Attribute
Meaning
Frequency Band
Select the desired operating frequency band.
Frequency Carrier
Specify the frequency for the module to transmit. The default for this
parameter is None. For a list of channels in the band, see the drop-down
list on the radio GUI.
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 Bandwidth is 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.
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).
Subscriber Color
Code Rescan (When
not on a Primary
Color Code)
This timer may be utilized to initiate SM rescans in order to register to an
AP configured with the SM‘s primary color code.
The time (in minutes) for a subscriber to rescan (if this AP is not
configured with the SM‘s primary color code). This timer will only fire
once – if the Subscriber Color Code Wait Period for Idle timer is
configured with a nonzero value and the Subscriber Color Code Rescan
expires, the Subscriber Color Code Wait Period for Idle is started. If the
Subscriber Color Code Wait Period for Idle timer is configured with a
zero value and the Subscriber Color Code Rescan timer expires, the SM
will immediately go into rescan mode
Subscriber Color
Code Wait Period for
Idle
The time (in minutes) for a subscriber to rescan while idle (if this AP is
not configured with the SM’s primary color code). This timer will fire
periodic events. The fired event determines if any RF unicast traffic
(either inbound or outbound) has occurred since the last event. If the
results of the event determine that no RF unicast traffic has occurred
(SM is idle), then the subscriber will rescan.
