Wireless networks can be built in several topologies, and choosing the right one affects everything from coverage to scalability. In this episode, we compare ad hoc and infrastructure mode, explain what an SSID is and how it’s broadcasted, and examine the use of multiple SSIDs in multi-tenant or enterprise environments. You'll also learn about wireless isolation, SSID hiding, and service set types like BSS, ESS, and IBSS.

We then turn to antennas—omnidirectional vs. directional, gain measurements, and how antenna choice influences coverage patterns. Properly deploying antennas can make the difference between seamless coverage and constant dropouts. This episode ties together logical network design with physical signal deployment to help you create stable, predictable wireless environments.
