N10-005 Question #333: Real Exam Question with Answer & Explanation

The correct answer is C: Close to the suspended ceiling, but not above.. Mounting WAPs close to the suspended ceiling but below it is optimal because it places the device at height for good omnidirectional coverage while keeping the antenna in the same physical space as the users. The signal radiates outward and downward into the occupied area. Placin

Question

A consultant is installing new WAPs for an office using wall mounts. Which of the following is the BEST location for the new boxes for signal strength and coverage?

Options

AAbove the suspended ceiling with antennas positioned upward.
BClose to the floor level to allow the signal to traverse the floor laterally.
CClose to the suspended ceiling, but not above.
DAbove the suspended ceiling with antennas positioned downward.

Explanation

Mounting WAPs close to the suspended ceiling but below it is optimal because it places the device at height for good omnidirectional coverage while keeping the antenna in the same physical space as the users. The signal radiates outward and downward into the occupied area. Placing WAPs above the suspended ceiling with antennas pointing upward is counterproductive-the signal would radiate away from users and be attenuated by the ceiling tiles. Placing them near the floor limits coverage area because the signal travels along the floor rather than covering the full room. Placing WAPs above the ceiling with antennas pointing downward can work in some plenum deployments but ceiling tile material attenuates the signal unnecessarily, making the below-ceiling mount the better choice for most office environments.
