Chapter 2 Configuring Radio Settings
Configuring Radio Channel Settings
Use the no form of the client power command to disable the maximum power level for associated clients.
Note Access Point extensions must be enabled to limit the power level on associated client devices. Access
Point extensions are enabled by default.
Configuring Radio Channel Settings
The default channel setting for the wireless device radios is least congested; at startup, the wireless
device scans for and selects the least-congested channel. For the most consistent performance after a site
survey, however, we recommend that you assign a static channel setting for each access point. The
channel settings on the wireless device correspond to the frequencies available in your regulatory
domain. See the access point’s hardware installation guide for the frequencies allowed in your domain.
Each 2.4-GHz channel covers 22 MHz. The bandwidth for channels 1, 6, and 11 does not overlap, so you
can set up multiple access points in the same vicinity without causing interference. Both 802.11b and
802.11g 2.4-GHz radios use the same channels and frequencies.
The 5-GHz radio operates on eight channels from 5180 to 5320 MHz. Each channel covers 20 MHz, and
the bandwidth for the channels overlaps slightly. For best performance, use channels that are not adjacent
(44 and 46, for example) for radios that are close to each other.
Note Too many access points in the same vicinity creates radio congestion that can reduce throughput. A
careful site survey can determine the best placement of access points for maximum radio coverage and
throughput.
Step 3
power client
These options are available for
802.11b, 2.4-GHz clients (in mW):
{ 1 | 5 | 20 | 30 | 50 | 100 | maximum}
These options are available for
802.11g, 2.4-GHz clients (in mW):
{ 1 | 5 | 10 | 20 | 30 | 50 | 100 |
maximum}
These options are available for 5-GHz
clients (in mW):
{ 5 | 10 | 20 | 40 | maximum }
Set the maximum power level allowed on client devices that
associate to the wireless device.
Note The settings allowed in your regulatory domain might
differ from the settings listed here.
