Which of the following are improvements of the 802.11n standard versus the 802.11a and 802.11g standards? (Choose all that apply.)
A)operates at up to 54 Mbps
B)uses MIMO
C)utilizes WEP for security
D)uses aggregation of frames and ACK responses

Question

Quizplus · Accepted Answer

802.11n improves upon the previous standards by utilizing MIMO (multiple-input multiple-output) technology which allows for multiple streams of data to be transmitted simultaneously, increasing data transfer rates. It also uses frame aggregation and ACK (acknowledgment) responses to reduce overhead and improve overall throughput. Option A is incorrect as 802.11n can operate at speeds up to 600 Mbps, while 802.11a and 802.11g are only capable of up to 54 Mbps. Option C is incorrect as WEP is an outdated and insecure form of wireless encryption that is no longer used in modern networks.
