• 802.11b versus 802.11a Networks

• Installation and Initialization

Wireless Networking Concepts

The AP-3 provides wireless access to network infrastructures. As wireless

clients move from one coverage cell to another, AP-3 units automatically

allow client roaming within the same subnet.

To determine the best location for the Base Station units, it is

recommended that you conduct a Site Survey before placing the devices

in their final locations. For information about how to conduct a Site

Survey, contact your local reseller.

Introduction

Avaya Wireless AP-3 User’s Giode 1-1

Wireless Networking Concepts

1-2 Avaya Wireless AP-3 User’s Guide

Before the AP-3 unit can be configured for your specific networking

requirements, it must first be initialized so that you can recognize it once

it is located in your network. Initialization consists of setting

• a static IP address and

• the appropriate IP mask.

Figure 3-2:Standalone wireless network access infrastructure

Management and Monitoring Capabilities

Avaya Wireless AP-3 User’s Guide 1-3

The network administrator can configure each unit according to the

requirements for the network. The Access Point 3 (AP-3) functions as a

wireless network access point to data networks. AP-3 networks provide:

• Seamless client roaming

• Easy installation and operation

• Over-the-air encryption of data

• High speed network links

To be fully operational, the AP-3 needs at least one Avaya Wireless

PC Card.

Note: PC Cards are not included with your kit and must be ordered as

separate items. Note that you cannot insert an Avaya Wireless

802.11a/b Card into the AP-3.

Management and Monitoring Capabilities

To configure the AP-3 for your needs, set your specific network, wireless

interface, and bridge parameters. The HTTP (web browser) Interface

provides easy configuration and management.

Wireless clients (computers connected to your network through a radio

PC Card) use configuration software for network access. Once connected,

users can roam from one coverage cell to another while maintaining their

connection.

Management and Monitoring Capabilities

1-4 Avaya Wireless AP-3 User’s Guide

There are three management and monitoring interfaces available to the

network administrator to configure and manage the AP-3 device(s) in the

network:

• HTTP Interface

• Command Line Interface

• SNMP configuration capabilities

HTTP Interface

The HTTP Interface (Web browser Interface) provides easy access to

configuration settings and network statistics from any computer in the

network. Use the HTTP Interface through your LAN (switch, hub, etc.),

through the Internet, or with a “crossover” Ethernet cable connected

directly to your computer’s Ethernet Port.

Command Line Interface

The Command Line Interface (CLI) represents a set of keyboard

commands and parameters used for configuring and managing the AP-3.
