Course Overview
The NCTI Exploring Wireless Technologies course provides a comprehensive introduction to the invisible physics that power our modern world. Whether working with Cell Phones, Wi-Fi, or Over-the-Air (OTA) Television, the fundamental laws of Radio Frequency (RF) remain the same.
Many technicians install equipment without truly understanding the science behind it. This course bridges that gap, offering a deep dive into Radio Wave Propagation, Antenna Theory, and Transmission Lines. By mastering these core principles, students will be equipped to troubleshoot and optimize any wireless system—from terrestrial microwave links to complex satellite communications.
Who Should Attend:
- Wireless Technicians (Cellular/Wi-Fi)
- RF Engineers
- Headend Technicians
- Satellite Installers
What You Will Learn
Upon completion, students will be able to visualize how signals travel through the atmosphere and how hardware is designed to capture them efficiently.
Core Competencies:
- Modulation Mastery: Differentiate between unmodulated carriers, Amplitude Modulation (AM), Frequency Modulation (FM), and Digital variations.
- Circuit Logic: Identify functional receiver blocks, tuned circuits, and Intermediate Frequencies (IF).
- Transmission Lines: Define characteristic impedance and techniques for adjusting transmission lines to match loads (VSWR).
- RF Propagation: Explain how electromagnetic waves travel through the atmosphere, including ground waves, sky waves, and line-of-sight.
- Antenna Principles: Categorize antenna types (Dipole, Yagi, Dish), understand gain/directivity, and optimize performance for specific applications.
- Microwave & Satellite: Describe the operation of microwave waveguides, diodes, and ground-based satellite antenna systems.
