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
en | 12
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.
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.
Note
You can change the power value of the wireless
access point (refer to section 11.6.4).
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.
Note
Wireless discussion units that have a software
version lower than 2.35 will only work when
language distribution is disabled.
For information on how to enable or disable language
distribution in the wireless network, refer to section
10.6.11.
Bosch Security Systems | 2007-11 | 9922 141 70691 en
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.
DCN Wireless | Installation and User Instructions | System Design and Planning
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.
Note
Although the system operates on frequencies
which are license free world wide, you must be
aware of country specific limitations and follow
them.
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.

Optical fiber length
3.6.5
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.
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.
3.6.4
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.
en | 18
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.

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).

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.

14.6.2 Procedure
•
If after pushing the microphone button for the first
time, the ring around the microphone button is
yellow for 250 milliseconds and then goes off, the
wireless discussion unit was already subscribed to
this system - you did not have to put the system in
subscription mode. Instead switch on the unit as
described in section 13.1 (if the software version of
the wireless discussion unit is lower than 2.35, the
ring around the microphone button is green for 2
seconds).
•
If after pushing the microphone button for the first
time, the yellow LEDs around the microphone
button, and the red indicator ring of the microphone
are on, the wireless discussion unit is already
subscribed to a system, but is not within range of this
system. If the unit cannot find the system within 15
minutes, it will automatically switch off (if the
software version of the wireless discussion unit is
lower than 2.35, the ring around the microphone
button alternates red and yellow for 5 seconds, and
then the unit automatically switches off).
•
If after pushing the microphone button for the first
time, the yellow LED comes on for 250 ms and the
red microphone indicator comes on and stays on, the
wireless discussion unit is already subscribed to the
system, but another unit with the same address is
already connected. To correct this, de-initialize the
unit as described in section 14.6.3, or push the
microphone button for a second time. The unit will
then de-initialize. If the unit is in range of the
wireless network and subscription is enabled, the
unit will also subscribe (if the software version of the
wireless discussion unit is lower than 2.35, the ring
around the microphone button alternates red and
yellow for 5 seconds, and then the unit automatically
switches off. De-initialize the unit as described in
section 14.6.3, and then subscribe the unit again).
The procedure below is applicable for wireless
discussion devices without a subscription. If the wireless
discussion unit already has a subscription, first erase the
subscription (refer to section 14.6.3).
Do as follows:
1 Set the wireless mode of the system to Subscription
(refer to section 12.3.5).
2 Insert charged batteries into the wireless discussion
units.
3 Push the microphone button of the wireless
discussion unit. All LEDs of the wireless discussion
unit come on and stay on, and the indicator ring of
the microphone comes on as red.
4 Push the microphone button of the wireless
discussion unit for a second time. The unit will try to
subscribe. If subscription is successful, all LEDs of
the wireless discussion unit, and the indicator ring of
the microphone go off (if the software version of the
wireless discussion unit is lower than 2.35, all LEDs
go off after 2 seconds, and the LED around the
microphone is green for 5 seconds indicating that the
subscription was successful. A second push on the
microphone button, as required for units with
software version 2.35 or higher, is not required).
•
If after pushing the microphone button for a second
time, all LEDs around the microphone button and
the indicator ring of the microphone come on again,
the wireless discussion unit is either not within range
of the wireless network, or the wireless mode is not
set to Subscription (if the software version of the
wireless discussion unit is lower than 2.35, and after
pushing the microphone button for the first time, the
ring around the microphone button alternates red
and green for 5 seconds, the unit is either: not within
range of the wireless network, the wireless mode is
not set to Subscription, or the language distribution is
enabled). Refer to the note under Limit 4 in section
1.
