Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?
Patch and panel antennas are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation. These types of antennas provide the necessary directionality and coverage within indoor environments, ensuring multiple spatial streams can be effectively utilized. Dipole antennas are not directional while grid, sector, and dish antennas are more commonly used in outdoor or large-area implementations rather than indoor environments.
C. Patch and panel CHAPTER 4 - PAGE 141 (Official Study Guide) "MIMO APs use internal omni-directional or SEMI-DIRECTIONAL (page 137) antennas and, when external antennas are supported, may use PATCH or PANEL antenna arrays."
C, since Patch and Panel are used also used indoors Dipole is not directional and the other options are uncommon for indoor used.
