What to expect from Mobile World Congress

The Mobile World Congress kicks off next week in Barcelona, Spain, where companies will be showcasing new devices and apps.

Samsung is expected to showcase its new Galaxy S7 phone in conjunction with the event after sales of its Galaxy S6 were considered lackluster.

And LG may show off a credit card replacement, the LG Pay card. The device is separate from the LG Pay mobile app, which already competes with Apple Pay and Alphabet's Android Pay, according to Adam Zuckerman, founder of tech networking site Fosterly.

Devices that fall under the broad category of the Internet of Things are also expected to be showcased.

Small firms including Braingaze, a so-called "mind tracking" technology company, and Natural Machines, a maker of 3-D food printers, will be considered for an Internet of Things award. And a number of executives at larger firms will be keynote speakers, including Facebook CEO Mark Zuckerberg and Ford Motor CEO Mark Fields, who is scheduled to discuss what Mobile World Congress calls "connected living."
