The ability to communicate wirelessly is a vital feature found in telecommunications equipment, Internet of Things (IoT) gadgets, multimedia electronics, and automotive electronics. ZigBee, Bluetooth, Wi-Fi, RFID, IrDA, GSM, and CDMA are just a few examples of the technologies which we make use of in the course of our hardware design work across all of these many industries. This book presents an unusual point of view on communication techniques and challenges in embedded systems without delving into detail about all of the various factors that are crucial to the design of embedded systems, which is one of the book’s many strengths. Since embedded systems are increasingly communicating with one another on a massive scale, and because the fundamental component for embedded systems is made of telecommunications network infrastructure, it is relatively easy to provide a reason for selecting this choice. Embedded systems are capable of carrying out a wide variety of tasks, ranging from the straightforward exchange of digital material to the complicated coordination of the variety of complex joint operations carried out amongst collections of networked devices. Embedded systems can perform tasks as simple as the exchange of digital material and as complicated as the coordination of a variety of complex joint operations. This book studies the rising usage of embedded devices and electronic technologies from both a theoretical and practical standpoint. It also examines their applications in a range of domains, including agriculture, public health, the military, and the government. Since embedded systems are becoming more intricate, it is required to have some prior knowledge in a range of domains, such as electronics, data processing, telecommunications, and network design. This is because embedded systems are growing more complicated.
