Which of the following wireless standards provide speeds up to 150Mbps?
A. 802.11a
B. 802.11b
C. 802.11g
D. 802.11n
Answer: D
Explanation:
802.11n builds upon previous 802.11 standards by adding multiple-input multiple-output (MIMO). The additional transmitter and receiver antennas allow for increased data throughput through spatial multiplexing and increased range by exploiting the spatial diversity through coding schemes like Alamouti coding. The speed is 150 Mbit/s (even 250 Mbit/s in PHY level)
