Qualcomm President Cristiano Amon on Tuesday showed off a 5G prototype device that can access "live" 5G networks running at the Grand Wailea Hotel, the location of conference. It's powered by Verizon and AT&T. CNET is on the ground at the event and will bring you more details about what it's like to actually use 5G in a mobile device.

5G "will lay the foundation for smartphones, later cars and virtually every electronic device that will be connected," Amon said during a keynote. "That first step (smartphones) is getting to us in the first half of 2019."
