Welcome to the start of a new journey, where you will develop an understanding of what it takes to create and maintain an effective and secure WLAN in today's environment. As the size of wireless networks increases, so does the complexity of the network design that relates to their deployment. Therefore, understanding Wi-Fi principles is essential in efficiently installing and troubleshooting Wi-Fi networks. To create and maintain an effective and secure WLAN, you must understand the various wireless components and topologies you will encounter. Foundational–level knowledge including RF principles and mathematics, including antenna characteristics will be covered in this course.

One of the most important aspects of wireless operation is how Wi-Fi operates over the air. One of the main problems for the creators of Wi-Fi protocols, was eliminating the interference that other devices cause, and mitigating the impact of this interference on the signal. To meet this need, spread spectrum transmission technology was used. This course examines the basics of spread spectrum technologies, Wi-Fi 6E, media access, and wireless governance.
