A network technician has been tasked with designing a WLAN for a small office. One of the
requirements of this design is that it is capable of supporting HD video streaming to multiple
devices. Which of the following would be the appropriate wireless technology for this design?
A.
802.11g
B.
802.11ac
C.
802.11b
D.
802.11a
Explanation:
802.11ac is the best answer. 802.11n would have also been acceptable.
802.11ac improved upon 802.11n by using wider channel bandwidth (80MHz-160MHz vs 40MHz), Multi-User MIMO (MU-MIMO), 4 simultaneous (not multiplexed) downlinks, beamforming, and more spatial streams (8 vs 4).
