Appendix B: About Wireless LANs

B.1 BBS

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.

B.2 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.)

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.

B.3 Security

B3.1 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
