Trango is able to do this with all of their radios (which are based on an 802.11 chipset). They call it a "receive threshold" and you set the RSSI level. Anything higher than your setting is totally ignored by the radio. This helps a great deal in noisy environments.

Re: Thoughtput parameters

Your signal level is low for that distance. You should be closer to -56 on both sides. Try different channels. If that doesn't help, your antennas are not aligned properly.

Also, check the CCQ values. They should be 100/100 on both sides.
