Information About OFDMA Support for 11ax Access Points
The Cisco Catalyst 9100 series access points are the next generation WiFi 802.11ax access point, which is ideal for high-density high-definition applications. The IEEE 802.11ax protocol aims to improve user experience and network performance in high density deployments for both 2.4 GHz and 5 GHz. The 802.11ax APs supports transmission or reception to more than one client simultaneously using Orthogonal Frequency Division Multiplexing (OFDMA). The IEEE 802.11ax supports uplink MU-MIMO and also adds OFDMA for multiple users in the uplink and downlink. All the users in IEEE 802.11ax OFDMA have the same time allocations and it ends at the same time. In MU-MIMO and OFDMA, multiple stations (STAs) either simultaneously transmit to a single STA or simultaneously receive from a single STA independent data streams over the same radio frequencies.
Supported Modes on 11ax Access Points
The following AP modes are supported: · Local mode · Flex-connect mode · Bridge mode · Flex+Mesh mode

Note For 6-GHz radio, the 802.11ax parameters are taken from the multi BSSID profile tagged to the corresponding 6-GHz RF profile of the AP. So, the WLAN dot11ax parameters are overridden by multi BSSID profile parameters in the case of 6-GHz. There are no changes for 2.4 and 5-GHz band WLANs. They continue to use the WLAN parameters for 802.11ax.
