Your explanation is correct but doesn't exactly match the buggy
behaviour of our wireless hardware/firmware. As far as I can tell, the
ad-hoc nodes in our setup make no attempt to synchronize
clocks/beacons, nor do they stop transmitting their own beacons in the
presence of another node transmitting beacons too. I guess this is why
our ad-hoc networks perform slower and less reliably than the XO-1
mesh, which at least had synchronization.
