Question #1 (Topic: )
AP-1 is a 3x3:2 AP. STA-3 is a 3x3:3 client. What is the maximum number of spatial
streams that can be used for a downlink HT-OFDM transmission from AP-1 to STA-3?
streams that can be used for a downlink HT-OFDM transmission from AP-1 to STA-3?
A. One spatial stream, because the definition of the AP indicates that it is capable of only one spatial stream.
B. Three spatial streams, because the definition of the client indicates that it is capable of only three spatial streams.
C. Two spatial streams, because the definition of the AP indicates that it is capable of only two spatial streams.
D. Three spatial streams, because the definition of the AP indicates that it is capable of only three spatial streams.
Answer: C
