link capacity test

I dont really care to test for bandwidth as i would like a test that can tell us link% efectiveness… installing blind isnt any fun. And ive had plenty of links in the 70db range fall apart and harq didnt recover… the radio would reboot constantly changing cpes didnt help. Finally we put a 900 in its place… the link % sucked and simply moving the radio fixed the locking up and rebooting… something that would have been good to know before we wasted truck rolls and angry customers
