I would guess that SAF's calculations are based on Vigants-Barnett and your LinkPlanner results used ITU-R. You can toggle LinkPlanner to Vigants-Barnett in the Project Properties window.

I have a couple of exisitng 5GHz links I'm looking at replacing with a licensed solution - one of which is about 27 miles. According to LinkPlanner this shot should be no problem (granted not with more than 3 9s of uptime, which is fine considering I have redundancy via another path) using 3 foot dishes, but the SAF engineers are telling me my only option is 6GHz with 6 foot dishes using the same parameters. The best the engineers at SAF could promise was about 150Mbps on Integra, whereas according to LinkPlanner I can get over 800Mbps using an 820s. Is LinkPlanner this far off, or are there some special knobs I need to turn to get real-world results? Or is Cambium somehow that much superior to the other products out there? -- Rory McCann MKAP Technology Solutions Web: www.mkap.net
