In Lecture 4, we reviewed the performance constraints of wireless systems, focusing on two primary issues: channel impairments caused by fading and interference arising from concurrent users accessing the same channels. These factors significantly impact the quality and reliability of wireless communication. A crucial metric for evaluating wireless link quality is the Signal-to-Noise Ratio (SNR), which helps in understanding the robustness of communication under real-world conditions. This lecture emphasizes the importance of addressing these challenges for improved wireless network performance.
