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.
