LANCOM 3550 Wireless

Preface

Preface

Thank you for placing your trust in this LANCOM product.

The combination of UMTS/HSDPA, WLAN, DSL and VPN opens up a completely

new range of possibilities in enterprise connectivity—for example, mobile

conferen-ce rooms that are connected via UMTS/HSDPA and offer Internet

access over WLAN or access to the company network via VPN.

As a back-up connection for site coupling, UMTS/HSDPA is cheaper and faster

than the conventional alternative, ISDN. Furthermore, it is significantly less

prone tofailure as there are no cables which are at risk from construction

works. Using VRRP with the LANCOM 3550 Wireless offers fully vendor-inde-

pendent high availa-bility and a completely transparent, automatic switch of

media in the event of backup.

Apart from that, UMTS/HSDPA is able to bridge the “last mile” for customers

who do not have access to an equivalent broadband connection. The UMTS/

HSDPA card is simply operated in the CardBus expansion slot of the LANCOM

3550 Wireless. The device automatically switches Internet access between

HSDPA, UMTS andGPRS depending on availability.

Security settings

For a carefree use of your device, we recommend to carry out all security set-

tings (e.g. Firewall, encryption, access protection, charge lock), which are not

already activated at the time of purchase of your device. The LANconfig wizard

’Check Security Settings’ will support you accomplishing this.Further informa-

tion regarding this topic can be found in chapter 'Security settings'.We ask

you additionally to inform you about technical developments and actual hints

to your product on our Web page www.lancom-systems.com, and to down-

load new software versions if necessary.

User manual and reference manual

The documentation of your device consists of three parts: the installation

guide, the user manual and the reference manual.

You are now reading the user manual. It contains all information you need to

start your device. It also contains the most important technical specification

for the device.

The reference manual can be found on the CD as an Acrobat (PDF) document.

It is designed as a supplement to the user manual and goes into detail on top-

ics that apply to a variety of devices. These include for example:

Chapter 1: Introduction

1Introduction

1.1 What is a Wireless LAN?

The following sections describe the functionality of wireless networks

in general. The functions supported by your device are listed in the

table 'What can your LANCOM Router do?'. Detailed information on

Wireless LANs can be found in the LCOS reference manual.

A Wireless LAN connects single terminals (e.g. PCs or notebooks) to a local

network (also LAN – Local Area Network). In contrast to a conventional LAN,

communication takes place via radio links rather than via network cables. This

is the reason why a Wireless LAN is also called a Wireless Local Area Network

(WLAN).

All functions of a cable-bound network are also available in a Wireless LAN:

access to files, servers, printers etc. is as possible as the connection of individ-

ual stations to an internal mail system or to the Internet access.

The advantages of Wireless LANs are obvious: notebooks and PCs can be set

up just where they are needed. Due to Wireless LANs, problems with missing

connections or structural alterations belong to the past.

Apart from that, wireless LANs can also be used for connections over longer

distances. Expensive leased lines and the associated construction measures

can be spared.

1.1.1 Which hardware to use?

Each station of the Wireless LAN needs access to the Wireless LAN in the form

of a wireless interface. Devices which have no built-in wireless interface can

be upgraded with a supplement card or an adapter.

LANCOM Systems offers wireless adapters by its AirLancer product

line. An AirLancer wireless adapter enables a device (e.g. PC or note-

book) for access to the Wireless LAN.

1.1.2 Operation modes of Wireless LANs and base stations

Wireless LAN technology and base stations in Wireless LANs are used in the

following operation modes:

Simple direct connections between terminals without base station (ad-

hoc mode)

LANCOM 3550 Wireless

Chapter 1: Introduction

Larger Wireless LANs, connection to LANs with one or more base stations

(infrastructure network)

Setting-up of an Internet access

Connecting two LANs via a direct radio link (point-to-point mode)

Connecting of devices with Ethernet interface via base stations (client

mode)

Extending an existing Ethernet network with WLAN (bridge mode)

Relay function for connecting networks via multiple access points.

1.2 The advantages of the UMTS/HSPDA solution

The combination of UMTS/HSPDA, WLAN, DSL and VPN opens up a com-

pletely new range of possibilities in enterprise connectivity—for example,

mobile conference rooms that are connected via UMTS/HSPDA and offer Inter-

net access over WLAN or access to the company network via VPN. As a back-

up connection for site coupling, UMTS/HSPDA is cheaper and/or faster than

the conventional alternatives, ISDN and Analog. Furthermore, it is signifi-

cantly less prone to failure as there are no cables which are at risk from con-

struction works. Apart from that, UMTS/HSPDA is able to bridge the “last

mile” for customers who do not have access to an equivalent broad-band

connection.

The UMTS/HSPDA card is simply operated in the CardBus expansion slot of the

appropriate LANCOM devices. The device automatically switches Internet

access between UMTS/HSPDA and GPRS depending on availability.

1.2.1 “Last mile“ via UMTS/HSPDA

The Internet connection over UMTS/HSPDA is recommendable wherever a

broadband Internet connection is not available. When accessing the Internet

with UMTS/HSPDA you can currently reach significant higher downstream

rates than with an ISDN connection.
