3. ESSID
You can use the default ESSID and radio channel unless more than WE-1120 or Access
Point is deployed in the same area. Under this situation, you should use a different
ESSID and radio channel for each WE-1120 or Access Point. All WE-1120 and your
wireless LAN card must have the same ESSID to allow a wireless mobile client to roam
between WE-1120s. By default, the ESSID is set to “ BT_Server_Router ”.
4. TxRate
Select the transmission rate for the network. The default setting is Auto.
5. Channel
IEEE 802.11g and 802.11b devices are direct sequence spread spectrum devices that
spread a radio signal over a range of frequencies. The range of frequencies used by a
direct sequence device is called Channel.
The 802.11g and 802.11b specification supports up to 14 overlapping Channels for radio
communication. But only 11 Channels are supported in the United States and therefore
on WE-1120. To minimize interference, configure each WE-1120 to use Non-overlapping
channels. Non-overlapping channels have 25 MHz separation beginning at the first
allowed channel for the country (for the US and most of Europe, channel 1, 6 & 11 are
used.)
Make sure that WE-1120 sharing the same Channel (or Channels close in number) is as
far away from each other as possible, based on the results of your site survey of the
facility. You can find the site survey utility in WE-1120’s setup CD. By default, the channel
is “ 6 ”.
6. Hide SSID
This term is used to increase the security level. Check it to hide SSID information against
the wireless clients that are sniffing radio. By default, this option is inactive.
7. TxPreamble
The default TxPreamble setting is Long.
8. Beacon Interval
Beacons are packets sent by an access point to synchronize a wireless network. Specify
a beacon interval value. Default (100) is recommended.
9. RTS Threahold
This value should remain at its default setting of 2346. If you encounter inconsistent data
