Step 2 Enable wireless spectrums.
The lightweight access points support two wireless spectrums: 5 Ghz and 2.4 Ghz. You must enable and
disable speeds in each spectrum, but the speeds do not have to match.
• Enable IEEE 802.11n and IEEE 802.11ac for the 5-Ghz spectrum.
• Enable IEEE 802.11n and IEEE 802.11g for the 2.4-Ghz spectrum.
Note Beacons are sent at the lowest mandatory rate that define the cell size.
When deploying the switch in converged access mode as a hotspot, the lowest data rate should be enabled
to increase coverage gain versus speed. In addition, the recommended data rates are to be used in a
wireless network with good radio frequency coverage. Data rates are contingent upon the nature of your
radio frequency deployment.
Enable Clean Air
Step 3 Enable Clean Air on the switch and on devices that are common in your deployment environment.
The switch detects and reduces radio frequency interference when Clean Air is enabled. Some sources
of interference are jammers, microwave ovens, and bluetooth devices.
