CWNP CWNA-109 Exam - Topic 3 Question 26 Discussion

Actual exam question for CWNP's CWNA-109 exam
Question #: 26
Topic #: 3
[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

Surprised to see S1G mentioned, thought it was niche.

I think VHT could work in offices too, though.

I’m leaning towards S1G too, but I wonder if HT could also be a contender in some specialized industrial scenarios.

I practiced a question similar to this, and I feel like OFDM is more standard for office use, so it’s probably not the answer here.

I’m not entirely sure, but I remember that VHT is more common in high-density environments, so it might not be the answer.

I think S1G might be the right choice since it’s designed for low-power, long-range applications, which fits industrial settings better.

I'm pretty confident on this one. The S1G PHY is designed for low-power, low-data-rate applications, which makes it a good fit for industrial IoT and automation use cases. The other options like VHT and HT are more geared towards high-throughput office and home networking.

Okay, I think I've got this. Industrial deployments often require more robust and reliable wireless connections, so I'm guessing the S1G option would be the best choice here. The lower frequency and narrower bandwidth should provide better range and penetration for industrial environments.

Hmm, I'm a bit unsure about this one. I know the different 802.11 PHYs, but I'm not sure which one would be more likely in an industrial deployment versus a standard office. I'll have to review my notes.

This question seems to be testing my knowledge of different 802.11 PHY types and their use cases. I'll need to think carefully about the characteristics of each option.

VHT - Very High Testosterone? Hmm, I don't think that's the right answer for an industrial deployment.
