7731 NLOS perfonmance

Is there any experienced user tell me about 7731's NLOS perfonmance ? Or need an advice about 1.5 km link between two building just for advice, I know conditions are variable and lots of probability can be happen but need experience view.

What do you mean by NLOS. How much stuff is in the way and what kind?

But anyway I don't think you want to be designing a NLOS link at all.

NLOS = Non-line-of-sight, the two building cannot see each other mean, its very common thing to understand.

Thanks for explaining what NLOS means. I wasn't quite sure what the "O" stud for there.

But my question was what grade of NLOS are you talking about?

Generally you should keep the first Fresnel zone clear as much as possible. The more you "shade" it the less performance you will have. I wouldn't be comfortable of designing a link with at least 80% of it clear.

Agreed, 7782 APs may mesh without good LoS, but would not design a 7731 PtP link without LoS visibility at any distance.
