Attribute Meaning
Custom Radio
Frequency Scan
Selection List Check the frequencies that SM has to scan for AP transmissions. See Radio
Frequency Scan Selection List on page 1-201 .
Channel Bandwidth
Scan The channel size used by the radio for RF transmission.
Note
Selecting multiple channel bandwidths will increase
registration and re-registration times.
Cyclic Prefix The cyclic prefix for which AP scanning is executed.
AP Selection Method Operators may configure the method by which a scanning SM selects an AP.
By default, AP Selection Method is set to “Optimize for Throughput”, which
has been the mode of operation in releases prior to 12.0.3.1.
Power Level: AP selection based solely on power level
Note
For operation with a PMP 450m AP, select the Power Level
option
or
Optimize for Throughput: AP selection based on throughput optimization –
the selection decision is based on power level (which affects the modulation
state), channel bandwidth (which affects throughput) and number of SM
registrations to the AP (which affects system contention performance).
Color Code 1 Color code allows you to force the SM to register to only a specific AP, even
where the SM can communicate with multiple APs. For registration to occur,
the color code of the SM and the AP must match. Specify a value from 0 to
254.
Color code is not a security feature. Instead, color code is a management
feature, typically for assigning each sector a different color code. The default
setting for the color code value is 0. This value matches only the color code
of 0 (
not all 255 color codes).
SMs may be configured with up to 20 color codes. These color codes can be
tagged as Primary, Secondary, or Tertiary, or Disable. When the SM is
scanning for APs, it will first attempt to register to an AP that matches one
of the SM’s primary color codes. Failing that, the SM will continue scanning
and attempt to register to an AP that matches one of the SM’s secondary
color codes. Failing that, the SM will continue scanning and attempt to
register to an AP that matches one of the SM’s tertiary color codes. This is all
done in the scanning mode of the SM and will repeat until a registration has
occurred.
