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- independent 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.

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 individual 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 notebook) 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)
9

Chapter 1: Introduction

1.2 The advantages of the UMTS/HSPDA solution
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.
The combination of UMTS/HSPDA, WLAN, DSL and VPN opens up a completely new range of possibilities in enterprise connectivity—for example,
mobile conference rooms that are connected via UMTS/HSPDA and offer Internet access over WLAN or access to the company network via VPN. As a backup connection for site coupling, UMTS/HSPDA is cheaper and/or faster than
the conventional alternatives, ISDN and Analog. Furthermore, it is significantly less prone to failure as there are no cables which are at risk from construction 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.
10
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.
Internet
LANCOM 3550 Wireless
Chapter 1: Introduction
Internet connection over UMTS/HSPDA
For a regular Internet connection over UMTS/HSPDA, various net providers
offer so called “homezone“ tariffs. With this tariff the data transfer within the
homezone radio cell is usually far below the costs of the usual mobile tariffs
where the data card is used in multiple radio cells.
A special application is the use of a WLAN Access Point with UMTS/
HSPDA connection and LANCOM UMTS/VPN Option as a HotSpot in
places without Internet via cable.
EN
1.2.2 Mobile conference room
The modern business world requires ever increasing mobility from a growing
number of employees. That means that a constant access to e-mails, Internet
or to servers at headquarters is becoming more and more important.
A WLAN access point with UMTS/HSPDA connection provides the required
flexibility for people who often work in different places. Nearly every modern
notebook has a WLAN interface; the only thing missing for mobile Internet or
VPN access is a WAN interface. With the wireless Internet access over UMTS/
HSPDA or GPRS, mobile working areas can be created very easily.

Mobile WLAN, e.g. for a „mobile
conference room“.
Internet connection over UMTS/HSPDA
Internet
VPN connection to headquarters
For a group of staff members, who e.g. often work together on projects at a
customer’s location, a so-called mobile conference room can be established.
The access point then only has to be configured once by the administrator; the
staff members on location simply have to supply the device with power and
slot in the data card. With an appropriate configuration the router automatically builds up a connection to the Internet. The result is that all notebooks
with a compatible passphrase in the WLAN configuration can directly access
the Internet. As long as the router has a VPN connection to headquarters, the
field staff can also access all of the services in the network of headquarters
(fileserver, mailserver, data bases) from the mobile office.
12
With the LANCOM UMTS/VPN Option the VPN support with five con-
nection channels is automatically activated. Further information to
the configuration can be found in the LCOS reference manual.
1.2.3 UMTS/HSPDA Backup
The high availability of data lines e. g. between branch offices and headquarters in large company networks are in the majority of cases established over
backup solutions with ISDN or analog. The standard Internet connection is
then provided e. g. over a DSL connection, and an ISDN or analog line is used
as a backup line in the case the DSL line breaks down.
Brach office with VPN over DSL
and backup over UMTS/HSPDA
As an alternative to the ISDN or analog backup method, a UMTS/HSPDA connection can assure the availability of the data connection. If the connection to
the Internet is established by a router with LANCOM UMTS/VPN Option, the
UMTS/HSPDA connection can directly replace the DSL connection in the case
of a breakdown. The advantages of the UMTS/HSPDA backup solution compared to the ISDN/analog option:
Faster than ISDN/analog: the data rate with UMTS/HSPDA is considerably
faster.
Safer than ISDN or analog: if a physical damage of the DSL line is the rea-
son for the breakdown, the ISDN/analog line usually breaks down as well
because both use the same physical line.
Cheaper than ISDN: the monthly charges for an UMTS/HSPDA account
depend upon the tariff well under the charges for an ISDN account. Compared to the short time of breakdown of a DSL connection, the higher
connection tariffs for the UMTS/HSPDA are not relevant.
Adding the UMTS/HSPDA backup to existing installations is often simply an
issue of adding devices with LANCOM UMTS/VPN Option to existing LANCOM
devices. In complicated scenarios an existing ISDN backup in a VPN router can
be extended by the UMTS/HSPDA backup in a second device. In this case, the
routers will exchange the information about accessible routes using the
“Routing Information Protocol“ (RIP).
A sophisticated backup system for protection against router hardware failure
can be implemented by using VRRP. Two or more routers are installed in a network, one of which can replace the other in case of device failure. In addition
to normal VRRP, LANCOM devices can link the backup event triggering function to the availability of a data connection. With this additional feature,

Chapter 1: Introduction
LANCOM devices with more than one WAN interface (e.g. DSL and UMTS/
HSPDA interface) can be implemented flexibly in backup solutions. The
backup event is triggered for example, when the default route is no longer
available via the DSL interface. The device's UMTS/HSPDA interface can take
its place further along in the backup chain should the the backup router also
fail.

2.5 Hardware installation
The installation of the LANCOM 3550 Wireless base station takes place in the
following steps:
햲 Mounting of ferrite corres – For operating the device it is necessary to
fix the included ferrite cores with the LAN cable, the WAN cable and with
the power adapter cable.
LANCOM 3550 Wireless
Chapter 2: Installation
To do so, pull the cable twice through the ferrite core so that a bow around
the core results. (see illustrations).
The ferrite corres should be fixed near the plugs (closer than 10 cm).
햳 Antennas – Screw on the both included diversity antennas at the back of
the LANCOM 3550 Wireless base station.
햴 LAN – You can first connect the LANCOM 3550 Wireless base station to
your LAN. For that purpose, plug the included network cable (green plugs)
into the LAN connector of the device and the other end into a free network connecting socket of your local network (resp. into a free socket of
a hub/switch). Alternatively, you can also connect a single PC. In this case,
turn the node/hub switch on 'hub' ( ).
The LAN connector identifies automatically the transfer rate (10/100 Mbp)
of the connected network device (autosensing).
For information about the installation of PoE see the info box 'Powerover-Ethernet – elegant power supply through the LAN wiring'.
햵 DSL or cable modem – use the WAN connector cable (deep blue plugs)
and connect your DSL or cable modem to the WAN connector .
햶 Connect to power – Connect socket of the unit to a power supply
using the included power adapter.
Use the supplied power supply unit only! Using an unsuitable power
supply unit may cause damage or injury.
햷 Operational? – After a short device self-test the Power LED will be per-
manently lit green resp. will blink alternately red and green as long as no
configuration password has been given.

Power-over-Ethernet – elegant power supply through the LAN wiring
LANCOM 3550 Wireless base stations are prepared for the PoE power supply (Power-overEthernet). PoE-enabled network devices can be comfortably supplied with power feeding
through the LAN wiring. A separate external power supply for each base station is unnecessary, which reduces the the installation complexity considerably.
EN
Installation of single devices
The power feeding into the LAN happens at a
central position, either via a PoE power injec-
Hub/Switch
tor, or via a so-called powerhub/powerswitch.
For the LAN wiring is to note that all 8 wires
Power Injector
must be available by the cabling. PoE feeds

The PoE supply works only in such network segments, in which exclusively PoE-capable
devices are operating. The protection of network devices without PoE support is guaranteed
by an intelligent mechanism, that tests the network segment for devices without PoE support
before starting the PoE power feeding. The power is only switched onto the segment if only
devices with PoE support were detected.
LANCOM 3550 Wireless supports the proprietary PoE solution by PowerDsine. It is not fully
compatible to the finshed standard 802.3af. Although, most of the currently on the marked
available Power Hubs and Power Injectors are compatible to the pre-standard of 802.3af. The
PowerDsine Hubs of the 6024, 6012 and 6006 series have been tested by LANCOM Systems
for full interoparability. For damages caused by inadmissible devices no warranty may be
claimed.
