Wireless LANs
BSS (Basic Service Set)
BSS (Basic Service Set)
A group of wireless stations and a single access point, all using the same SSID(service set identifier),
form a Basic Service Set (BSS).
Using the same SSID (service set identifier) 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
channels 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(Extended Service Set)).
•
ESS: In Infrastructure mode, one or more BSS(Basic Service Set) can set up a ESS (Extended
Service Set). User can access and roaming BSS data and the access point should be set to the same
ESSID(Extended Service Set Identifier) to allow roaming.
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 security settings for
each of the following:
