CWNA-106 · Question #30
In an 802.11n 2.4 GHz BSS, what prevents each station from using the full network bandwidth (e.g. 130 Mbps) for user data throughput when multiple clients are actively exchanging data with the AP?…
The correct answer is C. The DCF and EDCA coordination functions require backoff algorithms D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment. See the full explanation below for the reasoning.
