Over the past few years, the Internet of Things (IoT) has generated a lot of hype, touting how embedded sensors combined with mobile technologies will lead to a multitude of connected devices and services (all generating a deluge of data), which will open up a gold rush of opportunities in the consumer, business, technology, and industrial worlds. We've also learned that the IoT is not just about sensors and a lot of data and analytics; it also involves the application of new technologies including drones, wearable computers, and smart networks, as well as new practices such as predictive maintenance.
