3. ESSID
You can use the default ESSID and radio channel unless more than one Palm Server
Router or access points are deployed in the same area. Under this situation, it is advised
that you should use a different ESSID and radio channel for each of Palm Server Router
or access point in order to distinguish from each other. All of the Palm Server Routers and
your wireless LAN card must have the same ESSID to allow a wireless mobile client
roaming between Palm Server Routers. By default, the ESSID is set to
“
Palm_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
built-in on the Palm Server Router. To minimize interference, configure each of the Palm
Server Router 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 the Palm Server Router 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 the Palm Server Router’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 (if you use high traffic networks should use the
shorter preamble type)
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 Threshold
This value should remain at its default setting of 2346. If you encounter inconsistent data
flow, only minor modifications to the value range between 256 and 2346 are
recommended
