"There is a growing need for books and preparatory materials that can help wireless engineers prepare for the IEEE WCET (Wireless Communications Engineering Technologies) certification exam. This book offers a broad exposure to the wireless communications field as it is practiced in the real world, providing the necessary practical, hands-on knowledge. The author, who was involved with the certification program development, shares in-depth knowledge and insight on the WCET exam. Readers planning to take the exam, engineers seeking to increase their knowledge of WCET, and graduate students and professors in wireless communications will find this guide invaluable"--

Intended for electrical engineering students and readers studying for professional examinations such as the WCET certification, this volume on wireless communications technologies provides a comprehensive overview of the hardware, software, standards and regulations involved in the rapidly expanding world of wireless and mobile communications. Beginning with reviews of basic circuitry and components, the work covers radio frequency, antennas, and propagation, wireless access technologies, network and service architectures and advanced topics in wireless engineering. Chapters include illustrations, equations, schematics, and exercises, and a series of appendices provide additional information for exam candidates. Wong is a former professor at the Malaysia University of Science and Technology and a wireless networking consultant. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com)

A broad introduction to the fundamentals of wireless communication engineering technologies

Covering both theory and practical topics, Fundamentals of Wireless Communication Engineering Technologies offers a sound survey of the major industry-relevant aspects of wireless communication engineering technologies. Divided into four main sections, the book examines RF, antennas, and propagation; wireless access technologies; network and service architectures; and other topics, such as network management and security, policies and regulations, and facilities infrastructure. Helpful cross-references are placed throughout the text, offering additional information where needed.

The book provides:

  • Coverage that is closely aligned to the IEEE's Wireless Communication Engineering Technologies (WCET) certification program syllabus, reflecting

  • the author's direct involvement in the development of the program

  • A special emphasis on wireless cellular and wireless LAN systems

  • An excellent foundation for expanding existing knowledge in the wireless field by covering industry-relevant aspects of wireless communication

  • Information on how common theories are applied in real-world wireless systems

With a holistic and well-organized overview of wireless communications, Fundamentals of Wireless Communication Engineering Technologies is an invaluable resource for anyone interested in taking the WCET exam, as well as practicing engineers, professors, and students seeking to increase their knowledge of wireless communication engineering technologies.
