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.
