Usage Guidelines
The ht-radio-profile configures high-throughput settings for networks utilizing the IEEE 802.11n standard, which
supports 40 MHZ channels and operates in both the 2.4 GHZ and 5 GHZ frequency bands.
Most transmissions to high throughput (HT) stations are sent through multiple antennas using cyclic shift diversity
(CSD). When you enable the single-chain-legacydisable-diversity-spreadingparameter, CSD is disabled and only one
antenna transmits data, even if they are being sent to high-throughput stations. Use this feature to turn off antenna
diversity when the AP must support legacy clients such as Cisco 7921g VoIP phones, or older 802.11g clients (e.g.
Intel Centrino clients). Note, however, that enabling this feature can reduce overall throughput rates.
The ht-radio-profile you wish to use must be assigned to a dot11a and/or dot11g-radio-profile. You can assign the
same profile or different profiles to the 2.4 GHZ and 5 GHZ frequency bands. See
519 and "rf dot11g-radio-profile" on page
Example
The following command configures an ht-radio-profile named "default-g" and enables 40MHz-intolerance:
(host) (config) #rf ht-radio-profile default-g
40MHz-intolerance
