MAUI—Coinciding with Qualcomm’s annual Snapdragon Summit in Hawaii, Verizon deployed a mmWave 5G network on-site at the Grand Wailea that has been consistently pushing download speeds north of 3 Gbps and upload speeds in the 200 Mbps to 300 Mbps range. While the crowd at the event is largely using that network to rack up quadruple-digit speed test figures, Brian Meacum, Verizon’s vice president of device technology, said the point was to highlight the performance of mmWave 5G—“It’s pretty ridiculous what you can do,” he told me as we ran speed tests on a fifth-floor lanai overlooking the Pacific.
