Internet of things Software Defined Networking (SDN) provides the agile dynamic solution that can cope with the special requirements of the diversity of innovative IoT applications. The Internet of things would encode 50 to 100 trillion objects, and be able to follow the movement of those objects. Human beings in surveyed urban environments are each surrounded by 1000 to 5000 trackable objects. In 2015 there were already 83 million smart devices in people's homes. This number is about to grow up to 193 million devices in 2020 and will for sure go on growing in the near future. The figure of online capable
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.
