Description
Radio frequency (RF) system design forms the basis of wireless communications. This course provides an overview of the principles of RF system design, including the use of antennas, propagation models, and interference mitigation. The course provides a classification of RF systems and then covers the basic functions of antennas, including the near and far fields, antenna gain, directivity, and radiation characteristics. Important RF propagation mechanisms are reviewed, such as the curvature of the RF beam and maximum RF range, surface (ground) wave, space wave, sky wave (ionospheric propagation), scatter propagation, and earth-space propagation. RF propagation impairments are described, including how multipath fading, interference, and noise will impact the threshold received power. Transmitter issues, crosslink Interference, and remote interference and management are also covered. The models governing free-space propagation, outdoor propagation models, and smoothness criteria are studied, together with link budget and receiving antenna electric field calculations. The course comprises 80 informative slides that are meticulously crafted to maximize clarity and accelerate learning.

Benny Bing has worked in academia for 30 years, and has published 20 books and over 70 scientific papers with 1,700 research citations. In 1999, tech giant Cisco Systems printed 18,000 copies of his pioneering book on Wi-Fi to launch its first wireless product. This groundbreaking move helped jumpstart 802.11b when there were only a handful of Wi-Fi vendors. He has also published an article for the IEEE Spectrum and was featured in the MIT Technology Review. He has taught custom training courses for many companies, universities, and the IEEE, including 8 industry-sponsored tutorials for the IEEE. His 6 U.S. patents were all licensed to industry and he has served as a residential broadband technology panelist for the National Science Foundation. He has received several industry, research, and teaching awards, such as the NAB Technology Innovation Award, the European Interactive TV Grand Challenge first prize, 2 IEEE best paper awards, and the Georgia Tech Center for the Enhancement of Teaching and Learning award. He is a certified computer-aided instructor, and has trained thousands of engineers globally, including China, Taiwan, Korea, India, Malaysia, Germany, Spain, Portugal, Chicago, Colorado, Atlanta, San Diego, and San Francisco. The instructor has also helped thousands of young adults get into STEM majors by offering standardized test prep courses.
The reason why his courses are popular is because the slides are meticulously prepared and insightful. They distill complex concepts into clean presentations and clearly summarizes the key points with a liberal use of graphics. A single slide may take hours to prepare and record to make it concise and engaging without sacrificing clarity or accuracy. This level of dedication cuts through the clutter that obscures effective learning. While most of the courses are beneficial to practicing engineers and students, some of them are also very useful to busy C-level executives. Any motivated learner will acquire a lot of information from the courses.
The material in the courses is continually updated to reflect the latest developments. There is also a set of test questions that accompany each course and is available from the instructor on request. The questions have been class-tested and are carefully crafted. More importantly, they make the student think over the material and learn something new from doing them. This instructor does not pad his courses with false 5-star reviews as he believes that the ultimate success of any course hinges on the motivation of the learner, and how the course material is taught to accelerate learning and maximize learning outcomes.
