Internet of things diversified usage of Internet of things. Governmental regulation is argued by some to be necessary to secure IoT devices and the wider Internet – as market incentives to secure IoT devices is insufficient. IoT systems are typically controlled by event-driven smart apps that take as input either sensed data, user inputs, or other external triggers (from the Internet) and command one or more actuators towards providing different forms of automation. Examples of sensors include smoke detectors, motion sensors, and contact sensors. Examples of actuators include smart locks, smart power outlets, and door controls.

Smart Cell Smart Cell Smart Cells are innovative ubiquitous radio access nodes that provide wireless connectivity across multiple spectrum ranges and technologies. As of January 2014, Macrocells, Small Cells, and Wi-Fi connections were the primary means of data connectivity. For these types of cells, the spectrum utilized is static and is based on the antenna installed. "A Smart Cell may transmit multiple frequencies and technologies which are controlled by the software and not the hardware" (antenna). Smart Cells are currently in the research and development stage but support software-defined networks which are proliferating the current mobile network structure, led by AT&T's adoption.
