof in Barcelona. But as well as the myriad cell phone launches that are the show's trademark.
Tthis year's event also pointed to a brave new world of mobile technology, featuring speakers and exhibitors that had everyone asking questions from: What if cars could talk to each other? When will we outgrow 4G? And why isn't my vending machine smart yet?
So here are five forward-thinking pieces of tech that could shape our tomorrows, as showcased at Mobile World Congress.
Cars are no longer simply vehicles -- they are fast becoming high-speed internet hotspots. Audi and GM already have 4G LTE capability in some of their vehicles, but it's a technology that is becoming increasingly mainstream. AT&T and Audi announced at MWC that they planned to work together to have 4G LTE in every Audi 2016 model that is equipped with Audi Connect -- a navigation system, internet database and in-car wi-fi.
But what's the advantage of all that connectivity? Apparently, it means "better voice activation, better voice diagnostics -- all the things you want so your hands stay on the wheel and your eyes stay on the road," AT&T's chief executive Glenn Lurie told CNN's Richard Quest.
And ultimately, it means connected vehicles could communicate with other smart devices.
"It's about vehicles talking to vehicles and vehicles talking to infrastructure. It's about moving closer to self-driving vehicles," said Lurie. "It's about this working with your home, it's about inanimate objects taking care of you versus you taking care of them.
