Joel Crane is our special guest on CTS and he has a lot of knowledge bombs on spectrum analysis. Be sure to listen to this episode.

Interference. The invisible killer of your spectrum. It creates a terrible user experience and your network is to blame for it. Spectrum analysis is how you’re going to identify what is kicking your Wi-Fi to the side.

I’ve used this process to find issues the users are experiencing. Often times the fault is placed on the WLAN but it is either done unintentionally or on purpose. You will usually find out that there is a misbehaving device or a consumer level hardware causing issues with the WLAN.

In this episode, Rowell and François ask Joel Crane questions about what spectrum analysis is and why is it useful.
