Most IR remotes use one of three frequencies; 36, 38, and 40 KHz. But their light outputs are all the same IR; the sensor will see them all.

IR remotes and their receivers use different codes, not different frequencies. If you're sending one code while someone else is sending another, the chances of either one getting through without errors is very small.

Try this at home: Hold the button on one remote (VCR?) and then try to use another (TV?). Very seldom will it work. There will be up to six robocoaches operating signaling devices during the Hybrid period.
