airMAX AC devices have existed through two separate FCC grants. The first AC devices were shipped under old rules that only allowed use in the UNII3 band. Since airMAX AC’s release, the devices were certified under the new grant that allows the use of UNII1, UNII2, and UNII3.

This has caused some confusion with users who bought early devices and are now deploying newer devices that are certified under the most current rules.

FCC Grant Comparison: Old and New

For example, you may have Access Point (AP) and Station devices that are only using the UNII3 band, and now need to replace the old AP with a new AP. The new AP has the entire 5GHz band enabled, but the older stations do not.

If you set the AP to something outside of the original band 5735 to 5840, your older station devices will no longer connect to that AP.

Here is the frequency scan list of an older device; it is fairly limited by the original grant:


On the other hand, this is the Control Frequency List of a device activated and operating on the newest FCC rules:


The benefit of these new rules is that admins are allowed to choose from many more channels and provides the option to easily work around interference.

Devices currently manufactured are already activated. All airMAX AC devices are allowed to operate under the new rules and it is recommended to activate these rules on all devices to avoid confusion and to have access to a much broader spectrum.
