CWDP: Certified Wireless Design Professional v303 — Question 15

What is the most suitable antenna option to be used when designing a WLAN infrastructure with APs mounted on a ceiling with a height of more than 20 feet and having all of the client stations used from the floor?

Answer options

• A. Patch
• B. Dish
• C. Grid
• D. Low-gain dipole

Correct answer: C

Explanation

The Grid antenna is ideal for this scenario because it provides a focused beam and high gain, which is necessary to effectively reach clients on the floor from a significant height. The other options, such as Patch and Low-gain dipole antennas, do not offer the same level of range and directionality needed for this type of installation, while Dish antennas are typically used for long-distance point-to-point connections rather than broad area coverage.
