Introduction

Your ZoomAir AP11™

™™

™Wireless Access Point provides ease and

flexibility in extending a wired or wireless Local Area Network

(LAN) for use with wireless clients. This Introduction includes

the following:

•A list of the components included with the unit and other

items you will need.

•Details of the ZoomAir AP11 and its feature set as a

wireless access point.

•An implementation plan or “road map” that guides you

through several phases of installation and setup of the

ZoomAir AP11 and its integration into your LAN.

Tip: Be sure to read the road map. It will greatly simplify your

understanding of the ZoomAir AP11 installation process.

You can get up and running by mastering basic operations,

and tackle more complex concepts and operations as your

future needs dictate.

Overview

The ZoomAir AP11 is a hardware access point for linking IEEE

802.11b DSSS-compliant wireless clients to each other and to a

wired LAN. Laptop computers and desktop computers equipped

with their own ZoomAir Wireless LAN Cards can communicate

with each other, and with computers, printers, and other devices

on your wired LAN. See the following illustration.

8 Installation Guide: ZOOMAIR AP11

With an access point, you gain tremendous flexibility in planning

and implementing your wireless LAN. For example, one of your

sales representatives can come into the office with a laptop

computer and link instantly to the network (with built-in security

provisions). From the laptop, the sales representative can print to

networked printers and copy files to and from other computers on

the network. Also, desktop computers equipped with ZoomAir PC

Cards can be located just about anywhere in an office without

having to be wired to a hub. Changing offices requires no rewiring

and no changing of settings on the computer or central servers.

Difficult installations suddenly become easy!

Security

The ZoomAir PC Card included with the ZoomAir AP11 is IEEE

802.11b-compatible, using Direct Sequence Spread Spectrum

(DSSS) technology. Spread spectrum signals are inherently difficult

for unauthorized users to decode. Also, all wireless nodes on your

network must use a special Service Set Identifier (SSID) to be

recognized. Finally, Wired Equivalent Privacy (WEP) software

provides security that equals or exceeds that of wired networks.

Installing a basic access point usually involves plugging in the

ZoomAir PC Card and its antenna, making two connections (data

and power), and turning on the unit. See the following illustration.

Introduction 9

If ZoomAir Wireless LAN cards are installed at the same time on

client computers, most users will not even need to reconfigure their network.

The on-board configuration software (i.e. WebManage) can be run

from nearly any computer using a Web-compatible browser

(Netscape Navigator 4.0 or later or Internet Explorer (IE) 4.0 or

later). Administration of the LAN is simplified, thanks to DHCP

(Dynamic Host Configuration Protocol). DHCP dynamically

assigns IP addresses to client computers.
