The marquee part of Verizon's field trial is the van, which represents a "5G mobile device." The van drove about 10 miles an hour around the parking lot of the Verizon building, demonstrating how it could pick up 5G signals sent from a nearby base station.
The receiver is angled slightly so a brick wall partially obstructs the signal. 5G signals run on very high frequency airwaves, which don't have much range and get distorted easily. Verizon and Samsung said they've been able to get through one wall, but a second or third remains a problem.
On top of the base station was the radio antenna, which can shoot off multiple 5G signals in different directions. It's a trick called beam forming, which helps get the airwaves around obstructions like metal.
The van is blacked out from the inside. The only thing you can see is the large flat-screen display showing the speed of the connection. It peaks at 3.77 gigabits a second, or 377 times faster than your average LTE connection.
