WLAN MAC Frames (graded) |
What MAC frames are used by wireless clients to discover a WLAN? Is disabling the broadcast of SSID (or network name) truly effective in hiding a WLAN from wardriving? What MAC frames are exchanged between a wireless client and access point when the client is joining a WLAN?
Contention Channel Access (graded) |
Explain why collision avoidance, instead of collision detection, is the philosophy of WLAN’s contention channel access method.
When multiple devices transmit on a WLAN, how do they contend with each other to use the network medium? Explain the role of backoff interval, frame acknowledgement (ACK), request to send (RTS)/clear to send (CTS), fragmentation, and interframe space (IFS) in reducing collision on WLANs.
