Appendix B
About Wireless LANs
This Appendix provides some background information about using Wireless
LANs (WLANs).
Modes
Wireless LANs can work in either of two (2) modes:
• Ad-hoc
• Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-
tions (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations
(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations
can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
BSS/ESS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a
Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate
with each other.
ESS
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form
an Extended Service Set (ESS).
Different Access Points within an ESS can use different Channels. In fact, to reduce interfer-
ence, it is recommended that adjacent Access Points SHOULD use different channels.
As Wireless Stations are physically moved through the area covered by an ESS, they will
automatically change to the Access Point which has the least interference or best performance.
This capability is called Roaming. (Access Points do not have or require Roaming capabilities.)
B
Appendix B - About Wireless LANs
19
Channels
The Wireless Channel sets the radio frequency used for communication.
• Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channels are available. If using multiple Access Points, it is better if adja-
cent Access Points use different Channels to reduce interference.
• In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest signal
is used. (This can only happen within an ESS.)
• If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
WEP & WPA-PSK
Both WEP and WPA-PSK are standards for encrypting data before it is transmitted.
This is desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless
unless the receiver can decrypt it.
WPA-PSK is a later standard than WEP, and is more secure.
WPA2-PSK
This is a later version of WPA (WPA-PSK). The major change is the use of AES (Advanced
Encryption System) for protecting data. AES is very secure, considered to be unbreakable. The
PSK (Pre-shared Key) must be entered on each Wireless station.
If WPA2-PSK is used, the Wireless Stations and the Access Point must have the same
settings for each of the following:
WPA2 PSK
(Pre-shared Key) Enter the same value on every station and the AP. The PSK
must be from 8 to 63 characters in length. The 256Bit key
used for the actual encryption is derived from this key.
Encryption The same encryption method must be used. The most
common encryption method is TKIP. Another widely-
supported method is AES.
Wireless Adapter User Guide
20
Wireless LAN Configuration
To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point
must use the same settings, as follows:
Mode On client Wireless Stations, the mode must be set to "Infrastructure".
(The Access Point is always in "Infrastructure" mode.)
SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access
Point they wish to connect to. Alternatively, the SSID can be set to "any"
or null (blank) to allow connection to any Access Point.
Security The Wireless Stations and the Access Point must use the same settings
for Wireless security (Disabled, WEP, WPA-PSK, WPA2-PSK, WPA
Radius, WPA2 Radius)
• If Wireless security remains disabled on the Access Point, all
stations must have wireless security disabled.
• If Wireless security is enabled on the Access Point, each station
must use the same settings.

Channel
The Wireless Channel sets the radio frequency used for communication.
•Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent
Access Points use different Channels to reduce interference.
• In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest
signal is used. (This can only happen within an ESS.)
• If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
