802.11a
The 802.11a mode can support data rate up to 54Mbps (6, 9, 12, 18, 24, 36, 48, 54Mbps). The
802.11a uses 5-GHz UNII (Unlicensed National Information Infrastructure) frequency band. The
use of 5-GHz UNII frequency band provides some distinct advantages over the 2.4GHz band. In
addition to providing a greater amount of bandwidth for transmission, the 5-GHz band has less
potential interference because lots of wireless device working in the 2.4GHz band (Bluetooth,
cordless telephone, microwave ovens, and so on)

802.11a Turbo (This mode is not allowed for outdoor use, so has been removed from
wireless mode menu)
The 802.11a Turbo mode can support data rate up to 108Mbps (72, 96, 108 Mbps).
6.1.4 Channel Number
The channel number is a means of assigning frequencies to a series of access points. If you are using
the WH-9000MESH as both an AP and bridge, the channel number set for the AP and the one for
bridge should be sufficiently different to avoid interference. Generally, it has been found that the
selection channel 4 for bridging and channel 11 for AP gives a good spread at 2.4GHz band, or one use
2.4GHz band and another one use 5GHz band.
Before you setting the channel, you had better to use the optimal channel function to detect the
environment’s radio signal and choose the best one for using.

Optimal channel
If you click on the button “
Select the optimal channel”
, a popup screen will display the choices. After
enter this function, the WH-9000MESH detects the environment’s radio signal at each channel and
show them at this screen. This action does not select the channel for you but shows you what will most
probably be channel selected if you leave the following dropdown menu at Yes.
