Course Overview
The NCTI Applying Wi-Fi Technologies course is designed for broadband technicians responsible for installing, optimizing, and troubleshooting wireless networks in both residential and commercial environments.
While Wi-Fi signals are commonplace, delivering a flawless wireless experience requires deep technical knowledge. This course moves beyond basic connectivity, teaching technicians how to manipulate wave propagation, manage channel assignments, and mitigate interference. Students will master modern standards—including the 6 GHz frequency band—and learn to deploy advanced solutions like Mesh networks and Managed Wi-Fi to eliminate dead spots and ensure security.
Who Should Attend:
- Broadband Installers
- Wi-Fi Support Technicians
- Network Field Engineers
What You Will Learn
Upon completion, students will be able to design and troubleshoot robust wireless networks using industry-standard tools and protocols.
Core Competencies:
- Spectrum & Standards: Master IEEE 802.11 amendments and frequency characteristics across 2.4, 5, and the new 6 GHz bands.
- Advanced Hardware: Explain the function of MIMO, MU-MIMO, and Beamforming for signal enhancement.
- Modern Security: Implement robust security using WPA3 and SAE, and understand the deployment of RADIUS servers for enterprise environments.
- Network Optimization: Compare Mesh Networking to traditional setups, optimize device placement, and utilize “Managed Wi-Fi” benefits.
- Diagnostic Tools: Utilize Wi-Fi scanners and Spectrum Analyzers to interpret waterfall views, detect non-Wi-Fi interference, and visualize RF density.
- Commercial vs. Residential: Distinguish between home setups and commercial requirements, including PoE networks and centralized Access Point (AP) management.
