I am curious. How long are these links? Is the clutter apparent at the omni "hub" or on the directional "spokes," both, or neither? Is it 802.11 clutter? Do you think that you are interfering with other operators? Occasionally home APs interfere with the rooftop network I run in Urbana. I am pretty certain that the Urbana rooftop network is (for the most part) invisible to those APs, because the receiver on a home AP is not ordinarily as sensitive as the Senao receivers. This puts our network at a disadvantage getting access to the medium. To compensate for the unevenness in receivers, I have considered raising the energy thresholds for transmit-deferral and for reception, but I have not gotten around to it yet. I don't know if this will help us, let alone the San Diego net, but it is something to consider.
