and off at any time, even when the device is hibernating.

•

Press the “WLAN” button on the FRITZ!Box briefly

or

•

Switch on the wireless LAN radio network using a con-

nected telephone

Extending a Wireless LAN Network

The range of a wireless radio network is not fixed. It depends

on

•

the wireless devices you are using for your wireless LAN

connections

•

interference in the vicinity of your wireless radio network

•

the structural conditions where you operate the wireless

radio network

•

the number of wireless devices in the vicinity of your

FRITZ!Box that work in the same frequency range

You can extend the range of your wireless radio network with

a wireless LAN repeater.

Or you can set up a second FRITZ!Box as a wireless LAN re-

peater.

Extending a Wireless Radio Network with a Wireless LAN

Repeater

You can extend your wireless radio network with a wireless

LAN repeater. In combination with the FRITZ!Box the AVM

FRITZ!WLAN Repeater is especially suitable. All models of the

FRITZ!WLAN Repeater series can be integrated into your wire-

less radio network and your home network by WPS Quick Con-

nection. Find out more in the Internet at:

Using an Existing FRITZ!Box as a Repeater

You can extend the wireless LAN radio network of your

FRITZ!Box with an additional FRITZ!Box you already have. To

extend your wireless LAN, configure the repeater function in

this device.

You can configure a FRITZ!Box as a repeater by working

through the following steps:

1.

Open the FRITZ!Box user interface; see

page 25

.

2.

Enable the advanced view.

3.

Select the “WLAN / Repeater” menu and follow the in-

structions displayed on the screen.

In the Help of the FRITZ!Box user interface you can find de-

tailed instructions.

Wireless LAN—Getting Technical

A wireless LAN is based on standards defined by the Institute

of Electrical and Electronic Engineers (IEEE). These standards

describe, for instance, the transmission speeds, encryption

methods and frequencies used in a wireless LAN network.

Data Throughput

The FRITZ!Box supports your choice of the standards

IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n and

IEEE 802.11ac. Wirelsess devices based on one or more of

the standards listed can be used for wireless LAN connec-

tions with the FRITZ!Box.

The standards are intended for different frequency bands.

Wireless LAN—Getting Technical

IEEE 802.11a

Because this standard works exclusively in the seldom used

5-GHz range, it offers the opportunity to transmit data rela-

tively free of interference from external influences. Wireless

devices that support 802.11a are much less common than

devices that work in accordance with the 802.11b/g stan-

dard.

IEEE 802.11b

With a maximum throughput rate of 11 Mbit/s, this is the old-

est wireless standard. Older wireless devices of the first gen-

eration can communicate with the FRITZ!Box using 802.11b.

However, if the wireless device supports newer standards

such as 802.11g, the latest standard should be used.

IEEE 802.11g

In this wireless LAN standard data are transmitted in the 2.4-

GHz range at a maximum gross throughput of 54 Mbit/s. This

standard is compatible with a wide range of wireless devices.

However, due to heavy use of the 2.4-GHz range, interference

is more common than in the less-used 5-GHz range.

IEEE 802.11n

This standard allows for high throughput rates and ranges.

The FRITZ!Box supports 802.11n in the 2.4-GHz frequency

band, and parallel in the 5-GHz frequency band. Modulation

processes and antenna techniques like MIMO (Multiple In-

put, Multiple Output) use whichever frequency band is avail-

able more effectively than the older standards.

Thanks to compatibility with the 802.11g standard, you can

also continue to use older wireless devices.

The use of the 802.11n standard—and thus the availability

of higher throughput rates—is possible only if the wireless

LAN connection is secured using the WPA2 security mecha-

nism (AES-CCMP).

IEEE 802.11ac

This standard provides for transmission rates in the gigabit

range. The high throughput rates are achieved using wider

wireless LAN channels, deeper modulation and more MIMO

streams. Channels can be 20, 40, or 80 MHz wide. Modula-

tions of up to 8 bit/256QAM are applied. The standard uses

only the 5-GHz range, which reduces interference with other

users.

This standard is compatible with the 802.11a and 802.11n

standards, which means it can be used with older wireless

devices.

The FRITZ!Box 6490 Cable has a second access point respon-

sible for the 2.4-GHz range. This allows wireless devices com-

patible with the 802.11b/g/n to be used as well.

Setting the Right Standard in the FRITZ!Box

The throughput rate that can be achieved in your wireless ra-

dio network depends on the wireless standards used by the

integrated wireless devices. These wireless standards must

also be set in the FRITZ!Box. Proceed as follows to check

which wireless LAN standards are set and change them if

needed:

1.

Open the FRITZ!Box user interface; see

page 25

.

2.

Enable the advanced view.

3.

Open “WLAN / Radio Channel” and select which wireless

LAN standards should be used for both frequency

bands.

Note the following for the configuration of this setting:

•

Your FRITZ!Box 6490 Cable can make two wireless net-

works available simultaneously for data transmission.

One of the wireless radio networks works in the 2.4-GHz

frequency band, and the other in the 5-GHz frequency

The use of the 802.11ac standard—and thus the availability

of higher throughput rates—is possible only if the wireless

LAN connection is secured using the WPA2 security mecha-

nism (AES-CCMP).

band. This means the FRITZ!Box can be implemented as

an especially flexible wireless access point for the vari-

ous wireless devices and applications in your network.

•

Set the standards of the two wireless radio networks in

the FRITZ!Box such that they are compatible with all of

the wireless LAN devices used in the wireless network.

Make a note of which standards the wireless devices in your

network are compatible with and then adjust the FRITZ!Box

settings according to the following information:

11n, 11g

In your radio network there are wireless LAN devices that are

compatible with one or both of the following standards:

•

802.11n

•

802.11g

In this case set the wireless LAN standard for the 2.4-GHz fre-

quency band to: 802.11n+g

11g, 11b

In your radio network there are wireless LAN devices that are

compatible with one or both of the following standards:

•

802.11g

•

802.11b

In this case set the wireless LAN standard for the 2.4-GHz fre-

quency band to: 802.11b+g

11n, 11g, 11b

In your radio network there are wireless LAN devices that are

compatible with one or all of the following standards:

•

802.11n

•

802.11g

•

802.11b

In this case set the wireless LAN standard for the 2.4-GHz fre-

quency band to: 802.11n+b+g.
