Klappentext Technical insights on the vital aspects of hardware and software components in modern wireless system design Introduction to Wireless System Design: From Circuits to Web-based Applications provides an introductory level overview for readers to acquire technical insights on the most important aspects of modern wireless system design from an industrial and practical perspective. Various functional blocks of wireless systems and products are discussed and analyzed with practical examples of commercial products. Software development is addressed to provide a comprehensive understanding of the development of complete wireless systems. The book concludes by presenting practical design examples followed by future trends. Core topics covered in this book include wireless standards for GPS, Bluetooth, cellular, Wi-Fi, Zigbee, LoRaWAN, Sigfox, and NBIoT; major transmitter issues including power gain, power efficiency, harmonic prevention, and suppression; and server software development for building dynamic web interfaces using HTML, CSS, and JavaScript. Written by three highly qualified authors, the book also includes information on: System characteristics of hardware receivers, including noise temperature, bandwidth, figure, and sensitivity Components of circuit blocks in hardware transmitters, including oscillator, modulator, buffer amplifier, frequency multiplier, power amplifier, output filter Types of antennas, including dipole, monopole, loop, beam-forming, and miniature designs like patch, inverted-L, inverted-F, and meandered line Elements of software architecture design, including user interface, data and sequence flow, and timing diagrams Smartphone application software development, with insight on tools such as Android Studio, Flutter, React, and Swift Introduction to Wireless System Design: From Circuits to Web-based Applications is a highly practical and actionable resource on the subject for practicing engineers and programmers, as well as graduate and undergraduate students in related programs of study.
