While the 5G data connection news doesn't sound very exciting on its own, it's a sign that Qualcomm's technology is closer to something that consumers can actually use. It's also developed a tiny millimeter wave antenna module (above), which is the size of a nickel -- significantly smaller than competing designs. The company claimed the X50 could see speeds up to 5Gbps last year, but those speeds are far from what we'll initially see with 5G deployments. Gigabit is more feasible to begin with, especially since that's just the next step beyond what we're seeing with gigabit LTE (which actually get between 100 Mbps and 300 Mbps speeds in real world performance).
According to Qualcomm reps, the 5G specification could be completed much sooner than we think. The first version will likely be finished by this December, and the company expects 5G phones to reach consumers in the first half of 2019. That's a full year later than Qualcomm was expecting last October, but it seems much more realistic.
As for its 5G reference device, it's the first proof we've seen that the X50 chip can fit inside a smartphone. Don't judge its looks too harshly, though. Reference designs aren't usually very pretty -- they're more of a testbed for how other companies can deploy Qualcomm's technology.
