Wireless local area network (WLAN)

In a wireless local area network (WLAN), PCs are linked without wires or cables. The PCs

have to be equipped with a wireless local area network adapter (WLAN adapter), for

example a Gigaset USB Adapter 108.

We generally differentiate between two types of wireless network:

u

Infrastructure mode

u

Ad-hoc mode

Infrastructure mode

Infrastructure mode connects wireless and wired networks with one another. In addi-

tion to the mobile stations, infrastructure mode needs an access point such as the

Gigaset SX763 WLAN dsl. In infrastructure mode, the stations in the network always

communicate via this access point. The access point sets up the wireless network on a

permanent basis. Each station that wants to be part of the wireless network must first

register with the access point before it can exchange data.

The access point establishes the connection between the mobile stations of a wireless

network and a wired LAN (Ethernet) or the Internet. In this case this is described as the

device's router functionality. The router sends data packets that are not addressed to sta-

tions within the network "outside" and forwards data packets originating from "outside"

to the appropriate station within the network.

You can use the Gigaset SX763 WLAN dsl to connect

u

wirelessly networked PCs to the Internet and

u

wirelessly networked PCs to an Ethernet network.

Infrastructure mode is the default configuration for the Gigaset SX763 WLAN dsl.

Ad-hoc mode

An ad-hoc network is a wireless network that has been configured without an access

point or a router. The mobile network components that communicate with each other

directly and wirelessly form the network on an "ad-hoc" basis, i.e. as and when required.

All the stations in the network have the same rights. Ad-hoc networks are used wher-

ever communications networks have to be set up quickly and there is no existing net-

work infrastructure, and where the participants are on the move.

Linking wireless networks with the Internet

The Gigaset SX763 WLAN dsl has an ADSL interface that permits all stations within its

local area network to access the Internet simultaneously. To be able to use this function-

ality, you need a DSL connection obtainable from an Internet service provider. Find out

whether your service provider supports parallel access by several PCs.

Linking a wireless network to an Ethernet

Wireless local area networks can work easily together with existing Ethernet networks.

If you wish to connect mobile stations to an existing wired network, you must group

together all mobile stations into a wireless local area network in infrastructure mode.

The Gigaset SX763 WLAN dsl has four Ethernet interfaces (LAN ports). Up to four PCs

can be connected directly to these LAN ports.

All PCs can access the Internet via the Gigaset SX763 WLAN dsl.

Please remember:

You can also connect an Ethernet router or switch to a LAN port to access a larger

Ethernet. If you want to link the Gigaset WLAN network to an existing network, a large

number of settings have to be applied. Therefore we cannot provide a general exam-

ple for this use; the configuration depends greatly on the networks in question. We

advise having the configuration of such a network carried out by a specialist.

Extending the wireless network coverage with a repeater

Using the Gigaset WLAN Repeater, you can extend your wireless network's coverage. Set

it up within the range of your network. The repeater will now transmit data traffic into

its own wireless area. This technology allows you to set up wireless networks that cover

a much larger area than is possible with a single Gigaset SX763 WLAN dsl.

PCs to be connected in a wireless local area network via a repeater must be equipped

with an integrated wireless network adapter or you have to connect an external wireless

network adapter (e.g. a USB adapter).

Internet telephony and connecting analogue phones

The Gigaset SX763 WLAN dsl allows a combination of analogue fixed network teleph-

ony and

Internet telephony

(

VoIP

) over DSL for two analogue telephones and four other

wired or wireless VoIP telephones or SIP clients.

This provides you with the full benefits of both technologies. You can make use of the

low-cost call rates of Internet telephony without any additional equipment. In addition,

you have the option of using your analogue fixed network connection. The type of calls

that are cheaper for you will depend on what calls you make and when you make them,

and the rates offered by your service provider. The Gigaset SX763 WLAN dsl gives you

complete freedom of choice at any time.

You can choose whether to connect any two analogue phones, a fax machine or an

answering machine to the phone ports. You can configure these ports using the Gigaset

SX763 WLAN dsl.

The PABX of the Gigaset SX763 WLAN dsl allows you to connect wireless SIP phones

(WLAN handsets) and PCs with SIP clients (software for Internet telephony) as exten-

sions. You can use all functions of your PABX for Internet telephony also.

You will need the relevant access data for your VoIP provider to configure Internet

telephony.

Please remember:

You can only be reached via the Internet (VoIP) when an

active Internet connection

is established. You can still be called any time via the fixed network, however.
