• Question 125:

  Given: You are evaluating the theoretical and real-world RF gain benefits of transmit and receive features introduced by 802.11 with MIMO. This exercise allows you to quantify the features value in a real-world environment. What is the maximum theoretical signal gain of chip-based TxBF and MRC (as features) when compared to the same AP using only a single antenna for transmit and receive (effectively simulating a 1x1 chip)?

  A. 2 Rx or Tx chains = 3 dBi gain 3 Rx or Tx chains = approx 5 dBi gain 4 Rx or Tx chains = 6 dBi gain
  B. 2 Rx or Tx chains = 1 dBi gain 3 Rx or Tx chains = 2 dBi gain 4 Rx or Tx chains = 3 dBi gain
  C. 2 Rx or Tx chains = 3 dBi gain 3 Rx or Tx chains = 6 dBi gain 4 Rx or Tx chains = 9 dBi gain
  D. 2 Rx or Tx chains = approx 4-6.5 dBi gain 3 Rx or Tx chains = approx 7-10 dBi gain
  D. 2 Rx or Tx chains = approx 4-6.5 dBi gain 3 Rx or Tx chains = approx 7-10 dBi gain

• Question 126:

  Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?

  A. Free space path loss causes greater signal dispersion for higher rate transmissions.
  B. Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding.
  C. To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.
  D. Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.
  B. Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding.

  A. 4# dipole
  B. Yagi
  C. Dish
  D. Horn
  C. Dish

• Question 130:

  When performing a spectrum analysis walkthrough of a facility tor which you will be creating a WLAN design you detect an interferer What should you do?

  A. Make a mental note of it so that you can include it in your design
  B. Make note of it using the reporting features of your spectrum analyzer or by documenting it elsewhere
  C. Locate and remove the interferer immediately so that your WLAN works well
  D. Walk away from the project because it is best to only deploy in clean environments with no other RF signals
  B. Make note of it using the reporting features of your spectrum analyzer or by documenting it elsewhere
