History of IoT
The concept of connected devices, which forms the basis of IoT, has been around since the 1970s. However, the term "Internet of Things" was first mentioned by Kevin Ashton in 1999 during a presentation to Procter & Gamble. Ashton coined the term to incorporate the idea of connecting everyday objects to the internet. Neil Gershenfeld's book, "When Things Start to Think," published in the same year, further highlighted the vision of IoT.
The evolution of IoT can be traced back to the convergence of wireless technologies, microelectromechanical systems, microservices, and the internet. This convergence broke down the barriers between operational technology and information technology, allowing machine-generated data to be analyzed for valuable insights.
Although Ashton's mention of IoT was significant, the concept of connected devices had already been explored under different names such as "embedded internet" and "pervasive computing." The first internet appliance, a Coke machine at Carnegie Mellon University in the 1980s, allowed programmers to check stock availability remotely.
The evolution from machine-to-machine (M2M) communication to IoT took the concept further. M2M focused on connecting devices to the cloud for management and data collection. IoT expanded this concept to create a network of smart devices, connecting people, computer systems, and applications to collect and share data.
The Chinese government's inclusion of IoT as a strategic priority in its five-year plan in 2010 played a significant role in the growth and development of IoT. From 2010 to 2019, IoT gained increased consumer use and expanded into cellular IoT, operating on various networks such as 2G, 3G, 4G, 5G, LoRaWAN, and LTE-M. In 2023, billions of internet-connected devices are expected to collect and share data for consumer and industrial use.
IoT has also played a vital role in the emergence of digital twins, which are virtual representations of real-world entities or processes. IoT sensors enable the physical connection between entities and their digital twins, making a well-configured IoT implementation essential for digital twin technology.
Similarly, IoT has made significant contributions to healthcare through wearables and in-home sensors that remotely monitor patients' health. These devices allow healthcare providers to deliver personalized and continuous care, improving patient outcomes.
