Wireless networks are built on radio frequencies, and how you manage those frequencies has a massive impact on performance and reliability. This episode covers the 2.4 GHz and 5 GHz frequency bands, channel availability, and how channel overlap can cause interference and performance degradation. We explain how to choose non-overlapping channels in dense environments and how tools like Wi-Fi analyzers help you visualize spectrum usage.

We also cover channel bonding, bandwidth allocation, and how DFS (Dynamic Frequency Selection) works in the 5 GHz range. These topics are essential for deploying wireless networks that avoid contention, reduce retransmissions, and maximize throughput. Whether you’re tuning an enterprise network or helping users with laggy connections, this episode gives you the tools to optimize your wireless spectrum.
