LevelOne WAB-5120 - Manual (Page 37)

Wireless Network Name (SSID)
This wireless network name is shared among all associated devices in your wireless network.
Keep it identical on all those devices. Note that the SSID is case-sensitive and cannot exceed
32 characters.
802.11 Mode
The WAB-5120 can communicate with wireless devices of 802.11n or 802.11a/n.
HT Protect
Enable HT (High Throughput) protect to ensure HT transmission with MAC mechanism. Under
802.11n mode, wireless client can be divided into HT STA and Non-HT STA, among which the one
with HT protect enabled gets higher throughput.
Frequency/Channel
Channel varies much as the available band differs from country to country. Select a proper
operating channel in the drop-down list according to your situation
Extension Channel
Only applicable to AP, AP Repeater, and 40MHz channel width indicates the use of channel
bonding that allows the WAB-5120 to use two channels at once. Two options are available:
Upper Channel and Lower Channel..
Channel Mode
4 levels are available: 40MHz, 20MHz, 10MHz and 5MHz. 40MHz can enhance data throughput,
but it takes more bandwidth, thus it might cause potential interference.
Antenna
By default, the WAB-5120 uses its built-in antenna for directional transmission; however, if you
prefer to use an external antenna for your case-dependent applications, you can switch from
“Internal (16 dBi)” to ”SMA Connector”.
When SMA Connector is selected, an Antenna Gain bar will appear to allow you specify the gain
of the external antenna. The antenna gain calculates the TX power back off needed to remain in
compliance with regulations.
You are able to choose “SMA Connector” only from the WEB UI after you have
physically installed the external antenna; otherwise, it might damage the unit itself.
