CWNA: Certified Wireless Network Administrator v107 — Question 12

Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

Answer options

• A. Dish and grid
• B. Dipole and yagi
• C. Grid and sector
• D. Patch and panel

Correct answer: B

Explanation

The correct answer is B, as dipole and yagi antennas are known for their effective directional capabilities, which are beneficial in MIMO configurations. Options A, C, and D contain antennas that are either not commonly used in indoor Wi-Fi setups or do not provide the necessary characteristics for MIMO implementations.
