Study Notes

WLAN Architecture

The most common WLAN architecture is Infrastructure Wireless LAN Architecture.

Communication between Client Stations

In Infrastructure Wireless LAN Architecture, client stations do not communicate directly with each other; instead, they communicate through an Access Point (AP).

BSSID (Basic Service Set Identifier)

The BSSID is a 48-bit identifier that uniquely identifies a Basic Service Set (BSS) in an Infrastructure Wireless LAN Architecture.
The BSSID is typically the MAC address of the Access Point (AP).

Site Survey

Infrastructure Wireless LAN Architecture usually requires a site survey to determine the optimal placement of Access Points (APs) and to ensure adequate coverage and minimize interference.

Comparison with Ad Hoc Network (IBSS)

The main disadvantage of Infrastructure Wireless LAN Architecture compared to IBSS (Ad Hoc network) is the need for an Access Point (AP), which introduces a single point of failure.
The main advantage of Infrastructure Wireless LAN Architecture is the ease of management and scalability.

Client Station Communication

If 802.11 client stations wish to communicate directly with each other in Infrastructure Wireless LAN Architecture, they must do so through the Access Point (AP).
