vi InstantWave High Rate Access Point

Introduction

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

networking product’s family. 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 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.

InstantWave High Rate Family

The InstantWave 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 Point (NWH660, NWH650)

• 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:

• A RS-232 cable

• An Ethernet drop (UTP)

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

necessary)

Cabling

Connecting the 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.

InstantWave High Rate Access Point 1

Glossary

Group ID/BSSID

A Group ID (the 802.11 standard uses the term BSSID) is the ID of a wireless cell.

A wireless cell is usually made up of stations in an area that the radio signal can

comfortably cover. In other words, any wireless station in the cell can

communicate with any other within reach of the radio signal.

Domain Name/ESSID

A “Domain” is most commonly used to refer to a group of computers whose

hostnames share a common suffix. The domain is usually defined by the network

administrator as a segment/subnet of a large network and may be made up of

overlapping wireless cells. Wireless nodes can roam freely within the same

domain without disconnecting from the network.

Roaming

The convenience of a mobile PC is the ability to move freely. The concept is

similar to that of a cellular phone moving from one base station to another.

InstantWave High Rate offers built-in high performance and seamless roaming

capabilities.

Regulatory Domain

InstantWave High Rate products use the unlicensed ISM (Industrial, Scientific,

Medical) band to communicate through radio waves. Different countries offer

different radio frequencies to be used as the ISM band. There are four frequency

bands defined by 802.11: Japan (2.471GHz – 2.497 GHz), USA, Extended Japan,

Canada, and Europe (2.4 GHz – 2.4835 GHz), Spain (2.445 GHz – 2.475 GHz),

and France (2.4465 GHz – 2.4835 GHz). To use InstantWave High Rate in a

country not listed above, check with your government’s regulating body to find the

correct frequency band to use. All InstantWave High Rate products are supplied

preset to the country of sale’s frequency band.

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 9, 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 12, 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.

InstantWave High Rate Access Point 3

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 Station-1 and Station-2, the radio transmission distance is

effectively doubled since Station-1 can talk to Station-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.
