Question
Which of the following is not a type of frame defined in 802.11?
A. Connection frame
B. Management frame
C. Control frame
D. Data frame
Answer
A. Connection frame
Explanation
The option “A. Connection frame” is not a type of frame defined in the IEEE 802.11 standard for wireless LAN (WLAN) communication.
The IEEE 802.11 standard defines three main types of frames:
- Management frames: Used for wireless network management functions such as authentication, association, and deauthentication. Examples include Beacon frames, Probe Request/Response frames, and Association Request/Response frames.
- Control frames: Used for handshaking during the exchange of data frames. Examples include RTS (Request to Send), CTS (Clear to Send), and ACK (Acknowledgment) frames.
- Data frames: Used for carrying higher-layer protocol data from applications or services. These frames encapsulate the actual data payload being transmitted over the wireless network.
There is no separate category called “Connection frame” in the 802.11 frame types. The process of establishing a wireless connection between a station and an access point is typically handled through the exchange of specific management frames, such as Authentication and Association frames.
