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 WLAN USB dongle 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 WLAN USB dongle on
various devices with USB port. It is able to communicate with other IEEE 802.11b compatible products to create a
wireless LAN in your office or home.

Direct Sequence Spread Spectrum (DSSS) technology provides robust, interference-resistant and secure
wireless connection.
Wireless connection without the hassles and cost of cabling.
Greater flexibility to locate or move networked PC’s.
1.2 Applications
Home networking for device sharing - Remote access to corporate network information email, file transfer
and terminal emulation.
Frequently changing environments - Retailers, manufacturers and banks that frequently rearrange the
workplace and change location.
SOHO (Small Office and Home Office) users - SOHO users need easy and quick installation of a small
computer network functions.
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
1.3.1 802.11 Ad-Hoc Configuration
An 802.11 Ad-Hoc wireless LAN is a group of computers, each equipped with one WLAN USB dongle, 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.
