What does a basic service set (BSS) consist of?

• A. A single wireless client with no access point.
• B. One access point and one or more wireless clients.
• C. Multiple APs connected to a central controller only.
• D. Several APs and multiple wired devices.

Answer: (B)

A basic service set is the smallest building block of a Wi‑Fi network in infrastructure mode, consisting of one access point and all the wireless stations that are associated with that AP. The AP acts as the hub for wireless communication, coordinating access to the medium for its connected clients and defining the coverage area known as the Basic Service Area. Therefore, the scenario described fits best as one access point serving one or more wireless clients. If there were no AP, you’d be dealing with an ad hoc (IBSS) layout, which is a different form of BSS, and if multiple APs are present, each AP with its own clients forms its own BSS and the collection of those BSSs can be part of a larger Extended Service Set.
