Ha! I bet the answer is 3.6m. My dog could figure that out, and he's not even an engineer.

Wait, isn't the Fresnel zone radius supposed to be inversely proportional to the square root of the frequency? 6.2m sounds about right.

Yes, that's correct. So in this case, with a frequency of 5GHz, a radius of 6.2m for the Fresnel zone makes sense.

I think you're right, the Fresnel zone radius is indeed inversely proportional to the square root of the frequency.

Hmm, I'm not sure about this one. Gotta double-check my notes on Fresnel zones.

The Fresnel zone radius is definitely 5.6m. This is basic antenna theory!
