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 TWL-A11 is designed to meet the mobility, performance, security, interoperability, management, reliability
requirements of IEEE 802.11b high data rate standard and IEEE 802.3 Ethernet 10 Base-T standard. When
installed, TWL-A11 can communicate with other IEEE 802.11b and IEEE 802.3 compatible products to create a
wireless network in your office or home.

1.1 Features

 Compliant with IEEE 802.11b standard.
 Automatic data rate fallback under noisy environment (11/5.5/2/1Mbps).
 Interoperable with IEEE 802.11b and IEEE 802.3 compliant equipment.
 Supports full mobility and seamless roaming from cell to cell.
 Local, remote and automatic configuration.
 Easy client management with utility software under Windows 95/98/ME/2000/XP.
 Desktop and wall/ceiling mount.
 Up to 300m operating range (environment dependent).
 Supports point-to-point and point-to-multipoint access.
 Direct Sequence Spread Spectrum (DSSS) technology provides robust, interference-resistant and secure

wireless connection.

 Supports bridging function.
 Support TCP/IP, NETBEUI, and DHCP client.
 Internal/external antenna versions available.

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.
