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 com
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
