The NCTI® Exploring Wireless Technologies course provides the student a comprehensive introduction to the underlying theory, design techniques and core principles of wireless communications. Whether the application is cell phones, Internet access or over-the-air television, the fundamentals of antennas and over-the air radio wave propagation remains the same. Many technicians work in these areas without learning about these fundamentals. Transmission lines are also discussed because antennas are connected to some form of physical medium, wire, cable, waveguide or circuit board. To address this immediate need, Exploring Wireless Technologies contains lessons from NCTI’s System and Advanced Technician courses that pertain to wireless communications.
