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-815DAP 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-815DAP to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the TEW-815DAP 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-815DAP 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 infra-
structure 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.
A
D-HOC (IBSS) NETWORK
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).
To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and
channel for each station.
