How to configure 9800 WLC for max throughput and max spatial streams?

Throughput achieved can be affected by the following factors-

RF environment (Noise, Interference, DFS..)
AP locations
AP mounting locations
AP antennas
AP spatial streams
AP high throughput capabilities
Channel planning
Radio Band to which client is associated on the AP
Channel width of the AP radio
Client capablities
Number of clients associated to the AP
Distribution of the clients associated to the AP (Legacy, Wi-Fi6 Wi-Fi7 and so on)
Applications being used by the clients
RSSI of the client
Roaming between the APs and so on…

Lets us understand how we can configure our Wi-Fi 7 APs to operate at maximum throughput and maximum spatial streams such that Wi-Fi 7 clients can achieve max performance possible.

How to configure High Throughput?

Configuring high throughput ensures that the AP will support maximum supported spatial streams and MCS data rates.

This setting is separately configured for each band under- Configuration>Radio Configuration>High Throughput>Band (2.4 GHz/5 GHz/ 6 GHz)

How to configure maximum spatial streams?

Number of spatial streams the AP will support is configured under radio profile under- Configuration> Tags and Profiles> Radio Profile> Number of antennas to be enabled (can be configured as 0 or 4)
