This issue seems surmountable, just make sure the air-capping machine is a) located halfway between the other two hosts in question and b) has better antennas ;) . It should be possible to “degrade” the antenna quality of the two hosts to make sure the air-capper (sounds like a fancy whale species) has better RF visibility…
