Course Description

The excitement over Wi-Fi 6 (also known as 802.11ax or High Efficiency Wireless) has been growing over the past couple of years. Significant changes have been incorporated into 802.11ax that promise better throughput in dense deployment scenarios. In this course, we journey through the development of Wi-Fi from the earlier generations of the system all the way to Wi-Fi 6.

Wi-Fi systems are very sophisticated systems that were created to satisfy difficult and challenging requirements. For example, they operate in unlicensed bands, with very severe emission limits; also, they need to provide high data rates because they are in direct "competition" with wired LANs using technologies like Ethernet with super-fast rates; furthermore, in some scenarios, Wi-Fi systems are deployed in a somewhat distributed manner, without strong centralized control. Thus, challenges of interference management and resource sharing arise. Additionally, different types of traffic might need to be given different treatment (QoS), resulting in additional challenges from the resource sharing and interference management perspectives. These other technical challenges have been handled over the years (as different members of the Wi-Fi family of technologies have been created) through a variety of solutions and approaches, some of which are pretty ingenious from an engineering point of view.

We will explore these along with the solutions and approaches. Examples of such creative solutions include the various coordination functions at the MAC layer (e.g., DCF, PCF, etc.) spread spectrum, OFDM, etc., to handle challenging constraints at the physical layer while trying to achieve high data rates.

NEW - Just added this year! Wi-Fi 6 is rekindling interest and fascination in 802.11 based wireless LANs. Following in the traditions of 802.11n and 802.11ac, and extending them to even higher data rates, pre-standard 802.11ax products are emerging in the market. Join us for a tour of the highlights of Wi-Fi 6.

Who Should Attend

Wireless and telecom engineers, researchers, and students will find value. Prerequisites: typical first two years of a college electrical engineering course, an introduction to communications systems, or equivalent knowledge from work experience in wireless / telecom engineering.

Take this course to:

• Gain a systems perspective of a complex set of technologies put together into practical systems to meet real-world requirements for certain high-demand applications
• Deepen your understanding and appreciation for the design choices and tradeoffs of Wi-Fi systems via numerous comparisons with other wireless systems

Learning Objectives

• Understand Wi-Fi systems from a systems perspective - learn how the different components are put together and work together
• Learn how to design Wi-Fi deployments to optimize usage of Wi-Fi technologies
• Explain the pros and cons, and the tradeoffs involved, of using various members of the Wi-Fi family of systems, for various applications
• Explore ideas for solving problems posed by requirements for new communications systems (with Wi-Fi and its requirements as an example)
• Compare and contrast wireless technologies more accurately and with deeper insight and understanding than before
