  1. True
  2. False

Question 7

This figure shows how wireless information is transmitted from the signal source to the signal destination over channels. From top to bottom, sort the steps in the order in which they occur during the information transmission process.

Question 8

Which of the following statements about the theoretical rate and attainable rate in 802.11 standards are true? (Choose all that apply.)

  1. The theoretical rate is the maximum rate calculated using an 802.11 standard.
  2. The actual rate is the maximum theoretical rate of a STA when the external interference is ignored.
  3. The theoretical rate is the maximum rate that an AP can reach when there is no external interference.
  4. The attainable rate is the actual rate supported by a product that is developed by a vendor using a certain 802.11 standard.

Question 9

To achieve higher bandwidth, 802.11ax adopts most 802.11ac technologies and introduces OFDMA to redefine modulation multiplexing to support wider subcarrier spacing.
