1 Introduction

Wireless LAN is local area networking without wires, which uses radio frequencies to transmit and receive

data between PC’s or other network devices. Wireless LAN is able to configure independent networks

and infrastructure networks. The former is suitable for small or temporary peer-to-peer configurations, and

the later is offering fully distributed data connectivity via micro cells and roaming.

The Wireless LAN card is designed to meet the mobility, performance, security, interoperability,

management, and reliability requirements of IEEE 802.11b high data rate standard. It is easy to install the

Wireless LAN card on various devices with PCMCIA type II card slot. It is able to communicate with

other IEEE 802.11b compatible products to create a wireless LAN in your office or home.

1.1 Features

Ÿ Compliant with 11 Mbps 802.11b high-speed specification.

Ÿ Data rate 11/5.5/2/1 Mbps automatic fallback under noisy environment.

Ÿ Advanced Power Management for battery saving.

Ÿ Supports Windows 95/98/ME/NT/2000/XP

Ÿ Interoperable with IEEE 802.11b compliant equipment.

Ÿ Supports full mobility and seamless roaming from cell to cell.

Ÿ Plug-and-play installation and easy client management with utility software.

Ÿ Supports point-to-point and point-to-multipoint access.

Ÿ Direct Sequence Spread Spectrum (DSSS) technology provides robust, interference-resistant and secure wireless

connection.

Ÿ Wireless connection without the hassles and cost of cabling.

Ÿ Greater flexibility to locate or move networked PC’s.

1.2 Applications

Ÿ Home networking for device sharing - Remote access to corporate network information email, file transfer and terminal

emulation.

Ÿ Frequently changing environments - Retailers, manufacturers and banks that frequently rearrange the workplace and

change location.

Ÿ SOHO (Small Office and Home Office) users - SOHO users need easy and quick installation of a small computer network.

Inter-building connection - The wireless building-to-building network installs quickly, requires no monthly lease fees, and

provides the flexibility to reconfigure easily.

Typical applications include hard-to-wire buildings, campuses, hospitals/medical offices, warehouse, security huts,

exhibition centers, etc.

Temporary LANs for special projects or peak time - Auditors require workgroups at customer sites. Trade shows,

exhibitions, retailers, airline, and shipping companies need additional workstations for a peak period.

1.3 Wireless LAN System

1.3.1 Peer-to-Peer Configuration

A Peer-to-Peer wireless LAN is a group of computers, each equipped with one Wireless LAN

card, connected as an independent wireless LAN. Computers in a specific 802.11 Ad-Hoc

wireless LAN must be configured at the same radio channel. 802.11 Ad-Hoc wireless LAN is

applicable to a departmental scale for a branch or SOHO operation.
