1.3 MagicLAN Overview
•
The SWL-2000N (for Notebook) is a wireless LAN adapter card that provides wireless connection between
PCs.
•
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
possible.
•
The MagicLAN supports DSSS (Direct Sequence Spread Spectrum). This is a radio technique, which
scrambles the data prior to transmission and uses a correlation technique on receiving 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-2000AP (Access Point) is to transfer information from 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-2000N for Notebook PC is small and portable as a roaming function is provided for users who
need network services while maintaining mobility.
•
The MagicLAN Adapter has three LED’s (Light Emitting Diodes) on the part of the card: Power, Tx, and
Rx. The red Power LED will illuminate when the power is applied. The orange Tx LED and green Rx LED
will illuminate when the date is transmitted out and in respectively.
•
The MagicLAN supports various network software. The network driver is provided to support most
network software such as MS-DOS Packet, Windows 95/98, and Windows NT 3.51/4.0.
