7. Access the Link Test page of the module.
8. Assess whether the desired links for this module achieve
• uplink efficiency greater than 90%.
• downlink efficiency greater than 90%.
9. If the desired links fail to achieve any of the above measurement thresholds, then
a. access the module by direct Ethernet connection.
b. access the Configuration page of the module.
c. in the Power Control parameter, click Full.
d. click Save Changes.
5.5.4 2.4-GHz AP Channels
Channel selections for the AP in the 2.4-GHz band depend on whether the AP is deployed in
cluster. Channel selections for the BH are not similarly limited.
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
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.
