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.
z 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.
z 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 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
z 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
security settings for each of the following:
