Information for Canadian Users

The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective operation and safety requirements. The Industry Canada does not guarantee that the equipment will operate to a user's satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company's inside wiring associated with a single line individual service may be extended by means of a certified connector assembly. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

For their own protection, users should ensure that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Caution

Users should not attempt to make such connections themselves, but should contact the appropriate electrical inspection authority, or electrician, as appropriate.

Note

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the radio interference regulations of Industry.

This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.

If this equipment does cause harmful interference to radio/television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

1. Reorient or relocate the receiving antenna.

2. Increase the separation between the equipment and the receiver.

3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

4. Consult the dealer or an experienced radio/TV technician for help.

Notice 1

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Caution

1. To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons.

2. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter

Additional Information to OEM Integrators

ASDL modems, and similar equipment). The final end product must be labeled in a visible area with the following: Contains TX FCC ID: I88B620

IMPORTANT NOTE

1. In the event that these conditions can not be met (for example certain laptop configurations or colocation with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

2. To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be colocated or operating in conjunction with any other antenna or transmitter."

Preface

Congratulations on the purchase of your new ZyAIR!

About This User's Guide

A practical and comprehensive tool, this manual provides information about the ZyAIR Wireless LAN Utility. Familiarize yourself with the Syntax Conventions listed for better and faster understanding.

The ZyAIR Wireless LAN Utility is common to ZyAIR B-x20 Wireless LAN Adapter series, thus the model name shown in the screens may vary from what you actually purchased.

Wireless Network Basics

This chapter gives you an overview of what a wireless network is, its advantages and

applications.

1.1 Introduction

A wireless LAN (WLAN) provides a flexible data communication system that you can use to access various services (navigating the Internet, email, printer services, etc.) on the wired network without additional expensive network cabling infrastructure. In effect, a wireless LAN environment provides you the freedom to stay connected to the wired network while moving in the coverage area.

1.2 Benefits of a Wireless LAN

 Access to network services in areas otherwise hard or expensive to wire, such as historical

buildings, buildings with asbestos materials and classrooms.

 Doctors and nurses can access a complete patient’s profile on a handheld or notebook computer

upon entering a patient’s room.

 It allows flexible workgroups a lower total cost of ownership for networks that are frequently

reconfigured.

 Conference room users can access the network as they move from meeting to meeting- accessing

up-to-date information that facilitates the ability to communicate decisions “on the fly”.

 It provides campus-wide networking coverage, allowing enterprises the roaming capability to set

up easy-to-use wireless networks that transparently covers an entire campus.

1.3 Applications

Unlike wired networks, you can set up wireless networks in two different modes: infrastructure and ad-hoc. Set up your wireless network depending on your network needs. The following sections describe each network mode.

1.3.1 Ad-hoc

An ad-hoc network consists of two or more computers communicating with one another through the wireless network. No access points (APs) or existing wired networks are needed. An access point acts as a bridge between the wireless and wired networks

Figure 1-2 Ad-hoc Application Example 2

1.3.2 Infrastructure

When wireless clients wish to access and share resources on the wired network, they should use infrastructure mode. Wireless clients may move from one coverage area to another seamlessly without network interruption. This is called roaming.
