InstantWave High Rate 11Mbps Access Point 1

Introduction

Congratulations on choosing one of NDC’s InstantWave High Rate wireless

networking products. InstantWave High Rate was one of the first IEEE 802.11b

wireless standard compliant products in the industry and was designed to maximize

the convenience of networking. You will find InstantWave High Rate products

very easy to setup and use.

The User’s Guide gives comprehensive instructions on installing and using the

InstantWave NWH650 High Rate Access Point (AP). The AP provides a

transparent bridged connection between a wired network and a wireless network

and allows your wireless stations to communicate with devices attached to your

wired network. It manages the flow of data packets from the wired LAN to the

wireless LAN, and vice versa. The Access Point Management System (APMS)

performs wireless network configuration management and diagnostic functions.

InstantWave High Rate Family

The InstantWave NWH650 High Rate Access Point is part of a family of easy to

use high performance wireless communication products. The family products

include:

•InstantWave High Rate Access Points (NWH650, NWH660)

•InstantWave High Rate PCI Card (NWH630)

•InstantWave High Rate PC Card (NWH610)

System Requirements

System requirements to install and operate the InstantWave High Rate Access

Point are:

•One PC

•One 802.11b compliant card

•An Ethernet drop (UTP)

•An RS-232 cable (only used when configuration of the AP’s network

properties is necessary)

•A PC (only used when configuration of the AP’s network properties is

necessary)

Cabling

Connecting the Access Point (AP) to an Ethernet network requires an Unshielded

Twisted-Pair cable. The AP fits into the network just as any other node would do.

An LED will light to indicate a connection. The cable length should follow

Ethernet standards in each case.

How to Use this Guide

InstantWave High Rate is extremely versatile in providing varying levels of

network management. For Small Office/Home Office users, setup and

configuration is a quick, four-step process. The Access Point Hardware

Installation section, on page 8, provides simple instructions to get your network up

and running within minutes. Go to the Access Point Hardware Installation section

if your network will meet the following criteria:

•You will accept all default values

•Your network will have only one Access Point

The AP COMFig tool, see page 11, permits AP configuration from a PC via a

COM port connection. The program enables the user to change the default Access

Point IP configuration settings before introducing a new AP to an already

established wireless network.

Before using the setup tool, you should read through the next section ‘Planning

Your Network’, in order to get the best possible performance from your

InstantWave High Rate wireless network.

Planning Your Network

Infrastructure Network Types

An Infrastructure network is formed by several stations and one or more Access

Points (APs), with the stations within a set distance from the AP. Figure 1 depicts

a typical Infrastructure network topology.

There are three infrastructure network setups that are commonly used. It is a good

idea to understand the possible network setups and configuration requirements

before planning your wireless network.

Type 1. The simplest wireless infrastructure network is composed of one

Access Point (AP) and a few wireless Stations communicating via

radio waves (Figure 1). This setup enables mobile stations to

communicate with each other. The main benefit of this type of

network is to extend the range of the network. If an AP is placed

between the stations, the radio transmission distance is effectively

doubled since Wireless Computer-1 can talk to Wireless Computer-2

through the AP. The drawback of this configuration is that the

effective bandwidth is halved since all communication is relayed by

the AP.

Figure 1. Simple Wireless Infrastructure Network

Type 2. The next simplest wireless network is very similar to the Type 1

network. This time the AP is connected to a wired Ethernet network

as a node. In this configuration the AP is effectively performing as a

bridge between the wired Ethernet and the wireless networks (Figure

2).

Wireless users have the same access to the network resources as they

would have if they were wired. This type of network is usually used

to extend an existing network into a difficult to wire or a roaming

environment.

Type 3. The third type of network is composed of multiple APs and multiple

Stations (Figure 3).

Figure 3. Multiple AP Network

The reasons for having multiple APs installed are:

1. To increase bandwidth in order to boost overall network performance

2. To extend the coverage range

Any other type of configuration is usually a mix of these commonly used types.
