Adjacent Channel Interference Ratio (ACIR) quantifies how much a transmitter's signal impacts a receiver on an adjacent frequency. It combines both the transmitter's leakage (ACLR) and the receiver's selectivity (ACS) into a single value. Network planners use this ratio to determine how closely different carriers can be spaced in the spectrum without degrading each other's performance.
The vendor specs show an ACIR of 35 dB, which means we can safely colocate these radios without massive interference.

A transmitter measurement comparing the power in the main channel to the power leaking into a neighboring channel.
ACS
A receiver measurement defining its ability to process a desired signal while rejecting strong signals on adjacent channels.
