I'll tell you what we do, but won't get into defending it for the next month -- oh, wait, this is not the Canopy list.......
Our 2.4GHz spectrum is completely filled with vertical Canopy. We run UBNT AP's. Fixed at 2mi ACK. No RTS. Fixed G-only. Horizontal polarity. Max data rate of 54Mbps. Sectors. Customers are all within 2 miles, use Loco2's. Customers are Auto ACK. No RTS. Fixed G-Only. Horizontal. Max 54Mbps. On almost every single install we get at least 12Mbps down, 6Mbps up (our rate limit). Without limit, we usually see up to 18. Funny... those lusers on the other guys Canopy pay like $40/mo for 1.5Mbps. We give 12Mbps for $24.95/mo. Don't use B. It's DSSS. G is OFDM. Performs much better.
