Episode 174: Wireless Limitations — Throughput, Signal Strength, and Power

Wireless technology is incredibly convenient—but also limited by physical and environmental factors. In this episode, we explore the inherent constraints of wireless communication, such as reduced throughput compared to wired networks, signal degradation over distance, and interference from walls, other devices, or even weather. You’ll learn how to interpret RSSI (Received Signal Strength Indicator), SNR (Signal-to-Noise Ratio), and transmit power levels.

We also discuss how device type, antenna gain, and client location affect performance. These limitations require careful AP placement and network tuning to ensure optimal coverage and speed. This episode helps you set realistic expectations for wireless performance and diagnose poor user experiences caused by physical-layer factors.
