If you’re new to WiFi or used to deploying access points for large enterprises, the word “controller-less” might be confusing. Traditionally to manage access points across a business, a separate piece of hardware referred to as a “controller” would be installed along with the access points and router. This controller typically would live in the server room and monitor, analyze, and update the access points across the deployment. In some cases the hardware controller would provide firewall features for added protection as well. At the time, when wireless technology was still relatively new this was a convenient way to manage all access points in a streamlined manner.

Internet used to be a measly dial up connection that only a handful of families had access to at home. Now dial up is no longer in existence, and just about any device you can think of comes WiFi enabled from refrigerators to door locks. We use more WiFi than ever before and expect to have it while grocery shopping, while at work, and even on airplane trips.
