Topic #: 5
[All CWNA-109 Questions]

Which one of the following 802.11 PHYs is more likely to be used in an industrial deployment but not likely to be used in standard office deployments?

Show Suggested Answer Hide Answer
Suggested Answer: A

S1G is one of the 802.11 PHYs that is more likely to be used in an industrial deployment but not likely to be used in standard office deployments. This is because S1G stands for Sub-1 GHz, which means it operates in the frequency bands below 1 GHz, such as 900 MHz and 868 MHz. These bands offer better penetration and range than the higher frequency bands used by other 802.11 PHYs, such as 2.4 GHz and 5 GHz. This makes S1G suitable for industrial applications that require robust and reliable wireless communication in harsh environments, such as factories, warehouses, mines, and smart grids. S1G also supports low-power and low-data-rate devices, such as sensors, actuators, and meters, which are common in industrial Internet of Things (IoT) scenarios.VHT, OFDM, and HT are other 802.11 PHYs that are more commonly used in standard office deployments, as they offer higher data rates and capacity than S1G, but have lower range and penetration.Reference:CWNA-109 Study Guide, Chapter 3: Radio Frequency Technologies, page 751

S1G? Is that like a secret agent code name or something? Sounds like it would be perfect for a spy mission, not an office network.

HT, all the way! It's like the Swiss Army knife of 802.11 PHYs - versatile enough for both office and industrial use.

Haha, VHT? What is this, a disco tech? Definitely not the industrial vibe I'm looking for.

I'm going with OFDM. It's the classic for office deployments, but I doubt it's the best choice for industrial settings.

S1G, really? That's like using a sledgehammer to crack a nut in an office setting. Definitely more suitable for industrial applications.

S1G is definitely overkill for office settings, better suited for industrial use.

That makes sense, OFDM is known for its robustness in harsh environments.

I disagree, I believe the answer is C) OFDM because it is more commonly used in industrial settings.
