The Radio tab of the AP contains some of the configurable parameters that define how
the AP operates. As shown in Figure 77, you may set the Radio tab parameters as
follows.
Radio Frequency Carrier
Specify the frequency for the module to transmit. The default for this parameter is None.
(The selection labeled Factory requires a special software key file for implementation.)
For a list of channels in the band, see the drop-down list or Considering Frequency Band
Alternatives on Page 136.
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 an SM to register to only a specific AP, even where the
SM can communicate with multiple APs. On all Cyclone modules, the default setting for
the color code value is 0. This value matches only the color code of 0 (not all 255 color
codes).
RECOMMENDATION:
Note the color code that you enter. Ensure that you can readily associate this
color code both with the module and with the other data that you store about the
module.
Sector ID
Specify a number in the range 1 to 6 to associate with this AP. The Sector ID setting
does not affect the operation of the AP. On the AP Evaluation tab of the Tools page in
the SM, the Sector ID field identifies the AP that the SM sees. The following steps may
be useful:
• Assign a unique Sector ID to each sector in an AP cluster.
• Repeat the assignment pattern throughout the entire Cyclone system.
Max Range
Enter a number of miles (or kilometers divided by 1.61, then rounded to an integer) for
the furthest distance from which an SM is allowed to register to this AP. Do not set the
distance to any greater number of miles. A greater distance
• does not increase the power of transmission from the AP.
• can reduce aggregate throughput. See Table 24 on Page 100.
Regardless of this distance, the SM must meet the minimum requirements for an
acceptable link. If the AP is in cluster, then you must set this parameter on all other APs
in the cluster exactly the same, except as described in the NOTE admonition below.
The default value of this parameter is 2 miles (3.2 km).
For APs in the non 900-MHz frequency band ranges, although the typical maximum
range where an SM is deployed with a reflector is 15 miles (24 km), you can set this
parameter to as far as 30 miles (48 km). Without increasing the power or sensitivity of the
