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.
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.
