The correct answer is A. 2 Rx or Tx chains = 3 dBi gain. See the full explanation below for the reasoning.
Question
Given: You are evaluating the theoretical and real-world RF gain benefits of transmit and receive features introduced by 802.11n with MIMO. This exercise allows you to quantify the feature's 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)?
Options
- A2 Rx or Tx chains = 3 dBi gain
- B2 Rx or Tx chains = 1 dBi gain
- C2 Rx or Tx chains = 3 dBi gain
- D2 Rx or Tx chains = approx 4-6.5 dBi gain
- EThe theoretical gains offered by each additional radio are different for TxBF and MRC.
