Mobile World Congress, Europe's biggest consumer electronics show with an expected 95,000 attendees, started this week. It's a show where the world's biggest electronics companies show off their latest devices that could make or break their year, NBC News reported.
Firms from Samsung to Huawei have scheduled events on Sunday, just before the official start of the conference on Monday and while much of the focus will be on the big players, themes from the future of 5G to driverless cars will be in focus.
A lot of the chatter at MWC will be around 5G, the next generation of mobile internet that will not only power our smartphones, but also the so-called "Internet of Things" (IOT). That includes your washing machine wanting to send you a message and anything else connected to the internet.
The number of IOT devices will number 38.5 billion in 2020, up for 13.4 billion in 2015, a 285 percent rise, according to Juniper Research. But the current network infrastructure will not be able to cope.
