1. MagicLAN Installation

1.1 Introduction

Thank you for your purchase of SAMSUNG MagicLAN (SWL-2100X) Wireless LAN
Adapter. This new Adapter series includes two different models: SWL-2100N/E for
PCMCIA-compatible computers and SWL-2100P for PCI-compatible computers. Installing
either card allows the computer to join a wireless network based on the IEEE 802.11b (High
Data Rate) wireless LAN standard. You will be surprised how easy for you are a part of the
network with no bother of twisted cables.

1.2 Technical Background

• What is IEEE 802.11?
The IEEE 802.11 specification is a wireless LAN standard developed by the IEEE (Institute
of Electrical and Electronic Engineering) committee in order to specify an over an air
interface between a wireless client and a base station or Access Point (AP), as well as
among wireless clients. Like other IEEE 802 families, IEEE 802.11 specification addresses
both Physical (PHY) layer and Media Access Control (MAC) layer.

• IEEE 802.11 Physical (PHY) Layer
At the PHY layer, IEEE 802.11 defines three physical characteristics for WLAN: diffused
infrared, direct sequence spread spectrum (DSSS), and frequency hopping spread spectrum
(FHSS). While the infrared PHY operates at the baseband, the other two PHYs operate at the

2.4GHz ISM (Industrial, Scientific, and Medical) band, which can be used for operating
wireless LAN devices without the need of end-user licenses. In order for wireless devices to
be interoperable, they have to be conforming to the same PHY standard.

• IEEE 802.11 Media Access Control (MAC) Layer
The IEEE 802.11 MAC Layer is mainly concerned with the rules for accessing the wireless
medium. There are two network architectures defined: Ad-hoc Network and Infrastructure
Network.

• Ad-hoc Network
Ad-hoc Network is an architecture that supports mutual communication among wireless
clients only. Since Ad-hoc Network does not support access to wired networks , it does not
need an Access Point to be a part of the network. You can use the network immediately after
setting up the operating mode by installing the supplied network driver.

• Infrastructure Network
Infrastructure Network is architecture that provides communication between wireless clients
and wired network resources. An Access Point (AP) and the associated wireless clients
define the transition of data. So a wireless client can access all the services that are
available for a regular wired LAN by using an AP.

• Roaming
Roaming is a service that allows wireless clients to use the network in motion by
automatically changing the connection from an old Access Point to a new Access Point when
the clients enter in a new cell. During roaming the clients may observe the loose connection
or delay in accessing the resources of the network.

• Scanning, Beaconing & ESS ID
When a wireless client is initialized, it is necessary for it to find and communicate with the
correct group of wireless devices, including AP. At this point, it may search for all the
frequency channels and this process is called scanning.

There may be multiple APs and networks operating at the same time. It may be necessary to
ensure that the station joins with the correct network during the scanning process. To achieve
this, each AP is assigned to be part of a logical group called the Extended Service Set (ESS).
The name of this logical group is the ESS ID. When roaming is operating, there may be
several Access Points as part of the same ESS.

After the power on, wireless clients will listen on its default frequency channel. It will be
listening for beacons sent by another wireless station or AP. Beacon is a short message
containing the ESS ID that will be broadcast roughly ten times a second. When the wireless
station hears a beacon and the ESS ID in the beacon matches its own, the client knows that it
is on the correct channel and can communicate with its group. If no beacons are seen, or if the
ESS ID does not match, the wireless client may move to the next frequency channel and
repeat this listening procedure.

In case of direct sequence spread spectrum (DSSS) physical layer, this scanning process
occurs at start up and may also occur when the client roams between APs.

1.3 MagicLAN Overview

• The MagicLAN SWL-2100P (for Desktop PCs) and SWL-2100N/E (for Notebook PCs)
are wireless LAN adapter cards that provide wireless connection between computers.

• The MagicLAN is designed to operate with IEEE 802.11 (wireless LAN International
Standard) wireless compliant radio cards and uses a CSMA/CA (Collision Sense Multiple
Access with Collision Avoidance) algorithm as the media access scheme, which makes high
speed communication (with minimal collision probability) possible.

• The MagicLAN supports DSSS (Direct Sequence Spread Spectrum) physical layer. This is
a radio technique, which scrambles the data prior to transmission and uses a correlation
technique on receiver to improve the signal to noise ratio and makes it possible to
communicate in the office having a wall and a compartment.

• The function of the MagicLAN SWL-2100AP (Access Point) is to transfer information from
