We currently have a good quantity of AP93H APs deployed. Since these APs are only single mode, we created another AP Group, replicating the original one, and chagned the LMS "RF Band" to "a". We did this since we were not sure if changing this setting on the live AP Group was going to do anything with the current live environment.
I've done research and testing and it seems that nothing unexpected happens to the live environment when changing this setting, except for placing the single mode APs on the "a" radio.
I just want to cross my Ts to make sure here. Thanks.
