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
This recommendation allows 20 MHz of separation between one pair of channels and 22.5 MHz
between the other pair. The network planner can use the Spectrum Analysis feature in an SM or
BHS, or use a standalone spectrum analyzer, to evaluate the RF environment. Where spectrum
analysis identifies risk of interference for any of these channels, the planner can compromise this
recommendation as follows:
• Select 2.4375 GHz for the middle channel
• Select 2.455 GHz for the top channel
• Select 2.4175 GHz for the bottom channel
In any case, the plan should allow at least 20 MHz of separation between channels. See Spectrum
Analysis on Page 59.
5.6.5 5.2-GHz Channels
Channel selections for the AP in the 5.2-GHz band depend on whether the AP is deployed in
cluster. Channel selections for the BH are not similarly limited.
5.2-GHz BH and Single AP Available Channels
A BH or a single 5.2-GHz AP can operate in the following channels, which are separated by 5-MHz
increments.
(All Frequencies in GHz)
5.275 5.290 5.305 5.320
5.280 5.295 5.310 5.325
5.285 5.300 5.315
The channels of adjacent APs should be separated by at least 20 MHz. However, 25 MHz of
separation is advised.
5.2-GHz AP Cluster Recommended Channels
Three non-overlapping channels are recommended for use in a 5.2-GHz AP cluster:
(All Frequencies in GHz)
