interferences in wireless configuration

dear all,

I have 4 sxt in the same site (tower) directed in the different position but there is more interference one dish can see others ones but the frequencies are not the same “a terrible interference” I’m using (nv2 protocol) bridge**station-bridge
I want to know what configuration do I make for the avoiding the interference
or how to do for the dish A can see only the dish B
(with mac address may be but how)
thanks for your attention

Try to place them into different height. Keep at least 1m between devices. Only different direction is not enough. Regulate the power as much is possible. Keep at least one channel space between used frequencies. If it would not help enough try to put additional shielding between devices.
