Which of the following standards supports MIMO technology?
A . 802.11a
B . 802.11b
C . 802.11g
D . 802.11n
Answer: D
Explanation:
The 802.11n wireless networking standard supports Multiple Input Multiple Output (MIMO) technology. MIMO technology uses multiple antennas on both the transmitting and receiving devices to improve wireless performance by increasing the amount of data that can be transmitted simultaneously. 802.11a, 802.11b, and 802.11g do not support MIMO technology.
