Channel selections for the AP in the 2.4-GHz band depend on whether the AP is
deployed in cluster.
12.3.1 900-MHz Channels
12.3.2 900-MHz Single AP Available Channels
A single 900-MHz AP can operate with the 8-MHz wide channel centered on any of the
following frequencies:
(All Frequencies in MHz)
906 907 911 915
919 923 924
900-MHz AP Cluster Recommended Channels
Three non-overlapping channels are recommended for use in a 900-MHz AP cluster:
(All Frequencies in MHz)
906 915 924
This recommendation allows 9 MHz of separation between channel centers. You can use
the Spectrum Analysis feature in an SM, or use a standalone spectrum analyzer, to
evaluate the RF environment. In any case, ensure that the 8-MHz wide channels you
select do not overlap.
12.3.3 2.4-GHz Channels
2.4-GHz BH and Single AP Available Channels
A BH or a single 2.4-GHz AP can operate in the following channels, which are separated
by only 2.5-MHz increments.
(All Frequencies in GHz)
2.4150 2.4275 2.4400 2.4525
2.4175 2.4300 2.4425 2.4550
2.4200 2.4325 2.4450 2.4575
2.4225 2.4350 2.4475
2.4250 2.4375 2.4500
The channels of adjacent 2.4-GHz APs should be separated by at least 20 MHz.
2.4-GHz AP Cluster Recommended Channels
Three non-overlapping channels are recommended for use in a 2.4-GHz AP cluster:
(All Frequencies in GHz)
2.4150 2.4350 2.4575
