Transmission Rate (Transfer Rate)
The WPC-370A provides various transmission (data) rate options for you to select. In most
networking scenarios, the factory default Fully Auto setting proves the most efficient. This
setting allows your WPC-370A to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the WPC-370A 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 WPC-370A 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 WPC-370A
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
7
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.
8
When a number of wireless stations are connected using a single access point, you have a Basic
Service Set (BSS).
