How to activate Cyclic Shift Diversity (CSD) on a controller

[Francois Verges]

Hi everyone,

I am working in an environment where I could use the benefits of Cyclic Shift Diversity (CSD).

I know the AP 2602 I am using is compatible with it according to the data sheet. However I don't know how to check if it is activated or not on the controller (5508 v7.6.130).

I configure the controller directly on the GUI interface and I didn't find anything about CSD in the Help guide nor in the WLC Config Guide.

Thank you very much.

François

It is enabled (default),
You can change it to single mode and see the changes in OFDM

config 802.11a antenna diversity sideA <CiscoAP>

verify by doing a "show controller dot11radio1"
Transmit Antennas : right-a left-b, ofdm single
