Wireless LAN Networking

Transmission Rate (Transfer Rate)
The TEW-630APB provides various transmission (data) rate options for you to select. In most
networking scenarios, the factory default Best (Auto) setting proves the most efficient. This
setting allows your TEW-630APB to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the TEW-630APB 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-630APB 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).
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.
