Wi-Fi System Engineering Training

As service providers try to deal with our unquenchable thirst for Internet connectivity, the role of Wi-Fi has grown from a simple wireless LAN technology to a critical element of the communication mix. This course therefore focuses on the IEEE 802.11 family of technologies; 802.11n (Wi-Fi 4), 802.11ac (Wi-Fi 5) and 802.11ax (Wi-Fi 6) and in so doing, explains the architecture and operation of a Wi-Fi network.
