900-MHz Channels
900-MHz AP Available Channels
A 900-MHz AP can operate with its 8-MHz wide channel centered on any of the following
frequencies:
(All Frequencies in MHz)

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.
2.4-GHz Channels
2.4-GHz BHM and AP Available Channels
A 2.4-GHz BHM or AP can operate with its 20-MHz wide channel centered on any of 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

2.4225
2.4350
2.4475
2.4250
2.4375
2.4500
The center channels of adjacent 2.4-GHz APs should be separated by at least 20 MHz.
