Selecting a Wireless Channel
You may need to change the wireless channel on which the UBC1329AA00
operates when you are in computing, test, and other environments where
several wireless access points may be operating in the 2.4GHz range.
In some cases, you may want to segment your wireless traffic where a group of
devices operates on one channel and another group operates on another
channel, and so on. This is done by configuring the channel on each wireless
access point individually (if you have multiples). If you have control over only
one wireless device in an environment where there may be several, you can
change the wireless channel on your device to one that is not heavily used.
2.4GHz Channels
The following diagram displays the channels available in the Americas. Each
available channel is 22MHz wide. Since channels overlap, it is best to choose
channels that have the least overlap (typically 1, 6, and 11 in the Americas, and 1,
5, 9, and 13 in Europe). Overlapping channels can cause wireless network
performance issues.
Band
2.4GHz
5GHz
Channels
In the USA, channels 1-11 are used. There are 3
non-overlapping channels (1, 6, and 11). Auto
channel should be selected to ensure that the
channel with the least interference is used.
23 non-overlapping channels.
Standards

Network
Range
Wider range
Shorter Range
Interference
Higher, as many wireless devices such as
cordless phones, microwave ovens, and
computers use the 2.4GHz frequency.
Lower chance of picking up interference
because fewer types of wireless devices
use the 5GHz frequency.
Application
Recommended for simple Internet browsing
and email, as these applications don’t take too
much bandwidth and work fine at a greater
distance.
Recommended for applications that
require uninterrupted throughput, like
media streaming. The wider spectrum
delivers better performance.
NOTE:
If you want to use the 5GHz frequency, all wireless client adapters must support 5GHz.
