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
