expected througput with sr5 or xr5 and rb532a

Hello,

Could anyone give me some insight as to what kind of throughput I could expect with this type of configuration?

rb532
sr5 or xr5 card
LOS
Links vary from 6 to 18 miles.

I want to use this equipment to replace existing links that I have that are currently pushing up to 20mbit half duplex. I’m not looking for more speed, just reliability.

Thanks,
Dan.
