Samsung’s Galaxy S9 and Nokia’s Banana Phone Steal the Big Mobile Show

The future of phones is on display at Barcelona's 2018 wireless extravaganza.

Some 100,000 people are descending on Barcelona for the 2018 Mobile World Congress to see the latest smartphones, AI devices and autonomous drones exhibited by more than 2,000 companies. The wireless industry’s biggest conference is also the industry’s largest networking opportunity for executives, bankers, analysts and the like to talk shop — and potential deals.

Among the CEOs are Deutsche Telekom AG’s Tim Hoettges and Vodafone Group Plc’s Vittorio Colao, who will jostle for airtime discussing the major trends shaping the industry such as cybersecurity, the arrival of ultrafast fifth-generation mobile networks and blockchain.
