A company is deploying a new wireless network and requires 800Mbps network throughput. Which
of the following is the MINIMUM configuration that would meet this need?
A.
802.11ac with 2 spatial streams and an 80MHz bandwidth
B.
802.11ac with 3 spatial streams and a 20MHz bandwidth
C.
802.11ac with 3 spatial streams and a 40MHz bandwidth
D.
802.11ac with 4 spatial streams and a 160MHz bandwidth
Explanation:
how is this broken down?

Number of | 802.11n | 802.11n | 802.11ac | 802.11ac
Streams | 20MHz | 40MHz | 80MHz | 160MHz
—————————————————–
1 | 75mbps | 150mbps | 433mbps | 867mbps
2 | 150mbps | 300mbps | 867mbps | 1.7gbps
3 | 220mbps | 450mbps | 1.3gbps | 2.6gbps
