The Internet of Things has always been more of an idea than an industry. The idea: connect everything. At its most simple, the concept of the Internet of Things is to put a sensor and a modem on everything and connect it to the cloud.
At its most complex, those things employ a sophisticated system of sensors, modems, processors, operating systems, cloud integration, apps, displays, voice platforms and machine learning. Think of the difference between a simple Bluetooth beacon and LG’s new InstaView smart refrigerator.
To categorize all of these things under the umbrella of “the Internet of Things” is absurd. It is true that most connected things share some common traits. The hardware and software are outgrowths of the mobile ecosystem, which was an evolution of the PC and Internet generation.
