CWNP Exam CWDP-303 Topic 1 Question 64 Discussion

Actual exam question for CWNP's CWDP-303 exam

Question #: 64
Topic #: 1

What is the best method of gathering attenuation measurements from any building materials or objects?

AAfter measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall or object on one side and your measuring device 0.67 meters (2 feet) away from the wall or object on the other side. Take measurement and compare the difference.

BUse the pre-built attenuation values in the predictive design tool.

CAfter measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall or object on the other side. Take measurements and compare the difference.

DLook on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material provider's websites.

I'd go with A. It's a bit more work, but you're getting the actual attenuation measurement instead of relying on someone else's numbers.

Yeah, it's always better to measure it yourself rather than rely on pre-built values.

I prefer option D, looking up attenuation values online is more convenient.

Haha, option C sounds like it's just asking for trouble. Putting the AP that close to the wall? That's a recipe for disaster.

I think B is the easiest option, but you might not get the most accurate results. Relying on pre-built values could miss some nuances of the specific environment.

D is interesting, but I don't know if I trust the attenuation values on the material provider's websites. They might have a vested interest in downplaying the effects.

Option A seems like the way to go. Measuring the RSSI in free space and then comparing it to the measurement with the wall or object in between sounds like a reliable method.
