I'm looking at getting on a tower with well over 20 miles of line of site to the north. What are the odds of a point to multipoint situation, 12.5dBi + r52h for 36dB with a Crossroads and 24dBi grid as the CPE for a 20 mile shot with line of site? In theory, the math works out, should work. I have my doubts, of course...

On that same note, what is the farthest 2.4GHz client you have without resorting to p2p?

I have a few customers at 20-24 miles from a 15dBi sector with an XR2 on a tower that is ~500ft agl.. The client sides are using 19dBi arc wireless integrated panel antennas and XR2s mounted 15-20ft agl with perfect LOS. I turn the XR2's down on both client and tower to stay within legal limits. Signals vary between mid 60's to mid to upper 70's..

Excellent. I was wondering if anyone would respond.

OH!, I forgot to mention one important thing, I'm using 5mhz channels on my whole network..

I was debating between 5 and 10 myself. I like the added range, but also the capacity of the 10MHz. I'll have to do some testing once I get some elevation for the antennas.

We have customers as far as 15 miles or so from 130-150 foot AP sites, with 26dBm CPE using 24dBi antennas.
