Chapter 1- Wireless LAN Networking

This section provides background information on wireless LAN networking technology.
The card provides various transmission (data) rate options for you to select. Options include
Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps, 22
Mbps, 24 Mbps, 36 Mbps, 48 Mbps, 54 Mbps and 108Mbps. In most networking scenarios,
the factory default Fully Auto setting proves the most efficient. This setting allows your card
to operate at the maximum transmission (data) rate. When the communication quality drops
below a certain level, the card automatically switches to a lower transmission (data) rate.
Transmission at lower data speeds is usually more reliable. However, when the
communication quality improves again, the card gradually increases the transmission (data)
rate again until it reaches the highest available transmission rate.
Types of Wireless Networks
Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In
infrastructure mode, wireless devices communicate to a wired LAN via access points. Each
access point and its wireless devices are known as a Basic Service Set (BSS). An Extended
Service Set (ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as
peer-to-peer mode), wireless devices communicate with each other directly and do not use
an access point. This is an Independent BSS (IBSS).
To connect to a wired network within a coverage area using access points, set the card
operation mode to Infrastructure (BSS).
