A Comprehensive Study
Wi-Fi data rates and spectral efficiencies have continued to improve over the past two decades. By adding multi-user and multi-link transmission to multi-antenna and multi-carrier capabilities, next-generation Wi-Fi will be able to connect to an unprecedented number of personal devices and “things”, expanding beyond user-to-user communications. This course describes the foundational principles of Wi-Fi, including state-of-the-art technologies and applications. In addition to 11n, 11ac, and 11ax, it discusses the latest technical details of the new 802.11be amendment and provides a comparative assessment of 802.11ax and 802.11be. The course also presents practical issues in Wi-Fi performance optimization, and key physical and access layer mechanisms. Among the topics covered include OFDM, OFDMA, multi-user multi-antenna multi-link technologies, beamforming protocols, and operating range versus rate tradeoffs. This indispensable course is designed for any wireless engineer building advanced Wi-Fi systems from ground up and comprises 200 informative slides that are meticulously crafted to maximize clarity and accelerate learning.

About the Instructor
The instructor has published 7 generations of Wi-Fi books. Cisco Systems adopted 18,000 printed copies of one of his books to launch its first wireless product―the Aironet Wi-Fi product. This bold move helped jumpstart Wi-Fi (802.11b) in 1999 when the first version of the standard (ratified in 1997) was a failure and the technology was facing intense competition from 3G cellular, riding on the global success of 2G. Additionally, the Wi-Fi Alliance rebranded itself from WECA and was at the crossroads with weak support from a handful of vendors. The instructor has conducted on-site Wi-Fi courses for universities and companies such as Qualcomm and Motorola Solutions, and has served as an expert witness on Wi-Fi.
