Note: 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 inter-
ference 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 or more 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/TC technician for help.

Thank you for your purchase of SAMSUNG MagicLAN. Installing this cards allow the
computer to join a wireless network based on the IEEE 802.11b (High Data Rate) WLAN
standard. You will be su rprised 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
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), an d frequency hopping spread spectrum
(FHSS). While the infrared PHY operates at the baseband , the other two PHYs operate at
the 2.4GHz ISM (Industrial, Scientifi c, and Medical) b and, wh ich can be u sed for operatin g
wireless LAN devices without the need of end-user licenses. In order for wireless devices to
be interopera ble, 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
over an air
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, i t 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 su pplied network driver.
9
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
10
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
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 th e 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
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
beacons
sent by another wireless station or AP. Beacon is a short message

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-2200M/P
•
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

communicate in the office having a wall and a compartment.
The function of the MagicLAN Access Point is to transfer informatio n fro m a wired LAN
•
to a wireless LAN and vice versa. When operating, the MagicLAN AP is invisible to most
users (Normally, unless the user is an administrator, the MagicLAN AP cannot be seen or
accessed by users on the network).
The SWL-2200M/P both for Laptop PC and Desktop PC is small and portable as a
•
roaming function is provided for users who need network services while maintaining
mobility.
The MagicLAN supports various network software. The network driver is provided to
•
support network so ftware such as Windows 95(OSR2), Windows 98/98SE,ME, W indows
NT 4.0, Windows 2000, Windows XP, Windows CE and Linux.
