Registration Not Possible
6.4 Registration Not Possible
To configure the FRITZ!WLAN Repeater for the first time without
the WPS function, the WLAN adapter must be compatible with
the WPA/WPA2 encryption method. Check which kinds of en-
cryption your WLAN adapter supports and set WPA/WPA2 as the
encryption method on your WLAN adapter.
Possible Cause
The FRITZ!WLAN Repeater and your WLAN adapter cannot be
connected to each other via WPS.
Remedy
The WPS function on the FRITZ!WLAN Repeater can only be used
to connect with a WLAN access point. Therefore you have to
check whether the network name and the encryption of the
FRITZ!WLAN Repeater and of your WLAN access point are identi-
cal (factory settings). Then start the WPS function on your WLAN
access point and switch to the reception area of the
FRITZ!WLAN Repeater.
Possible Cause
A WLAN radio network in the vicinity of the FRITZ!WLAN Repeater
of your access point is causing interference.
Remedy
Test a different radio channel. If possible, configure your access
point so that it automatically searches for a suitable channel.
Possible Cause
The MAC address filter of the access point is enabled and the
FRITZ!WLAN Repeater is not entered as an exception in the MAC
address list of the access point.
Remedy
Enter the MAC address of the repeater as an exception in the
MAC address filter of the access point.
The FRITZ!WLAN Repeater cannot be registered at the access

Microsoft WLAN Service (WZC) Is Not Supported
FRITZ!WLAN Repeater N/G 23
6.5 Microsoft WLAN Service (WZC) Is Not Supported
6.6 No Higher Data Rates Available
Set the SSID to “visible” (announced).
For registration with the WPS function the SSID must be visible.
After successful registration you can hide the SSID of the access
point again.
The WLAN connection to the FRITZ!WLAN Repeater cannot be
established using the Microsoft WLAN Service (WZC) in
Windows XP with Service Pack 2.
Possible Cause
The required Microsoft patch for WPA2 (IEEE 802.11i) may not
be not installed.
Remedy
Install the current patch for Microsoft Windows XP with Service
Pack 2 from the web page
http://support.microsoft.com/kb/91702/EN-US or install Ser-
vice Pack 3.
Higher data rates in accordance with the WLAN standard
IEEE 802.11n are not available on one of the WLAN clients
connected to the FRITZ!WLAN Repeater (e.g., your notebook).
Possible Cause
The connection between the FRITZ!WLAN Repeater and the
WLAN base station or between the FRITZ!WLAN Repeater and the
WLAN client is not encrypted using WPA2. The use of the
IEEE 802.11n standard—and thus the availability of higher
throughput rates—is possible only if the WLAN connection is se-
cured using the WPA2 (AES-CCMP) security mechanism.
Remedy
Set the WLAN encryption of the FRITZ!WLAN Repeater and the
encryption of the WLAN base station to WPA2. It is also possible
to achieve the data throughput rates of the 802.11n standard if
all WLAN participants transmit wirelessly. Because of the securi-
ty risk associated with an open wireless network, we expressly
advise against using this option!

Interference During Audio Output
6.7 Interference During Audio Output
The audio output is overmodulated or the music sounds very
distorted.
Possible Cause
Headphones are connected directly to the 3.5-mm stereo jack.
This stereo jack is a non-variable line-out jack.
Remedy
Connect the FRITZ!WLAN Repeater to the line-in input of your re-
ceiver (e.g. the amplifier), or use the miniature FM transmitter of
the FRITZ!WLAN Repeater to send the audio signals directly to
an FM radio.
The radio signal is subject to interference; the transmission has
static.
Possible Cause
The transmission frequency you set overlaps with adjacent
transmitters.
Remedy
Change the FM transmission frequency. Please note the infor-
mation in the chapter “Connecting a Radio” from page 17.
Possible Cause
The FRITZ!WLAN Repeater is too far from the FM receiver, the sig-
nal is too weak.
Remedy
Reduce the distance between the FRITZ!WLAN Repeater and the
FM receiver.

2 More about WLAN
AVM and WLAN
WLAN (Wireless Local Area Network) is a radio technology that allows
networks access to the Internet to be provided without cable connec-
tions. This allows multiple users to share one wireless Internet connec-
tion.
2.1 Standards
The WLAN standards IEEE 802.11a, IEEE 802.11b,
IEEE 802.11g and IEEE 802.11n (on the basis of the pre-
liminary draft 2.0 of the standard) and IEEE 802.11i were
developed by the Institute of Electrical and Electronic En-
gineers (IEEE).
The standards IEEE 802.11a, IEEE 802.11b, IEEE 802.11g
and IEEE 802.11n define the transmission rate within a
wireless LAN. The IEEE 802.11i standard is a security stan-
dard.
Standards for the Throughput Rate
Data Throughput The FRITZ!WLAN Repeater supports the IEEE 802.11n wire-
less standard and is downward compatible to 802.11a, b
and g networks.
The standards are intended for different frequency bands.
The throughputs listed differentiate between gross and
net transmission rates. The net speed describes the trans-
mission rate of the user data.
The standard used in a given WLAN depends on the set-
tings of the WLAN access point.
Standard Frequency Band Gross Data Throughput up to Net Data Throughput up to
802.11a 5 GHz 54 Mbit/s 54 Mbit/s
802.11b 2.4 GHz 11 Mbit/s 5 Mbit/s
802.11g 2.4 GHz 54 Mbit/s 25 Mbit/s
802.11n 2.4 / 5 GHz 300 Mbit/s 100 Mbit/s
30
Standards for the Throughput Rate
Range The range within a WLAN is highly dependent on the fol-
lowing factors:
the WLAN adapter used
the structural conditions
the amount of radio traffic on the same frequency
band. Other WLAN networks, microwave ovens or
Bluetooth transmitters (mobile telephones) may be
active.
where the FRITZ!WLAN Repeater is positioned
The FRITZ!WLAN Repeater provides for optimum ex-
tension of your wireless network when it is posi-
tioned halfway between your access point and the
devices for which the wireless network is to be ex-
tended. The device should also be operated in a loca-
tion as central and free of obstruction as possible,
e.g. not in a closet, cabinet or below a radiator.
IEEE 802.11a This standard communicates with a maximum of
54 Mbit/s and works exclusively in the seldom used 5-
GHz range. This means it offers the opportunity to transmit
data relatively free of interference from external influenc-
es.
IEEE 802.11b With a maximum throughput rate of 11 Mbit/s, this is the
oldest standard for radio networks. Older WLAN access
points of the first generation can communicate with the
FRITZ!WLAN Repeater using 802.11b. However, if the
WLAN access point supports newer standards such as
802.11g, the latest standard should be used.
IEEE 802.11g This is currently the most common WLAN standard. It com-
municates with a maximum of 54 Mbit/s gross in the 2.4-
GHz frequency range (ISM) and guarantees broad compat-
ibility with many WLAN devices.
In order to communicate with each other, the
FRITZ!WLAN Repeater and the WLAN access point must
work in the same frequency band.
The Standard for Security
31
IEEE 802.11n This standard allows for high throughput rates and rang-
es. The FRITZ!WLAN Repeater supports 802.11n in the 2.4-
GHz frequency band, or, if desired, also in the 5-GHz fre-
quency band. Modulation processes and antenna tech-
niques like MIMO (Multiple Input, Multiple Output) use
the entire frequency band available more effectively than
the older standards.
The Standard for Security
IEEE 802.11i The WPA2 security mechanism is defined in the
IEEE 802.11i standard. WPA2 is an extension of the famil-
iar security mechanism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the
AES-CCMP encryption process.
The FRITZ!WLAN Repeater supports the AES encryption
procedure as part of the WPA2 mechanism, and the TKIP
encryption procedure as part of the WPA mechanism. This
means that the FRITZ!WLAN Repeater can be used in com-
bination with any WLAN adapters that also support WPA2
with AES or WPA with TKIP.
The use of the 802.11n standard—and thus the availabili-
ty of higher throughput rates—is possible only if the
WLAN connection is secured using the WPA2 security
mechanism (AES-CCMP).
Mechanism Encryption
WPA TKIP (Temporary Key Integrity Protocol)
WPA2 TKIP
AES-CCMP
based on the extremely secure AES (Ad-
vanced Encryption Standard) procedure.
CCM (Counter with CBC-MAC) defines how
the AES procedure is applied to WLAN
packets.
32
Security
2.2 Security
Security is of utmost importance within radio networks.
Therefore it is important that no unauthorized users can
register in a WLAN to use its Internet access or shared net-
work resources.
This is why the FRITZ!WLAN Repeater adopts the security
settings of your FRITZ!Box when it establishes a connec-
tion using WPS. For radio networks set up manually, these
security settings must be configured in the user interfaces
of the devices.
Encryption
The most important security setting is encryption. The
FRITZ!WLAN Repeater supports the security mechanisms
WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Ac-
cess) and WPA2 as follows:
As part of the WEP mechanism a static key is deter-
mined to serve for the encryption of the user data.
WLAN Radio Network Name (SSID)
In the factory settings of the FRITZ!WLAN Repeater a value
of “FRITZ!WLAN Repeater N/G” is preset as the default val-
ue of the SSID (Service Set Identifier). As soon as the ini-
tial configuration has been completed, the
FRITZ!WLAN Repeater automatically takes on the network
name of your WLAN base station. Depending on the WLAN
client used and how accessible it is, the network name of
the base station and the repeater will be listed once or
multiple times in the WLAN software. If you want to be
able to distinguish the FRITZ!WLAN Repeater from the
base station, you can change the network name of the
FRITZ!WLAN Repeater.
Radio signals can also be received outside of office or res-
idential spaces and abused for criminal purposes.
Frequency Ranges
33
2.3 Frequency Ranges
WLAN uses the frequency range around 2.4 GHz in the ISM
band or, alternatively, the frequency range at 5 GHz.
2.4-GHz Frequency
Band
In the 2.4-GHz frequency band WLAN works in the same
range as Bluetooth, microwave devices and various other
devices like some cordless telephones, radio-controlled
toys, garage-door openers and video bridges. This means
that interference may occur within WLANs operated in the
vicinity of such devices. Generally the only adverse effects
are to the transmission rate; aborted connections and da-
ta losses are rare.
WLAN in the 5-GHz frequency band is subject to less inter-
ference, as these radio frequencies are used much less of-
ten.
In the 2.4-GHz frequency range the European regulation
authorities have designated 13 channels for WLAN.
A channel can have a bandwidth of 20 MHz (throughput
up to 130 Mbit/s) or 40 MHz (throughput of up to
300 Mbit/s).
Channels located directly next to each other in the 2.4-
GHz band may overlap and result in mutual interference.
For instance, if several WLANs are operated close to each
other in the 2.4-GHz frequency range with a bandwidth of
20 MHz, a distance of at least five channels should be left
empty between each two channels used. This means that
if channel 1 is selected for one WLAN, the channels 6
through 13 can be selected for a second WLAN. This main-
tains the minimum distance between channels.
If your WLAN access point is equipped with an autochan-
nel function, you can automatically have it search for a
WLAN channel in your frequency range that is subject to as
little interference as possible.
In order to communicate with each other, the
FRITZ!WLAN Repeater and the WLAN access point must
work in the same frequency band.
34
Frequency Ranges
5-GHz Frequency
Band
The FRITZ!WLAN Repeater can operate in the 5-GHz fre-
quency band as an alternative. This frequency range is
used much less frequently than the most common 2.4-
GHz frequency range.
A prerequisite for use of the 5-GHz frequency band is that
all WLAN adapters in the network support this frequency
range in accordance with the IEEE 802.11a or
IEEE 8002.11n standard.
Bandwidth In both frequency ranges you can select between channel
bandwidths of 20 MHZ or 40 MHz (exception: channel 140
in the 5-GHz frequency band). The FRITZ!WLAN Repeater
initially attempts to select a channel with 40 MHz band-
width (throughput up to 300 Mbit/s). If this is not possible
due to interference or channels already being used by oth-
er WLANs in the vicinity, the FRITZ!WLAN Repeater auto-
matically switches over to a channel with 20 MHz band-
width. Greater bandwidth provides for higher data
throughput:
Increasing bandwidths also increases the probability of
interference by wireless networks in the vicinity. Large
bandwidths reduce the frequency range available to other
wireless networks in the vicinity.

Glossary
Glossary
ADSL abbreviation for Asymmetric Digital Subscriber Line
designates a fast kind of file transfer that works with stan-
dard copper cables and transports signals in both direc-
tions at different speeds (upstream at 640 Kbit/s and
downstream at up to 9 Mbit/s).
ADSL2 abbreviation for Asymmetric Digital Subscriber Line 2
ADSL2 (G.992.3) is a further development of the ADSL
norm G.992.1/G.992.2).
ADSL2 offers range much greater than did the first ADSL
generation, and is significantly more robust than ADSL, as
it can simply disable single carrier frequencies when they
produce interference. This feature allows ADSL2 to pre-
vent synchronization losses.
With a throughput rate of up to 12 Mbit/s downstream,
ADSL2 offers considerably greater bandwidth than ADSL.
ADSL2 is completely downward compatible, meaning that
terminal equipment compliant with ADSL can also be op-
erated on ADSL2 lines, although they cannot exploit the
advantages of ADSL2.
ADSL2+ abbreviation for extended bandwidth Asymmetric Digital
Subscriber Line 2
ADSL2+ (G.992.5) is a further development of the ADSL
norm (G.992.1/ G.992.2).
ADSL2+ offers a doubled frequency range used for down-
stream transmission, and thus double the maximum
bandwidth achievable for downstream to 24 Mbit/s.
ADSL2+ is completely downward compatible, meaning
that terminal equipment compliant with ADSL and ADSL2
can also be operated on ADSL2+ lines, although they can-
not exploit the advantages of ADSL2+.

Default Gateway see gateway
DHCP abbreviation for Dynamic Host Configuration Protocol
DHCP is a protocol for the dynamic negotiation of the op-
erating parameters for the TCP/IP protocol (TCP is a trans-
port protocol based on the Internet protocol).
The computers of a local IP network (DHCP clients) access
the DHCP server as part of their operating systems’ start
procedure.
The central administration of the TCP/IP operation param-
eters makes it possible to avoid address conflicts caused
by IP addresses accidentally assigned more than once.
DHCP Server The DHCP server assigns each client an IP address that is
has not yet been assigned at the present time. The DHCP
server also informs the client of the IP addresses of the
DNS server to be used and of the default gateway. In as-
signing the IP addresses the DHCP server selects from a
prescribed pool of IP addresses.
DNS abbreviation for Domain Name System
Domain Name Service takes care of determining the IP ad-
dress for a given domain name. This Domain Name Ser-
vice runs on every computer. It accepts the domain name
FRITZ!WLAN Repeater N/G 42
Glossary
entered by a user and inquires about the corresponding IP
address at a DNS server known to the service. If a DNS
server cannot answer the inquiry itself, it can inquire
about the IP address (DNS resolution) at other DNS serv-
ers.
If the Domain Name Service receives negative information
from the DNS server (domain name not known), it can
send inquiries to other DNS servers it knows or return a
corresponding error message to the user. If it receives the
desired IP address instead, the application can use the IP
address to retrieve the destination desired by the user.
This hierarchical system of DNS servers is known as the
Domain Name System. The addresses of the DNS servers
at which the Domain Name Service is to inquire by default
generally are handed over to the computer by the Internet
Service Provider automatically whenever a connection to
the Internet is established. In local networks addresses
can also be assigned via DHCP. Otherwise they must be
entered manually in the TCP/IP settings of the computer
by the user or the system administrator.
DSL Modem A DSL modem connects a computer to the Internet via the
DSL line. In contrast to the analog modem, a connection
via the DSL modem does not mean that the telephone line
is busy.
DSL Router A combination of a DSL modem and a router is called a
DSL router.
Dynamic DNS abbreviation for Dynamic Domain Name System
Dynamic DNS is a service which allows a computer always
to be reached under the same domain name despite con-
stantly changing IP addresses. This means that even pri-
vate users have an economical way of placing their own
Internet offers on their computer at home.
It works by transmitting the current IP address to a special
DDNS server each time the IP address changes. Except for
the few seconds between the cancellation of the old IP ad-
Glossary
FRITZ!WLAN Repeater N/G 43
dress and the notification of the new IP address, the com-
puter can always be reached at the selected domain
name.
Dynamic IP
Address
A dynamic IP address is an IP address valid only for the
duration of one Internet or network session.
Every computer participating in the Internet must have a
uniquely assigned public IP address. Since only a limited
number of such IP addresses is available, they must be
used sparingly. That is why most of the Internet partici-
pants who dial in to the Internet receive a dynamic IP ad-
dress. They are called dynamic because every participant
receives a new public address that has not been assigned
yet each time she or he dials in to the Internet.
By contrast, dynamic addresses are usually used in local
IP networks because they are easy to handle, and because
using them avoids incorrect IP address entries or uninten-
tional double assignments. The DHCP service is responsi-
ble for assigning unique dynamic IP addresses.
FAQ abbreviation for Frequently Asked Questions
FAQs are collections with answers to frequently asked
questions on a certain subject area.
Fixed IP address Fixed IP addresses are IP addresses which are permanent-
ly assigned to a computer or another device like a network
printer.
Assigning fixed IP addresses makes sense in cases where
a local network has a sufficiently large pool of IP address-
es available, or when a computer is always supposed to
be accessible at a certain address (such as a web server or
e-mail server).
Firewall A firewall protects a computer or local network against at-
tacks from the Internet.
Most firewalls work with packet filters, which merely
check the IP addresses and port numbers of incoming and
outgoing data packets and filter the packets according to
prescribed rules.
FRITZ!WLAN Repeater N/G 44
Glossary
Some firewalls also integrate additional concepts like IP
masquerading and NAT to decouple data traffic by distin-
guishing strictly between the internal and external net-
work.
Especially effective firewalls go even further, analyzing
and evaluating the contents of the packets and filtering
them according to prescribed rules. Such techniques may
also include a Stateful Packet Inspection Firewall, for in-
stance.
Firmware The firmware is saved in programmable components with-
in a device. Through the possibility of updating the firm-
ware by computer at any time, manufacturers enjoy great
flexibility in reacting to the demands of the operational
environment, integrating new functions requested by cus-
tomers, and eliminating errors discovered after produc-
tion.
FTP abbreviation for File Transfer Protocol
The File Transfer Protocol allows files to be exchanged be-
tween two computers operating in the Internet. Data ex-
change takes place via an FTP server and what is known as
an FTP client. The more convenient FTP clients are avail-
able as stand-alone software or are components of some
ISDN data transfer software; simple FTP clients are now in-
cluded in many web browsers.
Gateway Gateway is a general term designating an interface be-
tween two computer networks. Such a network interface
can be realized using a router or a bridge, for instance.
If a computer wants to transfer data packets to a computer
in another network, it must first transmit the packet to the
gateway. To do this, the computer must know the address
of the gateway.
If all packets that cannot be delivered in a local network
always are to be transmitted to their given recipients via
the same gateway, for this purpose the address of the
gateway must be saved as the default gateway in the net-
work settings of the computer.

Such a default gateway for the computer is negotiated au-
tomatically by the operating system or the dialing soft-
ware whenever an ISDN-Controller or DSL-Controller estab-
lishes a connection to the Internet. If a router is used for
the shared Internet access in a local network, the IP ad-
dress of the router must be entered as the default gateway
in the TCP/IP settings of each computer that wishes to use
the Internet connection. If the TCP/IP setting is configured
by means of a DHCP server, there is no need to enter the
gateway address manually.
IP abbreviation for Internet Protocol
The IP Internet Protocol is the most important basic proto-
col for the control of data exchange in local networks and
in the Internet. The Internet protocol works without a con-
nection; in other words, data packets are transmitted from
the sender to the recipient without previous consultation.
The addresses of the recipient and the sender in the data
packets are given as IP addresses.
IP Address abbreviation for Internet Protocol address
In IP-based networks, for instance in the Internet and local
networks, all connected devices are addressed via their IP
addresses. So that data packets are sure to be delivered
to the right address, each IP address may be assigned on-
ly once within the Internet or a local IP network.
The IP address consists of four three-digit groups of num-
bers (for instance, 192.168.178.247). Each group of num-
bers can assume values between 000 and 255.
Every IP address contains two components: the network
address and the host address. These two components can
be read out of an IP address only if the subnet mask is al-
so specified.
IP addresses can be public or private, and also fixed or as-
signed dynamically. See the corresponding entries in the
Glossary for more information.

IP Addressing Addressing is one of the main functions of the Internet
Protocol (IP). Internet addresses can be written in deci-
mal, octal or hexadecimal notation. The
FRITZ!WLAN Repeater uses “dotted-decimal” notation:
The four bytes of an address are represented by decimal
numbers separated by dots. The total volume of Internet
addresses, the address space, is separated into classes
(A, B, C, D, and E). The full set of IP addresses, called the
address space, is grouped into address classes designat-
ed as A, B, C, D and E. Only the first three of these five ad-
dress classes are actually used. These classes can be de-
scribed as follows:
Properties of IP Address Classes
Every IP address consists of two parts: the network ad-
dress and the host address. The sizes of the network ad-
dress and the host address are variable, and determined
by the first four bits (of the first byte) of the IP address.
IP
Masquerading
By means of IP masquerading a computer or LAN can be
protected from unauthorized connection request from the
Internet. Masquerading works by converting the IP ad-
dresses used in a network to one public IP address. From
the outside it appears that all requests are sent from a sin-
gle computer.
IP Network A network in which data exchange takes place on the ba-
sis of the Internet Protocol is called an IP network.

Public IP
Address
A public IP address is an IP address valid in the Internet.
Every computer or router participating in the Internet must
have a uniquely assigned public IP address. This address
is usually negotiated dynamically with the Internet Service
Provider when a connection to the Internet is dialed. The
Internet Service Provider assigns the negotiated IP ad-
dress to the computer or router for the duration of an Inter-
net session.
Private IP
Address
Private IP addresses are used for computers and other
network devices within local IP networks.
Since many local IP networks are not connected to the In-
ternet except via single computers or routers (gateway),
certain address ranges are excluded from the publicly
available IP addresses so that they are available for as-
signment in local IP networks. An IP address may only be
assigned once within the local network. A private IP ad-
dress may exist in any number of other local networks.
Subnetwork A local IP network can consist of one subnetwork or be di-
vided into multiple subnetworks. The division into subnet-
works is performed when the local IP network is config-
ured. The subnetworks of a local IP network are also IP
networks.
Subnet Mask The subnet mask indicates which part of an IP address is
the network address and which the address of the com-
puter. The network address defines what is called the sub-
net.
Example 1
IP address: 192.168.178.247
Subnet mask: 255.255.255.0
The assignment of the first three groups of numerals in the sub-
net mask indicates that the first three groups of numerals in the
IP address define the network. The following addresses result:
FRITZ!WLAN Repeater N/G 48
Glossary
Network address of the subnet: 192.168.178.0
Address of the computer in the
subnet:
192.168.178.247
IP address pool in the subnet: 192.168.178.0 -
192.168.178.255
The IP addresses
192.168.178.0 and
192.168.178.255 are re-
served. This means that the
addresses from
192.168.178.1 to
192.168.178.254 are avail-
able for assignment to the
computers. Therefore a maxi-
mum of 254 computers can be
included in the subnetwork
Example 2
IP address: 192.168.178.247
Subnet mask: 255.255.0.0
The assignment of the first two groups of numerals in the sub-
net mask indicates that the first two groups of numerals in the
IP address define the network. The following addresses result:
Network address of the subnet: 192.168.0.0
Address of the computer in the
subnet:
192.168.178.247
IP address pool in the subnet: 192.168.0.0 -
192.168.255.255
That’s 65,536 IP addresses.
The IP addresses 192.168.0.0
and 192.168.255.255 are re-
served. This means that the
addresses from 192.168.0.1 to
192.168.255.254 are avail-
able for assignment to the
computers.

TCP/IP abbreviation for Transmission Control Protocol / Internet
Protocol
TCP/IP is the “language” of the Internet. TCP/IP is used to
refer to a suite of protocols used for data communication
over the Internet. TCP and IP are the network and transport
protocols underlying most Internet services, including file
transfer (FTP) and e-mail communication (SMTP). TCP/IP is
available for practically all computer systems. TCP/IP thus
offers the advantage of trouble-free communication be-
tween otherwise incompatible networks and systems.
Update A more recent version of software or firmware is called an
update. Updates are often free of charge, resolve minor
programming errors, and sometimes also offer new func-
tions.
Upload This term designates the procedure of transmitting files
from one’s own computer to another computer in the Inter-
net.
UPnP abbreviation for Universal Plug and Play (UPnP)
UPnP is an extension of the Microsoft Plug & Play standard
that allows devices to network globally and to exchange
services—without a central server or computer.
UPnP allows devices from all kinds of manufacturers (ste-
reo systems, routers, printers, house controls) to be con-
trolled via an IP-based network, with or without central
control through a gateway. It is based on a number of
standardized network protocols and data formats. Ex-
pressed simplistically, devices can communicate with
each other using UPnP to exchange information.
Today the UPnP forum specifies the UPnP standard and
certifies devices that are compliant with the standard.
