The Role of IoT and Narrow Band (NB)-IoT for Several Use Cases

Internet of things (IoT) and its improved version narrow band Internet of things (NB-IoT) use smart networks to meet the needs of the modern world. These components are very important for collecting data from the environment and correctly managing the related scenarios, and thus more use of wireless networks in IoT-supported heterogeneous networks. Decision making is the main component in the IoT universe, and this function’s consistency depends on the accuracy of the data obtained from the sensor nodes. IoT and NB-IoT are the most exciting cutting-edge technologies for solving above-mentioned problems. IoT supports many revolutionary commercial and social solutions, including food production, wearable or inconspicuous medical sensors, Industry 4.0, power, water grids, smart cities, education, transportation and road infrastructure needs. Industry 4.0 symbolizes the beginning of the Fourth Industrial Revolution. Industry 4.0 represents the current trend of automation technologies in the manufacturing industry and primarily covers cyber-physical systems (CPS), IoT and cloud computing at the moment, low power wide area network (LPWAN) is a promissory and highly effective solution for IoT and machine-to-machine (M2M) communication-based applications with long range and low power consumption. With the eagerly awaited developments in artificial intelligence, machine learning, data analysis, and block chain technologies, LPWAN applications have the potential to undergo epic expansion in nearly every area of society, business, and industry. This chapter aims to stimulate a discussion about the role of IoT and NB-IoT which can play in overcoming the limitations of a wide-ranging deployment of autonomous networks and their usage in real-world phenomena.
