Applying Wi-Fi Technologies
Course Overview
The NCTI® Applying Wi-Fi Technologies course teaches the broadband technician about applying elements and principles that support installing and troubleshooting Wi-Fi within the home and in business environments. Wave propagation, channel assignment, interference, security, and frequency bands are fundamental topics that technicians working in the Wi-Fi environment must understand. While Wi-Fi signals have become commonplace, the need remains to understand how devices receive and process Wi-Fi data, troubleshoot interference, and optimize Wi-Fi within the home or business. The Applying Wi-Fi Technologies course is appropriate for all Wi-Fi installation and troubleshooting technicians working in a Wi-Fi environment, offering fundamental and advanced topics.

Identify wireless router components and antenna features, and explain how beamforming is used for signal enhancement.
Describe how SISO and MIMO devices communicate and the MU-MIMO advantages over MIMO and SISO.
Explain the difference between SSIDs, ESSIDs, and passphrases, why WEP should not be utilized, and clarify the differences between WPA, WPA2, and WPA3.
Explain the significance of SSIDs and Wi-Fi security types, the difference between Wi-Fi frequency bands, and the impact of transmit power and channel width choices.
Describe Wi-Fi scanner operation, limitations, network graph, and how spectrum analyzers detect RF activity, including density and waterfall views, navigation waterfall, utilization measurements, and signature identification.
