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.
