Wireless LAN Networking

This section provides background information on wireless LAN networking technology. Consult the
Glossary for definitions of the terminology used in this section.
Transmission Rate (Transfer Rate)
The TEW-672GR provides various transmission (data) rate options for you to select. In most networking
scenarios, the factory default Best (automatic) setting proves the most efficient. This setting allows your
TEW-672GR to operate at the maximum transmission (data) rate. When the communication quality drops
below a certain level, the TEW-672GR 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 TEW-672GR 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 operation mode to
Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use Ad-hoc (IBSS)
mode.

Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations
communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent
Basic Service Set (IBSS).
