Federal Communication Commission Interference Statement

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one of the following measures:

 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.
 Consult the dealer or an experienced radio/TV technician for help.

FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.

IMPORTANT NOTE:
FCC Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20cm between the radiator & your body.

This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.

The availability of some specific channels and/or operational frequency bands are
country dependent and are firmware programmed at the factory to match the intended
destination. The firmware setting is not accessible by the end user.

Chapter 1 - Getting Started with the WPC-370L

Congratulations on purchasing the WPC-370L! This manual provides information for setting up
and configuring the WPC-370L. This manual is intended for both home users and professionals.
It is not required to read some of the more technical information in this manual (such as in
“Wireless LAN Networking” and “Configuring Wireless Security”) to operate and enjoy the
WPC-370L. It is included for your reference only.

Transmission Rate (Transfer Rate)

The WPC-370L 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-370L to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the WPC-370L 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-370L 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-370L
operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an
access point, use Ad-hoc (IBSS) mode.

AD-HOC (IBSS) N

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

ETWORK

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).

9

In the ESS diagram below, communication is done through the access points, which relay data
packets to other wireless stations or devices connected to the wired network. Wireless stations
can then access resources, such as a printer, on the wired network.
