Preface

Drawing on over 60 years of combined, award‐winning experience at the forefront of electronics and information technology, we bridge the critical gap between hardware and software. In today's competitive landscape, true innovation in wireless communication happens at the intersection of these two domains, and expertise in only one of them is no longer sufficient. This book offers a practical, hands‐on guide that provides a clear framework for this integration, written for engineers, programmers, and managers. We guide you through the entire technology stack—from the foundational hardware of electronic circuits and devices to the architecture of complex systems, and from low‐level embedded software to sophisticated server platforms and mobile applications. With an emphasis on practical applications over dense theory, this book is rich with real‐world design examples and insightful discussions, providing the comprehensive, cross‐disciplinary knowledge required to develop superior products. It is designed to equip you with the understanding needed to build the robust, efficient, and innovative wireless solutions of the future. For those wishing to explore specific topics in greater detail, each chapter provides curated bibliographic references for further study.

This book is organized into 4 sections and 12 chapters, covering Wireless Standards, Hardware Design, Software Design, and Putting into Practice.

The opening section, Wireless Standards, consists of Chapter 1, which introduces the fundamentals of wireless technology in the Internet of Things (IoT). The chapter provides an overview of network topologies, major wireless standards, and the regulatory landscape of compliance and certification. Understanding these core concepts is essential for appreciating the role of performance and reliability in developing compliant IoT systems.

The Hardware Design section begins with Chapter 2, which focuses on receiver design in communication systems, emphasizing circuit blocks and system architectures. It examines essential circuit components and discusses various system architectures and design considerations, such as heterodyne, direct conversion, and image‐reject receivers. This chapter offers a thorough understanding of receiver design, laying the groundwork for addressing the demands of modern wireless systems.

As a complement to receiver design, Chapter 3 focuses on transmitter design, considering the system as a whole and its performance factors. It explores critical building blocks like the oscillator, modulation techniques, and upconverters. Power amplification, output filtering, and other considerations are also examined. Different transmitter architectures, including direct conversion and heterodyne, are discussed. The concept of transceiver architectures is introduced, along with various configurations. This provides readers with a comprehensive understanding of transmitter system design, serving as a foundation for advanced concepts and techniques in future designs.

Chapter 4 provides an overview of a new radio, the software‐defined radio (SDR) and its advantages over conventional radio systems. SDR relies on digital signal processing algorithms, reducing the need for analog hardware and improving reliability and spectrum utilization. The underlying concepts and architecture of SDR are explored, including key building blocks such as antennas, radio frequency (RF) front ends, and analog‐to‐digital and digital‐to‐analog converters. The role of software‐defined antennas and the importance of the RF front end in signal transmission and reception are discussed. Signal processing functions in SDR systems, including modulation, demodulation, and error correction coding, are examined.

As one of the key elements in wireless systems, Chapter 5 focuses on antennas for handheld wireless devices, highlighting their crucial role in ensuring efficient and reliable communication. It explores the fundamentals of antenna radiation, parameters affecting performance, and different types of antennas commonly used in handheld devices. Additionally, practical design considerations for overcoming size constraints in portable devices are addressed. The chapter provides valuable insights for optimizing antenna performance in handheld wireless devices.

Chapter 6 provides an overview of printed circuit board (PCB) design for wireless devices, emphasizing their role in performance and functionality. It discusses key RF PCB design considerations such as layer stack‐up, component placement, grounding, power plane design, and decoupling strategies. The chapter addresses challenges like high‐frequency signals, signal integrity, power distribution, and interference mitigation, highlighting the importance of proper grounding and noise reduction techniques. It also covers design strategies for various circuit types, including intermediate frequency, RF, baseband, audio, and power supply circuits. Overall, the chapter equips engineers with the essential knowledge needed for creating high‐performance PCB layouts.

As an opening chapter of Software Design section, Chapter 7 highlights the vital role of embedded software design in modern electronic devices, covering applications from consumer products to industrial systems. It defines embedded systems as specialized platforms optimized for specific tasks with constraints on processing power, memory, and energy.
