SSID & Channel
The SSID is an identification string of up to 32 ASCII characters that
differentiate one SpaceLink Home Gateway or Access Point from another.
The SSID is also referred to as the "ESSID" or "Extended Service Set ID."
You can use the default SSID and radio channel unless more than one SpaceLink
Home Gateway or Access Point is deployed in the same area. In that case, you
should use a different SSID and radio channel for each SpaceLink Home
Gateway or Access Point. All the SpaceLink Home Gateways and SpaceLink
802.11b client adapters must have the same SSID to allow a wireless mobile
client to roam between the SpaceLink Home Gateways. By default, the
SSID is set to "default".
Channel
IEEE 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 a Channel.
The IEEE 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 the SpaceLink Home Gateway. To minimize
interference, configure each the SpaceLink Home Gateway to use Non-
overlapping channels. Non-overlapping channels have 25Mhz separation
beginning at the first allowed channel for the country (for the US and most
of Europe, channels 1, 6 & 11 are used).
Make sure that the SpaceLink Home Gateways sharing the same Channel
(or Channels close in number) are 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 SpaceLink PC card or CF card setup CD.
Rate
Select "1, 2, 5.5 & 11Mbps" to maximize performance. Use "1 & 2 Mbps"
only when backward compatibility is needed for some older wireless LAN
cards with a maximum bit rate of 2Mbps.
The IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5 Mbps,
2 Mbps, and 1 Mbps. As a wireless mobile client travels further and further
away from the SpaceLink Home Gateway, the data rate automatically decreases
in order to maintain a usable radio connection. Therefore, a client that is close
to an the SpaceLink Home Gateway may operate at 11 Mbps, but a client that
is far away from the SpaceLink Home Gateway may operate at 2 Mbps.
