I did see the subject line. A -76 in the middle of nowhere should have fared better than 6% of system capacity.

I would suspect free space loss would be a major factor. On Mon, Aug 10, 2015 at 8:36 AM, Mike Hammett < af...@ics-il.net > wrote: Am I reading that right, 45 MHz for 30 megabit?

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. Join the Conversation Cambium Networks Community Forum -- Lewis Bergman 325-439-0533 Cell
