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?

  • 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.
