5G promises dramatically faster speeds, lower latency and increased capacity than today's 4G LTE technology. It's also a potential alternative to WiFi with greater reliability and performance in industrial settings.
Coverage, standards, and device support still aren't where they need to be for full deployment, but that isn't stopping some companies. Early adopters are rolling out 5G initiatives before all the pieces are fully in place, in order to reap immediate benefits and get a jump on the competition.
