Our team —and 100,000 fellow visitors— are slowly returning to reality after a crazy week spent at the world's largest mobile-themed "amusement park" that is Mobile World Congress. And even if MWC still resembles a tech Disneyland, this year, it was not only about taking the latest Virtual Reality devices for a spin.

Besides entertaining the masses, companies started to focus on how to create useful, profitable use cases around emerging tech such as AI or Augmented Reality, to make people's lives better and drive business.

It's hard to believe that it's been almost a year since we last wrote up our thoughts on Mobile World Congress. In the 2015 edition, IoT and wearables received quite a lot of attention. On the other hand, enthusiasm for VR/AR glasses seemed somewhat modest. This year, the sleeping giant woke up.

BARCELONA - The Mobile World Congress in Barcelona now attracts over 93,000 visitors and owing to the sheer size of the show it becomes a real challenge to see even half of what is offered.
