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 semi-directional coverage suitable for indoor environments where coverage needs to be managed more precisely, unlike dipole or yagi antennas which are less typical for such implementations.
As "semi" directional antenna that use MIMO, the option to choose would be D, patch and panel. In addition, MIMO is not required in implementations that use Yagi.
i choose D
Answer should be D.
D is correct. According to p144 of the Official Study Guide, "It is also assumed that MIMO is not required when Yagi antennas are used. MIMO patch and panel antennas are available, but MIMO Yagi is not a typical installation."
D is the answer
