What about 5 GHz UNII-2 and 3? Seems safer.

I vote for D. UNII-1 and 2 seem like a good compromise.

I feel like E is overkill. UNII-1, 2, and 3? Too much!

But what about B? UNII-2 and 3 could be risky too.

I prefer A. Just UNII-2 and 2e should be enough.

I think we should avoid C. All those bands could interfere.

UNII-1 is usually safe, right?

Wait, radar on WLAN? That sounds fishy.

I'd avoid 5 GHz UNII-2 and 3 for sure.

I believe the answer is C, since radar detection is a concern for all of UNII-2 and 2e, but I’m not entirely confident about UNII-3.

I’m a bit confused about the options. I thought UNII-1 was safe, but I can't recall if we should avoid UNII-3 as well.

I think we practiced a similar question where we had to identify which bands were radar-sensitive. I feel like it was definitely UNII-2 and 2e.

I remember we discussed avoiding the UNII-2 bands because they can be affected by radar, but I'm not sure if that includes UNII-3 too.
