 Show All Channels(5GHz only): When you set the “Regulatory Domain” to “All

Channles”, it will display all the channel numbers regardless of what channel width is

elected. For example, when you select “20MHz” for channel width, check this option

will display channels “36,37,38, 39, 40….” Instead of “36, 40, 44…etc). This allow

you to use a non-standard channel to avoid interference or for privacy purpose.

4.2.9 Channel Width

Operation Mode -> Setup -> Channel Width

In 802.11a spec, each channel occupies 20MHz channel width. Therefore, each channel

will jump by number of 4 (i.e. 36, 40, 44…etc). You can change the Channel Width to

40MHz(Turbo), 10MHz(Half) or 5MHz(Quarter) to either increase performance or reduce

the interference problem.

 Turbo (40MHz): Each channel will use 40MHz, double the normal size, to increase the

performance by channel binding. This option is not allowed in countries inside EU

 Normal (20MHz): This is the default channel width specified by IEEE 802.11a

specification

 Half (10MHz): Using this option will double the available channels for deployment in

congested areas. However, the performance will also drop by half when using this

option. When you are in Client mode, you can put the “Regulatory Domain” to “all

Channels” to maintain compatibility with other AP.

 Quarter (5MHz): Using this option will increase the available channels by 4 times. It

is a good choice for deployment in very congested areas. However, the performance

will also drop greatly when using this option. When you are in Client mode, you can

put the “Regulatory Domain” to “all Channels” to maintain compatibility with other AP.

4.2.10 Security Settings

Operation Mode -> Setup -> Security Settings

Security settings allow you to use encryption to secure your data from eavesdropping.

You can select different security policy to provide association authentication and/or data

encryption. The WHA-5500CPE-NT features various security policies including WEP,

802.1x, WPA, WPA-PSK, WPA2, WPA2-PSK, WPA-Auto, and WPA-PSK-Auto. Please
