This is a streaming video recording of the live version of this course that took place on 9 August 2019. Available for a limited time, this recording can help you prepare for the Wi-Fi Security course and give you an overall introduction to Wi-Fi technology. You can view the streaming video recording of this course as many times as you would like through 14 October. Register early to maximize your access to this limited time offer.
Wi-Fi systems are the most widely deployed wireless technologies in the world today. Yet, they receive less attention these days than cellular technologies like LTE. Despite the fact that Wi-Fi systems carry higher volumes of mobile data, operate at higher data rates than LTE, they are almost like commodity items that people don't think too much about but rather, take for granted.
However, Wi-Fi systems are actually 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! The latest high-rate Wi-Fi technology, 802.11ax (also known as High Efficiency Wireless) will come out later this year. Following in the traditions of 802.11n and 802.11ac, and extending them to even higher data rates, pre-standard 802.11ax products are already emerging in the market. Join us for a sneak preview of the highlights of 802.11ax.
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.
