FortiAP G-series models operating in Single 5G mode can make use of the UNII-4 frequency band. The 5.85 GHz-5.925 GHz channels of "169", "173", and "177" become available when configuring the 5GHz radio.
There are a few important points to note about UNII-4 band usage:
- UNII-4 5GHz channels are not available when operating in Dual 5G platform mode.
- Not all countries allow UNII-4 band usage.
- For APs operating in Single 5G platform mode, note the following behavior changes based on Dedicated scan:
When Dedicated scan is enabled, UNII-4 5 GHz channels are available by default. Radio 3 does not work in AP mode and Radio 2 can utilize all UNII-4 5GHz channels.
When Dedicated scan is disabled, you are given an option to enable or disable UNII-4 5GHz.
By default, FortiAP G-series models support UNII-4 5GHz channels when operating in Single 5G mode with Dedicated scan enabled; there is no need to configure anything. You can immediately select channels "169", "173", and "177" when configuring the 5GHz radio.
