I recall reading that WBANs are typically used for close proximity, so 10 centimeters might be too short. I’m leaning towards the 1-2 meters option.

I practiced a question like this, and I think the answer was 10 meters. But I’m not completely confident about that.

I’m not entirely sure, but I feel like I saw something about 10 square meters in my notes. That seems a bit larger though.

I think I remember WBANs being pretty short range, maybe around 1-2 meters? That sounds familiar.
