ASU researchers debut ViWi-BT, an AI/computer vision mmWave beam guide

The cellular industry’s shift from long-distance radio signals to short-distance millimeter waves is one of the 5G era’s biggest changes, expected to continue with submillimeter waves over the next decade. To more precisely direct millimeter wave and future terahertz-frequency signals toward user devices, Arizona State University researchers have developed ViWi-BT, a vision-wireless framework that improves beam […]

The definitive guide to 5G low, mid, and high band speeds

Heading into 2019, 5G performance was largely theoretical: Standards-compliant 5G networks and smartphones were still nascent if not months away, so carriers focused more on building and testing their networks than guaranteeing performance. But over the past year, carriers across the world have rolled out multiple 5G networks and devices, using a combination of lab tests […]
