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).
