You be right! I have one hub with multiple backhauls on it. My problem was always the sectors being 15 to 19dbi gain but the grids being a good 29. My furthest out is 20 miles, not good for a 15dbi sector, but most other AP's can see the hub's sectors at at least a -74. In fact, I've USED them in a pinch to work around outages, though not within FCC guide lines.......... (So what) but I never thought about just using it as part of the big vision.

I'm working on a design now that has 15-20 access points fed from a sector antenna on a tower. (I couldn't put that many separate links up if I tried, not between 5.725 and 5.85.) They'll need TDMA (Airmax or an Nstreme) to keep things sorted out, of course. There's a string of nodes that can barely see each other for the trees, but can all see one tower over water... since water paths tend to be flakey, I'm thinking of putting two antennas on the tower, one above the other, hoping that the vertical spacing may have the two sectors (overlapping coverage, different 5.8 channels) flake out at different times. The real question is whether or not I can make a case that the "Sky Pilot Rule" applies, and thus the whole sector counts as PtP for regulatory power limit purposes. With TDMA it's only transmitting to one at a time, after all... -- Fred Goldstein k1io fgoldstein "at" ionary.com ionary Consulting http://www.ionary.com/ +1 617 795 2701 ---------------------------------------------------------------------------- ---- WISPA Wants You!
