1 Wireless network design
1.1 Introduction
The DCN Wireless has three parts: the wireless
network, the DCN and the optical network. This
chapter tells how to design the wireless network.
1.2 Limits
Limit 1: Control capacity
The maximum number of devices in the wireless
network that the central control unit can control is 150.
Limit 2: Coverage area
For a good operation of the wireless part, all wireless
discussion units need to be in range of the wireless
access point. The wireless access point has a typical
maximum coverage area of 30 m by 30 m. To
determine the exact coverage area the coverage test kit
can be used.
Limit 3: Frequency
The wireless network must operate in a different
frequency band than adjacent wireless (computer)
networks (refer to section 1.3).
Limit 4: Language Distribution enabled or
disabled
If all wireless discussion units have software version 2.35
or higher, language distribution in the wireless network
can either be enabled or disabled. This system setting
will affect all units.
For information on how to enable or disable language
distribution in the wireless network, refer to section
10.6.11.
Wireless discussion units that have software version 2.35
or higher have improved signaling and behavior with
respect to subscription and connection, which is more in
line with the wired DCN units (refer to section 14.6).
The difference in signaling can be used to detect the
software version of the unit. This can be 2.35, or a
higher or lower version.
If the wireless discussion unit has an integrated channel
selector, the software version is shown on the channel
selector display when:
• the unit is switched on but is not subscribed to a
wireless network (refer to section 14.6 for
information on subscription).
• the unit is in programming mode (refer to section
14.3.1).
For information on how to enable or disable language
distribution in the wireless network, refer to section
10.6.11.
Limit 5: Number of Language Distribution
Channels
The wireless network has a maximum of 10 language
distribution channels, excluding the channel for the
floor. The total number of language distribution
channels in the system, is set via the interpreter desk
(refer to section 33.6.6.4 in the DCN Next Generation
Installation & User Instructions).
If there are more than 10 Language Distribution
Channels, only the first 10 channels will be available for
the wireless network. All higher channels will only be
available for the (wired) DCN network and/or the
infrared Integrus network.
Note
You can change the power value of the wireless
access point (refer to section 11.6.4).
Note
Wireless discussion units that have a software
version lower than 2.35 will only work when
language distribution is disabled.

1.3 Frequency band
1.3.1 802.11g specification
The wireless network is based on the 802.11g
specification for WiFi technology. Devices that comply
to the 802.11g specification operate in frequency bands
between 2.4000 and 2.4835 GHz.
1.3.2 Wireless computer networks
Wireless (computer) networks can also be based on the
802.11g specification for WiFi technology. In the
wireless computer networks, 13 overlapping channels
are available (refer to figure 1.1).
1.3.3 Carriers
In the wireless network of DCN Wireless, three
non-overlapping wireless carriers are available (refer to
figure 1.2).
1.3.4 Interference
The wireless network of DCN Wireless can cause
interference on wireless computer networks. You must
make sure the DCN wireless carrier does not overlap
the WLAN channel.
Refer to figure 1.3. In the example, the WLAN channel
is 3. WLAN channel 3 overlaps DCN wireless carriers 0
and 1. Therefore, use DCN wireless carrier 2.
Note
Although the system operates on frequencies
which are license free world wide, you must be
aware of country specific limitations and follow
them.

3.5.3 Power supply
The CCU supplies power for:
• the optical network, and
• the units connected via the DCN cables.
Refer to figure 3.1.
If more power is necessary, you must install external
power supplies in the optical network. The devices
below can connect to external power supplies:
• LBB4410/00 Network Splitter (refer to the DCN
Next Generation Installation and User Instructions).
• LBB4414/10 Fiber Interface (refer to the DCN Next
Generation Installation and User Instruction).
3.5.4 Overload indication
Each optical network socket of the central control unit
has a red LED that comes on to show that there is a
power overload. An overload occurs when the
necessary power for the devices is greater than that
supplied. The sockets are deactivated and the devices
connected to the central control unit do not operate.
The socket checks every 8 seconds for power overloads.
3.6 Cabling
3.6.1 Introduction
Many devices in the optical network have two optical
network sockets that are interchangeable. You can use
the two optical network sockets to make a redundant
ring.
3.6.2 Definitions
The optical network uses two types of cable:
•POF
Plastic Optical Fiber.
•GOF
Glass Optical Fiber.

3.6.3 Optical fiber length
Because of optical attenuation, the maximum length of
optical network cables (LBB4416) is 50 m. You can use
GOF and fiber interfaces to increase the distance
between devices to a maximum of 1500 m.
3.6.4 Cable couplers
You can use the LBB4419/00 Cable Couplers to
connect optical network cables to each other. A cable
coupler causes optical attenuation. Each cable coupler
decreases the maximum distance between two devices
in the optical network (normally 50 meters) with
20 meters.
3.6.5 Maximum cable length
The maximum cable length (LBB4416 and GOF) of the
optical network is dependent on:
• The number of nodes
• The number of LBB4414/10 Fiber Interfaces
Do as follows:
1 Find the number of nodes of each device from the
node value table (refer to table 3.1). Add together the
nodes of all devices.
2 With the value of step 1, use the graph (refer to
figure 3.2) to find the maximum cable length without
LBB4414/10 Fiber Interfaces.
3 Count the number of LBB4414/10 Fiber Interfaces.
Each fiber interface decreases the maximum cable
length from step 2 with 18 m.
Note
If the distance between two devices is less than
100 m, use a network splitter between devices
to remove the use of fiber interfaces. Use only
the trunk sockets of the network splitter in this
case.

3.6.6 Bending
The minimum bend radius of a 90 degree bend in an
LBB4416 cable is 110 mm (refer to figure 3.3). A
180 degree bend is the same as two 90 degree bends.
3.6.7 Coiling
The minimum coiling radius of an LBB4416 cable is
110 mm (refer to figure 3.4).
3.7 Example layouts
3.7.1 Introduction
The number and type of devices that make the optical
network give the layout of the optical network. This
chapter shows examples of the possible layouts of
optical networks.

3.7.2 Basic optical network
Refer to figure 3.5 for an example of a basic optical
network.
3.7.3 Extended optical network
Refer to figure 3.6 for an example of an extended
optical network.
3.7.4 Redundant cables
The example of the extended optical network (refer to
figure 3.6) has no redundant cable. If the cable between
the central control unit (DCN-WCCU) and the wireless
access point (DCN-WAP) breaks, the central control
unit cannot transmit data to the wireless access point. A
solution for this problem is to use redundant cable (refer
to figure 3.7 for an example).
The example of the system without redundant cable
(refer to figure 3.6) has no connection between the
cobranet interface (LBB4404/00) and the central control
unit (DCN-WCCU). The example of the system with
redundant cable has a connection between the Cobranet
Interface and the central control unit. This connection
makes a ring. If a cable breaks, the optical network
continues to operate.
The total power of all devices in the redundant optical
network is 65 W. If the optical network is defective near
the central control unit, the other socket can supply
power to all of the optical network.
