Obtaining Higher Data Rates
The data rate increase obtained by using 802.11n on an Array is incremental,
based on the technologies that are applied and the options that you select:
 Higher encoding rates (Mandatory in 802.11n)
 Spatial Streams (Mandatory, but multiplier varies directly with number of
streams selected.)
 Channel Bonding (Mandatory in 802.11n, apply multiplier to IAP if it is
bonded.)
 Short Guard Interval (Optional)
See Figure 21 to see the 802.11n data rate increase for an IAP. Apply this increase
to the 802.11 a, b or g data rates selected for the Array.
