MikroTik

I have a link between the provider edge. I want to establish a connection between Provider to my client location. the distance between the provider edge to my location 12 KM.( non line of site). I want to establish a point-to point connection.
what is the best router boards for me.
guide me plz...
Thank in advance..

At that distance with NLOS I don't think it is going to work.

You may want to look at installing a repeater in the middle of the two sites, if you do not have LOS, you loose throughput and performance very quickly.
