CHAPTER 6: ABOUT WIRELESS LANS
6.1.
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.
6.2.
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.
6.3.
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:
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.
