Wi-Fi System Engineering

This course seeks to provide a concise overview of the architecture and operation of a typical Wi-Fi network. This includes an analysis of the Wi-Fi frame structure, as well detailing the access techniques Wi-Fi devices use to find and utilize a Wi-Fi network. The course also includes focus on two key areas that must be considered; Wi-Fi security and Wi-Fi QoS.
