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. The 350 journalists in attendance weren't given an opportunity to try out the devices, but we did get a chance to see them. Curated demos showed off the network's capabilities.

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."
