The NCTI® Applying Wi-Fi Technologies course teaches the broadband technician about the application of elements and principles that support installation and troubleshooting of Wi-Fi within the home, as well as in business environments. Wave propagation, channel assignment, interference, security and frequency bands, are just some of the fundamental topics technicians working in the Wi-Fi environment must understand. While Wi-Fi signals have become commonplace, there remains the need to understand the various ways 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 as well as advanced topics.

Completion Time:

The estimated seat time for this course is 10 hours. The maximum allotted time is four months from enrollment.

Benefits:

  • receive an industry-recognized NCTI certificate of graduation
  • receive credit toward NCTI Telecom Specialist certification
  • receive credit toward NCTI Master Installer certification
