What is a difference between an Infrastructure Basic Service Set (BSS) network and an Ad...

In an Ad Hoc network, only one WLAN controller is used. A BSS allows multiple WLAN controllers to be connected together to form a mobility domain.

An Ad Hoc network allows only legacy security options such as WEP. A BSS allows the creation of a robust security network (RSN) using security methods such as WPA2-Personal.

A BSS is recommended for enterprise WLANs, while Ad Hoc deployments are recommended for small and medium businesses.

In a BSS, an access point is used for connectivity to the wired network infrastructure. In an Ad Hoc network, client stations communicate directly with each other.
