An access point will be partially exposed to the outdoor environment in a loading dock of a factory. How should this access point be deployed in a cost-effective manner?
A. indoor AP with an external leaky coaxial cable
B. outdoor mesh AP utilizing the 5-GHz band
C. outdoor bridge AP pointing its antenna toward the factory
D. indoor-based AP inside a NEMA-rated enclosure
Correct Answer: B
Explanation/Reference:
Explanation:
Because mesh radio waves have very high frequency in the 5-GHz band, the radio wavelength is small; therefore, the radio waves do not travel as far as radio waves on lower frequencies, given the same amount of power. This higher frequency range makes the mesh ideal for unlicensed use because the radio waves do not travel far unless a high-gain antenna is used to tightly focus the radio waves in a given direction.

READ THE QUESTION … cost-effective manner!
Answer is B
The answer here should be D. indoor AP is much cheaper even if a NEMA-rated enclosure is included compared to buying an outdoor Mesh. If the question is “cost-effective manner”, D is definitely the answer, not B.
D D D D is the right choice:
A. indoor AP with an external leaky coaxial cable – bad idea, used for elevator shafts and mines, why the heck we need that here?
B. outdoor mesh AP utilizing the 5-GHz band – We don’t need a mesh network. Issue is the AP is a bit exposed to the outdoors to how to protect it? outdoor mesh AP will be more expensive and 5Ghz is no needed from any information given.
C. outdoor bridge AP pointing its antenna toward the factory – and how will you connect this? Will be more expense and pointing an antenna toward the factory is not the ideal solution. You need coverage from the loading bay area for collection/delivery so the lorries or scanners get connected.
D. indoor-based AP inside a NEMA-rated enclosure – that’s exactly what we need. A cheapish NEMA box is to protect the AP from the weather. No MESH needed, no bridge AP needed, no leaky cables.
D
Why MESH and 5 GHz?
I’d choose D, NEMA Type-3 is weather resistant. Plastic, of course, and if it’s not cold…
