In this section, you will build a strong foundation in wireless communication by understanding the essential concepts of radio frequency (RF) technology.

You will start by learning about radio signals, how they work, and why they are critical for wireless communication. Next, you will explore amplitude, power, and decibels (dB) to understand how signal strength is measured and managed.

We will then dive into real-world RF effects, such as attenuation, reflection, refraction, and multipath, which impact wireless networks. You will also learn how data is transmitted over RF signals, including modulation techniques.

We will cover interference, RSSI (Received Signal Strength Indicator), and SNR (Signal-to-Noise Ratio) to help you understand factors that affect wireless performance. Finally, we will focus on antennas, their characteristics, and the different types used in wireless networks.

By the end of this section, you will have a solid understanding of RF principles, which will prepare you for more advanced wireless networking concepts.
