Description
From the menu, select the channel width for the radio. Use the following guidelines:
• A wider channel improves the performance.
• The 802.11n specification allows a 40 MHz–wide channel in addition to the legacy
20 MHz channel that is available with other modes.
• The 802.11ac specification allows an 80 MHz–wide channel in addition to the 20
MHz and 40 MHz channels that are available with other modes.
• The 40 MHz and 80 MHz channels enable higher data rates but leaves fewer
channels available for use.
The channel width and guard interval determine the available MCS index and data
transmit rates.
From the menu, select the transmission power of the radio. You can select
100%(Max), 50%, 25%, 12.5%, or 4%(Min). The default is 100%(Max).
Note: If two or more access points are operating in the same area and on the same
channel, interference can occur. In such a situation, you might want to decrease the
output power for the access point. Make sure that you comply with the regulatory
requirements for total radio frequency (RF) output power in your country.
From the menu, select the value that protects radio transmissions from interference.
An Auto guard interval (which is the default) improves performance, but some legacy
devices can operate only with a long –800ns guard interval.
The guard interval and channel width determine the available MCS index and data
transmit rates.
From the menu, select the WiFi channel for the radio. The available WiFi channels
and frequencies depend on the country and the radio. The default is Auto, which
enables the radio to automatically select the most suitable channel.
Note: You do not need to change the WiFi channel unless you experience
interference (which is indicated by lost connections).
Note: If you use multiple access points, reduce interference by selecting different
channels for adjacent access points. We recommend a channel spacing of four
channels between adjacent access points (for example, use Channels 1 and 5, or 6
and 10).
