CWNP CWDP-305 Exam - Topic 1 Question 19 Discussion

You have performed a validation site survey after deploying a WLAN infrastructure that is an All-Wireless-Office. One specific application of yourcustomer is experiencing delay when using the application after moving from wired connectivity. After your validation, you realized that all APs areusing 80 MHz channel- widths instead of 20 MHz on the 5 GHz band, as it was designed. What can be done to resolve the delay on thisapplication?
B) Reconfigure to use 20 MHz channel-widths, so reuse of the frequency is more effective
A) APs should be using 160 MHz channel-widths to get more throughput
C) Power-off half of the APs to reduce CCI and keep 80 MHz channel-widths
D) Add more APs using 80 MHz channel-widths

I feel like C is risky. Powering off APs could leave dead zones.

A could work, but it might cause more congestion.

But what about option A? 160 MHz could boost throughput.

I think option B is the best choice. 20 MHz will reduce interference.

Adding more APs with 80 MHz? That could just make it worse!

Wait, why would you use 160 MHz? That sounds risky!

Totally agree, 80 MHz is too wide for that setup!

I’m a bit confused about the impact of turning off APs. I think option C could help, but I’m not sure if it’s the best solution overall.

If I recall correctly, reducing the channel width to 20 MHz could help with the delays by minimizing co-channel interference. That seems like a solid choice.

I'm not entirely sure, but I think using 160 MHz might actually cause more problems with congestion. I feel like we practiced a question similar to this.

I remember we discussed how wider channels can lead to more interference, especially in dense environments. So, I think option B makes sense.
