ABOUT WIRELESS LANS
BSS
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.
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 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.)
Note to US model owner: To comply with US FCC regulation, the country
selection function has been completely removed from all US models. The above
function is for non-US models only.
Security
WEP
WEP (Wired Equivalent Privacy) is a standard 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.
If WEP is used, the Wireless Stations and the Access Point must have the same settings
for each of the following:
WEP 64 Bits, 128 Bits.
Key
For 64 Bits encryption, the Key value must match.
For 128 Bits encryption, the Key value must match.
WEP Authentication Open System or Shared Key.
