I tried using their data sheet, but after putting in the CAPTCHA two or three times, I found out the sheet didn't have the information I wanted anyway.

Public Safety will pay those kind of ridiculous license fee structures while I don't think anyone who needs most or all of a link from the beginning will. Maybe they looked at their financials and figured they would make up the lost revenue from WISPS and carriers with that Public Safety segment. Not sure about the -76 and throughput. To lazy to do the math to figure what QAM that should be. I should restate that....I am to lazy to learn how to do the math to determine what the QAM should be at -76.

It's also not represented accurately in their literature. IE 100mbps license is not license for 100mbps, it's a license for a certain fraction of the over the air rate and IMO it should be labeled and sold as such.

Ran the link at 5, 30 and 45 MHz channels and had receive signals of approximately -76 dBm even while battling some pretty heavy winds. We were running a high-def video link and a VoIP server over the channel. Consistently stayed above 30 Mbps which is what we had designed the link for. The link was established with both PTP 650 and PTP 700. The link came up fast and we were testing out the applications after less than an hour on site. LINKPlanner does take the curvature of the earth (and altitude) into consideration.
