Selecting a Wireless Channel

You may need to change the wireless channel on which the DVW326 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.

Note

To change the wireless broadcast channel, refer to

Using the Wireless Radio Option on

page 68

.

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.

Network Range

Wider range than the 5GHz band

Interference

Higher interference levels compared to the 5GHz band, as many wireless

devices such as cordless phones, microwave ovens, and computers use the

2.4GHz 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.

Band

2.4GHz
