Task 6: Configuring radio parameters
Only the frequencies available for your region and the selected Channel bandwidth
(5/10/20) are displayed.
The Radio tab of the AP contains some of the configurable parameters that define how an
AP operates.

Attribute Meaning
Radio Mode Reserved for future modes of operation.
Frequency Band Select the desired operating frequency band.

Channel
Bandwidth
The channel size used by the radio for RF transmission. The setting
for the channel bandwidth must match between the AP and the SM.
The supported Channel Bandwidths are 5, 10 and 20 MHz.
Cyclic Prefix OFDM technology uses a cyclic prefix, where a portion of the end of a
symbol (slot) is repeated at the beginning of the symbol to allow
multi-pathing to settle before receiving the desired data. A 1/16
cyclic prefix means that for every 16 bits of throughput data
transmitted, an additional bit is used.
Frame Period Select the Frame Period in of the radio. The support Frame Periods
are :
• 2.5 ms
Color Code Specify a value from 0 to 254. For registration to occur, the color
code of the SM and the AP
must match. Color code is not a security
feature. Instead, color code is a management feature, typically for
assigning each sector a different color code.
Color code allows you to force a SM to register to only a specific AP,
even where the SM can communicate with multiple APs. The default
setting for the color code value is 0. This value matches only the
color code of 0 (
not all 255 color codes).
