Hi All,
I have (point to point) connection between my office and my ISP using RIC/522T (RB/433 + R52H) the distance is about 4KM line-of-sight (LOS) path , Now I have 10 Mbps of bandwidth my new plan is to upgrade to 18 Mbps of bandwidth, the question is what is the maximum bandwidth which RIC/522T can transfer ? 
\
