The Internet of Things (IoT) is living up to the hype. There are more than 20 billion end devices already networked through the Internet, with this number increasing more than three times by the year. In the process, end devices are becoming increasingly more intelligent and efficient, fueled by progress being made in artificial intelligence (AI), machine learning and even 5G, the new mobile phone technology, which creates the required bandwidths for data transfer in the IoT.
